In a modern Sacramento home, high-tech heat pumps, ACs, high-efficiency furnaces, whole-home humidifiers, air purifiers, and other electronics are linked to your electrical panel. Because they contain sensitive electronics and microprocessors, there is a potential risk whenever power surges occur.

Worse still, power surges don’t just happen because of lightning. Each time a high-powered appliance is plugged in, it draws enough energy to cause a surge. Damaged wiring, overloaded circuits, and grid issues are also common causes of unexpected surges.

Because of this, we typically recommend homeowners install a surge protection system. A point-of-use surge protector can stop power surges from damaging the sensitive electronics in your heating, ventilation, and air conditioning (HVAC) system.

What Is an HVAC Surge Protector and What Does It Actually Do?

A surge protector is designed to divert or limit this excess voltage before it has a chance to harm your sensitive components. Surge protectors are primarily effective for protecting electronics. While motors can be damaged by power fluctuations, surge protectors aren’t able to protect them.

It’s also important to note what surge protectors can and can’t do. They operate differently from breakers. Rather than providing guaranteed protection against events, they offer a good level of coverage. Because of this, they are most effective when used as part of a layered approach.

What Causes Power Surges and Voltage Spikes?

Power surges and voltage spikes can occur because of a few common events.

• Lightning nearby, even when there isn’t a direct strike
• Downed lines from trees and accidents
• Power outages and restoration following the outage
• Generators or solar inverters are switching on
• Large appliances cycling on, such as HVAC systems, fridges, and sump pumps
• Utility switching and transformer issues
• Brownouts, which are periods of low voltage that cause added stress on electronics and motors

While you might think of dramatic lightning strikes when you hear someone talk about power surges, the reality is that surges are far more frequent and unassuming.

What Parts of Your HVAC System Are Most Vulnerable?

Today’s HVAC systems have microprocessors and delicate components that can become damaged by unexpected surges.

• Control Boards and Ignition Boards: These serve as the brain of the HVAC system and can become fried by a surge.
• Thermostat and Smart Controls: Microprocessors in modern thermostats can fail or have incorrect readings due to surge damage.
• Inverter and Variable-Speed Drive Boards: These components are incredibly sensitive and costly to replace.
• Outdoor Unit Electronics and Contactors: Because they are outdoors, these components are more exposed to lightning. When exposed to high voltage, coils in the contactor can burn out.
• Capacitors and Relays: Capacitors can develop a dielectric breakdown due to surges, causing a telltale bulge in the metal. Meanwhile, relays can fuse shut or stop working.
• Compressors: While compressors experience less direct risk, the damage can be more expensive. Surges can lead the compressor to overheat and fail.

Replacing electronics can quickly get expensive. This type of failure tends to occur fast and unexpectedly, leaving your loved ones without a heating and cooling system.

Breakers vs. Surge Protectors: Why a Breaker Isn’t Enough

A breaker panel is designed to protect against overcurrent and shorts, but not voltage spikes. When the overcurrent or short is detected, it trips the breaker, and power is shut off to that circuit.

Unfortunately, surges can occur too fast for a breaker to trip. Because of this, surge protectors are essential for protecting homes from damage.

• Myth: My breaker will protect my AC. In reality, the breaker can’t respond quickly enough to a power surge.
• Myth: Surges only happen during storms. Power surges can happen from appliances switching on, grid fluctuations, transformer problems, downed lines, and other issues.

Whole-Home Surge Protection vs. HVAC Surge Protector: Which Do You Need?

There are a few things you should consider if you are trying to decide between whole-home surge protection and an HVAC surge protector.

Whole-Home (Panel) Surge Protection

A whole-home surge protector is intended to protect the circuits on your circuit panel at their source. While it offers a good level of baseline protection, it doesn’t always eliminate spikes inside your home that occur at the equipment level.

Dedicated HVAC Surge Protector

A dedicated HVAC surge protector is installed near your outdoor unit, although it may sometimes be installed near indoor equipment. It is designed to provide a focused layer of protection where the risk is at its highest.

Best Practice Approach: Layered Protection

A whole-home and HVAC surge protector complements each other as part of a layered protection system. If an internal surge occurs or an external surge breaks through the whole-home surge protector, the HVAC unit protection is in place to protect your system. This type of approach is especially important for new systems, expensive boards, and variable-speed heat pumps.

Is an HVAC Surge Protector Worth It? Use This Quick Checklist

To decide if investing in an HVAC surge protector is worth it, consider the following questions. An HVAC surge protector is generally a good idea if:

• You have a relatively new HVAC system.
• Your area frequently experiences storms, outages, or flickering power.
• You have a generator or solar inverter that switches on.
• You use a heat pump or variable-speed system.
• Your home has suffered from blown capacitors, boards, and thermostats before.
• Your outdoor unit was expensive, so you want to extend its lifespan.

However, you might not need an HVAC surge protector if:

• Your system is old or near the end of its expected lifespan.

Often, most homeowners will end up installing a surge protector because it is much cheaper than the cost of a single board repair.

What To Look for in an HVAC Surge Protector

Once you decide to install a surge protector, remember to consider the following factors.

• Type: You need to get an HVAC-rated, outdoor-rated surge protector.
• Indicator Status: There should be an indicator light that shows when the unit is working.
• Protection Rating: A higher kiloampere (kA) rating is better because this shows the protector can handle a higher level of electrical current.
• Warranty: Don’t look for satisfaction guarantees. Look for product warranties, and make sure to read through the fine print.
• Location: Consider the location where you’ll install the protector. It will need to have a good grounding in a place that is close to your equipment.
• Professional Installation: To ensure your code compliance and the safety of your home, you should get the unit professionally installed.

It pays to be proactive about finding the right surge protractor. If you get a cheap, non-rated device, there’s an excellent chance it won’t be able to hold up outdoors.

Installation: Where It Goes and What Installation Usually Includes

During the installation process, a technician from Fox Family Heating and Air Conditioning will take care of the following steps.

• Confirm your HVAC system type and electrical setup.
• Check disconnect and panel conditions to ensure your electrical system is safe and ready for the installation.
• Install and test the protector.
• Verify grounding.
• Clearly label the surge protector.
• Walk through the final setup with the homeowner. Demonstrate how the indicator light shows when the unit is working.

Common Questions and Misconceptions

Do I need a surge protector if I already have a whole-home surge protector?

Point-of-use surge protectors are still useful if you have a whole-home surge protector. In addition to offering a layered approach to defense, these surge protectors also protect your HVAC equipment from surges that occur within the home. This is especially important because whole-home systems primarily focus on protecting against surges from external sources.

Will a surge protector protect my compressor?

By diverting excess voltage to a grounding wire, a surge protector can protect your compressor from sudden energy spikes and power surges. Although compressors deal with indirect risks, surges can still cause overheating that can harm the compressor’s components.

Can a surge protector stop damage from a direct lightning strike?

No. Lightning contains millions of volts of energy, which is too much for a surge protector. To provide the best level of protection, you’ll likely need to install a lightning rod.

Do surge protectors wear out? How do I know if it still works?

Most surge protectors last for around two to five years. They have a “ground” or “protected” light that should be on all the time. If this status light flickers or shuts off, you need to get a replacement. Similarly, frequent tripping and signs of physical damage indicate that a replacement may be necessary.

Is a power strip surge protector the same thing?

No, they aren’t. A power strip is basically an extension cord with extra outlets. In comparison, a surge protector has the capacity to protect your electronics from electrical surges.

Do mini-splits or heat pumps need surge protection, too?

Absolutely. Surge protection is essential for any sensitive electronics that you don’t want damaged by lightning strikes. By investing in surge protection, you can reduce the likelihood of future repairs and replacements.

Improve the Safety of Your Home’s Electrical Systems

Surges can damage modern HVAC electronics, resulting in high repair costs and potential safety hazards. By investing in layered protection, homeowners can prevent damage and save money on HVAC repairs. If you are thinking about getting a new system or have unstable power in your home, installing a surge protector is a wise decision.

You’ve just curled up with a good book and a blanket. In the distance, you can hear the furnace kick on. Before you can even finish the page, it suddenly shuts off and leaves your home feeling chilly.

Unfortunately, this type of problem is common in Sacramento. If your furnace is short cycling, it can immediately cause comfort issues and more expensive energy costs. Over time, it will also increase wear on components. Short cycling can also be due to a safety shut-off, so this isn’t an issue that can be ignored.

By understanding the warning signs and when to call a professional at Fox Family Heating & Air, you can keep short cycling from impacting your comfort and energy bills this winter.

What Is Furnace Short Cycling? (And Is It Ever Normal?)

Short cycling is when a heating cycle starts, ends, and restarts too soon. When your system is operating properly, you’ll normally notice two to three runtimes per hour and a consistent indoor temperature.

In many cases, short cycling is a safety response triggered by your system to prevent damage. Because of this, it’s important to address the underlying problem.

Key Signs Your Furnace Is Short-Cycling

You may be experiencing short cycling if:

• Your furnace shuts off within a few minutes of starting.
• It immediately starts again right after it stopped.
• Your home experiences uneven temperatures.
• It doesn’t feel like your home is heating up all the way.
• Your furnace seems to run intensively, but it doesn’t actually result in a warmer home.
• You notice frequent thermostat “calling” without an improvement in comfort.
• Your energy bills have gone up without any significant change in the weather.
• You hear loud start and stop sounds, clicking, or whooshing.

Important Safety Note: If you notice a burning odor, gas smell, soot, or repeated breaker trips, immediately stop using your furnace and call for help.

Most Common Causes of Furnace Short Cycling

To get a better understanding of how furnace short cycling works, let’s look at common causes, what you can check, and how a professional can help.

Dirty Air Filter or Restricted Airflow

Any airflow problems, like clogged filters, closed vents, and blocked returns, can cause the furnace to overheat. In turn, this can cause your limit switch to trip and shut down the furnace.

You can troubleshoot by replacing the air filter. Then, open your vents and make sure your return grilles are clear.

Thermostat Problems

If the thermostat’s location, calibration, wiring, or settings are wrong, it can lead to short cycling. For instance, placing a thermostat in the sun can cause it to shut off early.

Troubleshoot this malfunction by checking the batteries and temperature settings. Also, make sure the thermostat isn’t placed in the sun or a draft.

If these DIY tips don’t work, call a heating, ventilation, and air conditioning (HVAC) technician for help. We’ll evaluate the unit’s wiring, calibration, and setup to ensure it’s working correctly.

Flame Sensor Issues

For gas furnaces, a faulty flame sensor will shut off the furnace right away because it can’t detect the flame. The best way to fix this is by calling an HVAC technician for a professional burner inspection, cleaning, or replacement.

Overheating Due to Blower or Ductwork Issues

Blower motor issues, duct restrictions, and dirty blower motor wheels can cause high static pressure, which triggers a safety shutoff. With the help of a professional, you can test the blower, airflow, and ductwork for signs of a problem.

Blocked Venting or Intake

When an intake or vent is blocked on a high-efficiency furnace, it can cause a pressure switch fault and safety shutoff. On your own, you can look for signs that the visible exterior vent termination has a blockage. For a full venting inspection and combustion analysis, call a professional.

Limit Switch or Rollout Switch Tripping

If a limit switch or rollout switch triggers the furnace to shut down to prevent flame rollouts and overheating, this is an immediate safety issue. Immediately call a professional to investigate and fix the root cause.

Oversized Furnace

An oversized furnace will heat too fast and shut off right away. As soon as the temperature dips again, it will switch back on and do the same cycle. Besides impacting your energy bill, this can cause major swings between temperatures and less even heating performance.

Dirty Burners or Gas Pressure Issues

Poor combustion can result in shutdowns and make your furnace operate erratically. This issue must be fixed by a professional HVAC technician. Once one of our team members arrives at your home, they can ensure proper combustion by cleaning the burners and checking your manifold pressure.

Condensate Drain Problems

A condensing furnace relies on a condensate drain line. If it becomes clogged, the float switch will trip. You can check for the drain line blockage on your own if it is visible. Otherwise, you can call a professional to get the line cleared and trap checked. We will also verify proper pitch before we leave to prevent this from happening again.

What To Check First: A Safe, DIY Checklist

If you need immediate help with your furnace’s short cycling, try the following checklist.

• Set the thermostat to “Heat” mode and raise the temperature by 2℉ to 3℉ to see how the unit responds.
• Replace the air filter with a correctly sized filter.
• Ensure your supply vents and return are open and unobstructed.
• Check your furnace power switch.
• Make sure your panel door is closed all the way.
• Listen to see if the furnace ignites and shuts off right away, which indicates a flame sensor problem.
• Repeated shutdowns are signs of an issue. When this happens, turn off your furnace and schedule professional diagnostics.

Don’t DIY These Tasks

• Electrical component testing
• Gas pressure checks
• Burner adjustments
• Bypassing safety switches

When Short Cycling Becomes an Emergency

You should immediately stop using your furnace and call for help if you notice any of the following symptoms.

• The smell of rotten eggs or burning odors
• Soot around your furnace cabinet or vents
• Repeatedly tripped breakers
• A carbon monoxide alarm going off
• Visible flame rollout
• Booming when the furnace ignites

FAQs

Why does my furnace turn on and off every few minutes?

This is known as short cycling. It often stems from a dirty, worn, or faulty component. To avoid high energy costs and more frequent repairs, it’s essential to get this symptom looked at.

Can a dirty filter really cause short cycling?

Absolutely. When airflow is low, it can result in the furnace overheating. In turn, this causes the furnace to switch off as a safety mechanism.

Why does my furnace start, ignite, then shut off right away?

This is known as short cycling. It can be caused by multiple problems, but dirty heat sensors and clogged air filters are the most common issues.

Is furnace short cycling dangerous?

Yes, it is. Repeated short cycling can crack the heat exchanger, leading to carbon monoxide leaks in your home. It is also a potential fire hazard.

Will short cycling increase my energy bill?

The frequent on-and-off cycles lead to higher energy consumption because the start-up phase is the most energy-intensive part of the cycle. This type of cycling also prevents your furnace from reaching its optimal temperature, leading to higher energy consumption. Over time, short cycling will lead to significantly higher energy bills.

Can an oversized furnace be adjusted, or does it need replacement?

There are steps we can take to adjust the furnace, such as reducing the burner rate or blower speed. However, in many cases, the most effective option is to get an accurately sized furnace replacement.

What does a faulty flame sensor look like in real life?

If you’re looking at it, you’ll likely notice soot buildup, corrosion, or cracked porcelain. A faulty sensor may struggle to detect the flame, so it will likely cause short cycling when your unit is on.

How do I know if it’s the thermostat or the furnace?

When you adjust the temperature, listen for a click. This indicates the thermostat is correctly triggering the furnace to turn on. You can also troubleshoot thermostat issues by verifying that it is set correctly and changing batteries. For more extensive checks, reach out for professional help.

Keep Your Furnace From Short Cycling

While short cycling is typically fixable, it is important to catch it early. Otherwise, a minor problem can escalate into a costly, inconvenient breakdown. By performing routine maintenance, you can prevent this issue from recurring.

As that first wintertime heating bill arrives, it’s normal to start looking for ways to save on costs. An unused guest room, empty office, or chilly hallway seems like a waste of money to heat. While it might be tempting to close up vents and stop heating unused spaces, this can actually cause problems for your heating, ventilation, and air conditioning (HVAC) system.

To start saving money, let’s look at how closed vents impact your HVAC system and at better ways to save money.

Quick Answer

You probably won’t break anything by closing just one vent. However, you can experience problems if you close many vents because the airflow has to go somewhere. Restricting it can change the air pressure inside your duct system.

Static Pressure Explained

Think of static pressure like the air traffic in your ducts. When you open your vents, the air can take different exits. Closing the vents shrinks the number of exits, causing increased pressure in your ducts. Basically, it’s like pinching the end of a garden hose to make a high-pressure spray of water.

What Really Happens When You Close Vents in Unused Rooms

Let’s take a closer look at what happens when you shut vents in your unused rooms.

Pressure Goes Up, Airflow Goes Down

While the blower is working just as hard, the system is restricting where that air can go. As a result, your home’s airflow drops.

The Air Doesn’t Magically Reroute Perfectly to the Rooms You Want

You can’t choose where the extra air ends up going. Instead, some rooms may end up with more and others with less. It all depends on your duct layout.

Leaks Get Worse

Because of the added pressure, more air can get pushed out of existing duct leaks in your crawlspace or attic.

Comfort Can Actually Get Worse

Your comfort level can become worse because of more drafts and uneven heating. You may also experience noisy vents and whistling sounds.

The Equipment Side: Why HVAC Systems Don’t Love High Static Pressure

HVAC systems struggle to deal with increased pressure. As a homeowner, you’ll likely notice the following symptoms and side effects.

• Blower Stress: The blower has to work harder to transfer air, leading to more frequent repairs.
• Heating Performance: The changed airflow can result in less heat reaching your rooms.
• Noises: Whistling, whooshing, and rattling sounds can occur because of the changed airflow.
• Reduced Energy Efficiency: You will potentially spend more on energy due to longer run times.
• Overheating: When airflow is restricted, your furnace can overheat and trigger safety limits. You may notice it short cycling more frequently.

Is It Ever Okay To Close Your Vents?

There are some general situations where you may be able to close your vents, but it’s important to exercise caution.

Usually Okay:

• Closing just one or two vents for a little bit in a small section of your home
• Closing a vent in a specific room that gets excess airflow so that it is better balanced
• Partially closing the vent instead of closing it all the way

Use Caution or Avoid:

• Closing too many vents in your home
• Closing vents in a room that has a thermostat or a key return pathway
• Closing vents in homes with older ductwork or airflow problems
• Closing vents in areas that have undersized returns

Why Your “Unused Room” Still Matters in Winter

Even though you might not be using the room all winter, it still matters to your home’s comfort and the health of your HVAC system. When vents and doors are cold, it can make the room extremely cold. The cold walls, floors, and drafts can cause neighboring rooms to experience comfort issues. If the unused room gets cold enough and has any exterior walls with plumbing, the frigid air can even result in frozen or burst pipes.

Better Ways To Save Money Without Choking Airflow

Rather than stifle your home’s airflow, try using the following tips to save money.

Use Smaller Thermostat Setbacks Instead of Closing Vents

A small setback can save money on energy costs when you’re away or asleep.

Keep Doors Open or Crack Them for Airflow Balance

Opening doors helps with airflow balance, especially if the room has problems with its return pathway.

Make Sure Your Filter Is Clean and the Right Type

The filter should be clean and the correct type. If it gets dirty, it can cause airflow restrictions that are just as bad as closed vents.

Address Drafts and Insulation First

Weatherstripping, filling gaps in your attic insulation, adding door sweeps, and repairing leaky ductwork can save you more money on energy costs than closing vents.

Consider Professional Airflow Balancing

By reaching out to our HVAC technicians for airflow balancing, you can get your dampers, returns, and supply distribution adjusted properly.

Zoning (Only if It Makes Sense)

If balancing isn’t enough to fix your comfort problems or you have a large home, you may want to use zoning. However, this step should only be taken if easier and more affordable alternatives don’t improve your family’s comfort.

Quick Homeowner Check: Signs You’ve Closed Too Many Vents

You may have closed too many vents if:

• You hear whistling or hissing noises in your vents.
• The airflow feels unusually weak.
• Your HVAC system turns on and off frequently.
• The furnace is louder than normal.
• Your home’s heat is uneven in different rooms.
• Some of your rooms are stuffy.

What To Do if You Have Already Closed Vents

To remedy your closed vents, start by reopening the majority of them. Returns should be open and unobstructed. Then, check to see if your filter needs to be cleaned or replaced.

If these steps don’t work, schedule an airflow check. Your system may need balancing or duct leak repairs.

The Goal Isn’t Fewer Vents, It’s Better Comfort per Dollar

When you close vents, it increases the static pressure in your home. This can negatively impact your comfort and the efficiency of your HVAC system. By adopting smarter measures to save energy, you can reduce your bills without overly stressing your HVAC system.

Reach out to Fox Family Heating and Air Conditioning for help with uneven heat and higher energy bills. We can quickly test your airflow to diagnose and fix the real culprit.

FAQs

Can closing vents damage my furnace?

Yes, it can. It creates added pressure, which can strain your blower motor and other components. If you have multiple closed vents or close them for extended periods of time, you’ll experience worse wear and tear.

How many vents are too many to close?

If more than 20% of your home’s vents are closed, it can lead to increased wear. Additionally, you shouldn’t close vents in any space that has a major return pathway. If you find yourself closing multiple vents, it’s always better to schedule an airflow inspection.

Should I close vents upstairs or downstairs in winter?

Your system is working at its hardest during the wintertime, so you avoid closing any vents. This can result in increased wear and more frequent repairs. If you want to reduce airflow in one area, it’s better to partially close a single vent instead of shutting every vent on an entire story of your home.

Is it okay to close vents in a room with the door shut?

No, it is generally not a good idea. Closed vents and shut doors limit airflow and increase pressure in your HVAC system.

What’s the difference between closing vents and having a zoned system?

A zoned system uses dampers to manage air distribution. While closed vents increase pressure and can cause damage, getting a zoned system can improve your home’s comfort, reduce energy costs, and ensure consistent airflow to the areas you are using the most.

It’s a typical winter day in Sacramento. You’re just getting ready for work when you notice that your thermostat says “aux heat.”

While it’s normal to see “aux heat” on your thermostat, it may also be a sign your system is working harder than necessary. To figure out if this setting indicates a problem, let’s look at what it means and when you should call for help.

“Aux Heat” in Plain English: Backup Heat for a Heat Pump

A heat pump transfers heat from one location to another. In comparison, furnaces actually create heat.

While modern heat pumps are incredibly efficient and can work in extremely cold temperatures, there may be times when the heat pump can’t keep up. Depending on the design of your heating, ventilation, and air conditioning (HVAC) system, you may have heat strips or a gas furnace installed for backup heat.

“Aux Heat” vs. “Emergency Heat”

Auxiliary heat is functionally different from emergency heat.

• Aux Heat: This heat automatically kicks on to help your heat pump reach and maintain a certain temperature. You’ll normally see it kick on during extremely cold temperatures or during times of heavy demand.
• Emergency Heat: Meanwhile, emergency heat must be manually selected by the user. It’s typically used if you have to shut down your heat pump or if the heat pump isn’t working. Because it costs more to run than the heat pump, its sole purpose is to help you get by until the heat pump is operational again.

Why Your Thermostat Shows “Aux Heat”

There are a few common reasons why your thermostat may show that it is using auxiliary heat.

It’s Cold Outside, and the Heat Pump Needs Help

When it’s extremely cold, auxiliary heat may need to switch on to support your heat pump’s effectiveness and your home’s comfort.

The Thermostat Is Trying To Recover After a Big Temperature Change

If you use big setbacks or need to warm up your home significantly in the morning, your heat pump may require “aux heat” mode to catch up.

Your Heat Pump Is in Defrost Mode

During defrost, the heat pump switches direction in order to warm up the outdoor coils and melt any ice. As a result, your heat pump must use a backup heat source to maintain your home’s temperature.

Your System Is Undersized, or Your Home Loses Heat Fast

If you have an undersized system, significant drafts, or insulation issues, your heating system may rely on auxiliary heat more frequently.

When “Aux Heat” Is Totally Normal (And Nothing To Panic About)

On the coldest mornings of the season, it’s normal to rely on auxiliary heat. Additionally, this mode is used for short periods of time when outdoor temperatures suddenly drop and during the defrost mode.

When “Aux Heat” Is a Red Flag (And Can Spike Your Bills)

You need to schedule professional heat pump repairs if you notice “aux heat” kicks on in the following situations.

• “Aux heat” is on constantly, even in warmer temperatures.
• Your home still won’t warm up.
• “Aux heat” kicks on after minor thermostat changes.
• It seems like your thermostat is stuck in “aux heat.”
• Your vents are producing lukewarm air.
• The electricity bill has spiked without any explainable reason.
• Your HVAC system seems like it is running nonstop.

The Comfort-Cost Connection: Why “Aux Heat” Can Get Expensive

While it’s important to stay warm, backup heat uses more energy than your heat pump’s normal operations. If your backup heat is on more, you’ll end up spending more on your energy costs. It’s essential to perform necessary repairs and schedule routine heat pump maintenance so that your system doesn’t have to rely on backup heat sources.

How To Reduce Unnecessary “Aux Heat” Without Freezing

When outdoor temperatures are freezing, you can’t afford to go without heat. Fortunately, there are a few things you can do to stay warm without relying on auxiliary heat all the time.

Thermostat Habits

Try to make small adjustments and gentle schedules instead of aggressive setbacks and major jumps. Don’t crank the heat all the way up to warm up your home.

Airflow Basics

Ensure your system is operating efficiently by regularly changing the filter. Additionally, clear your vents and returns.

Home Comfort Basics

Avoid heat loss by sealing drafts around your doors and windows. To improve circulation, keep your interior doors open.

Quick Troubleshooting: What To Check Safely at Home

As a homeowner, there are a few questions you can ask to troubleshoot why auxiliary heat is on.

• Did you recently adjust the thermostat’s schedule or add a major setback?
• Is your thermostat turned to “heat” and not “emergency heat”?
• Does the air filter look clogged or dirty?
• Is there uneven heating in specific areas, indicating a duct problem?
• Are there any rugs or furniture blocking your returns?

When To Call a Pro (And What We’ll Typically Look At)

You should call for heat pump service in the following situations.

• The HVAC system is unable to maintain your set temperature.
• You think there is an airflow or duct-related issue.
• Your home’s comfort level has declined, and you’re also experiencing high energy bills.
• You notice that “aux heat” appears frequently on mild days.

Aux Heat Isn’t “Bad”- It’s a Signal

When “aux heat” appears on your thermostat, it’s a sign your system is working the way it should. However, auxiliary heat should only be a backup. If it is running all the time or your home doesn’t stay warm, it’s time to get a professional inspection. Fox Family Heating and Air Conditioning can check your airflow and HVAC performance to determine the underlying problem.

Book your next HVAC appointment to identify problems and enjoy consistent comfort this winter.

FAQs

Does “aux heat” mean my heat pump is broken?

No, it doesn’t. “Aux heat” comes on when your heat pump is using its backup heat source. It may be due to an especially cold day or because the heat pump is defrosting the outdoor coils. However, you should get help if you notice auxiliary heat coming on all the time or your home struggles to stay warm.

Why does “aux heat” turn on when I raise the temperature?

Sometimes, your heat pump needs an extra boost to get to the right temperature. This is a more common issue when major thermostat changes are involved. By using smaller changes and moderate setbacks, you can avoid relying on auxiliary heat.

Is it normal to see “aux heat” during defrost?

Yes, it is. The heat pump is warming the outdoor coils, so it isn’t heating your home. During this brief interlude, your auxiliary heat keeps your home warm.

How can I keep “aux heat” from running so much?

Moderate setbacks, smaller temperature differences, and consistent HVAC maintenance can help your heat pump perform its best during wintertime conditions.

Will a dirty filter cause “aux heat” to run more?

Yes, it can. If the filter is clogged, your airflow will suffer. This makes your heat pump less efficient, forcing it to rely on auxiliary heat more often.

Compared to snow country, Sacramento has relatively mild winters. Despite this, heating bills can still add up quickly. From setbacks that make you shiver to costly high thermostat temperatures, there are a few common thermostat settings that may be costing you money or comfort.

To help you stay comfortable this winter, we’ll dive into the best setback strategy for balancing comfort and energy consumption.

What a “Setback” Really Means (And Why It Works)

A setback is when you set the temperature back when you’re away or asleep. It saves you money by allowing you to avoid heating the house when you don’t need the added warmth. Even minor changes can have a real impact on your energy bills.

Before You Set a Schedule: 3 Quick Questions

To figure out the setback that works best for your budget and comfort needs, consider the following questions.

• When do you typically wake up and leave your home on weekdays?
• Does anyone stay home during the day, such as pets, remote workers, or children?
• Do you like sleeping in a cool or warm room?

The Comfort-First Rules (So You Don’t Feel Cold)

For the best results, remember the following comfort-focused tips.

• Stick to moderate setbacks. Changes don’t have to be dramatic to save you money.
• Set the thermostat to gradually warm up your home before you get up and before you return from work.
• If your thermostat is having a hard time recovering, set it to a warmer temperature during your away or asleep hours so that it doesn’t have to catch up so much.

Recommended Winter Thermostat Schedule for Sacramento (Weekdays)

To help you stay comfortable during the week, try adjusting your home’s temperatures to match the following schedule.

Weekday Schedule Template: Typical 9–5 Household

• Overnight (Sleep): You should set it so that it is a lower temperature but still comfortable.
• Morning (Getting Ready): For your comfort, set the thermostat a little higher as you wake up.
• Daytime (Away): When your home is empty, set the temperature back a bit.
• Evening (Home): Raise the temperature once everyone arrives home.
• Late Evening (Wind Down): As you get ready for bed, set the temperature back a little bit.

Why This Works

This type of schedule allows you to enjoy a warm home when you’re awake. When you’re asleep and snuggled up in blankets, you save money by having a lower temperature. The schedule lets you avoid waking up cold and ensures predictable run times.

Recommended Winter Thermostat Schedule for Sacramento (Weekends)

On weekends, people are often home more. The added hours of relaxation mean you’re moving less and need the thermostat to be set a little higher.

Weekend Schedule Template: Home More and Sleeping In

• Overnight: Set your overnight temperature to the same as weekdays.
• Morning: While the morning temperature should be the same as your weekday schedule, you should adjust the time because you wake up later.
• Midday: Keep a steady comfort range and don’t have any big swings.
• Evening: Opt for your preferred comfort setting.
• Night: Drop the temperature level at night.

Why Weekends Should Be Different

You don’t want to keep the same schedule on the weekends because the daytime setting will likely feel too cold. A smaller midday setback allows you to save money without hurting your comfort.

Schedules for Real Life

Each home has a different day-to-day routine. The following are a few different schedules that might work for you.

Remote Work Weekdays

For remote workers, a smaller midday setup may work. You may even want to get rid of your midday setting entirely. Instead, focus on saving money through late evening and overnight step-downs.

A School Schedule Household

If your family members attend school, set an early morning warm-up temperature. Then, use a stronger setback from mid-morning to mid-afternoon when everyone is away. Once your kids return home, set the temperature higher to ensure their comfort.

Someone Home All Day

Homes that have retirees, babies, or any other kind of caregiving needs likely need to stick to light setbacks only. Instead, you should focus on tiny reductions during periods of low activity and prioritize steady comfort.

Night Shift or Irregular Schedule

For these homes, build the schedule around your sleep blocks and not the clock. “Away” times should be determined by when you are actually away from home.

Smart Thermostat vs. Programmable vs Manual: What To Do Based on What You Have

To maximize your energy efficiency, keep the following tips in mind.

If You Have a Smart Thermostat

With smart thermostats, you can use gentle recovery and scheduling features. Try to avoid manual overrides because this can confuse your algorithm.

If You Have a Programmable Thermostat

For programmable thermostats, set up weekday and weekend programs. You can begin with simple blocks and adjust as you go.

If You Have a Basic Thermostat

With basic thermostats, the best option is to focus on your “Home” and “Sleep/Away” settings. Get used to changing the temperature at the same time each day so that it becomes a part of your day-to-day habits. For your long-term convenience and energy savings, consider upgrading to a smart or programmable thermostat.

The Biggest Mistakes That Kill Savings (And Comfort)

To ensure your comfort and energy efficiency, avoid these common mistakes.

• Making your morning miserable with huge setbacks
• Forgetting to set up weekend settings
• Weakening your system with blocked vents or dirty filters
• Keeping it at the same high temperature all day
• Cranking up your thermostat to catch back up following a setback.

When a Thermostat Schedule Won’t Fix the Problem

If you experience the following issues, you need to schedule professional repairs.

• One or more of your rooms won’t warm up because of a duct or airflow problem.
• Your HVAC system short cycles.
• No matter what you do, your home feels drafty because of duct leaks or insulation issues.
• Your furnace or heat pump is running nonstop.
• You have an older furnace that struggles to heat up your home after a setback.

Quick “Starter Schedule” Recap

For best results, adjust your thermostat slowly over 7 to 10 days until you get it just right. Additionally, remember to set a different weekend and weekday schedule based on when you are home, away, and asleep.

Stay Cozy This Winter

Before you make any drastic changes, start by adopting a realistic setback plan first. If this doesn’t improve the comfort of your home, call Fox Family Heating and Air Conditioning for a professional inspection.

FAQs

Should I turn the heat off when I’m gone?

You should not turn it off entirely. This can cause the heat to drop too much, making it harder for your furnace to catch up. Instead, set the temperature back a few degrees.

How big should a setback be so that it still feels comfortable?

A setback of 3°F to 5°F will allow you to save money while maintaining your comfort. If you feel comfortable at lower settings, you can save more money by adjusting your temperature by up to 10°F.

Is it bad for my furnace to recover from setbacks?

As long as the setback is moderate, it isn’t a problem. If you have a smart thermostat, your thermostat can also adapt to how long it takes to warm up to the new temperature.

Why does my house feel cold even when the thermostat says it’s warm?

This could be due to a draft, thermostat placement issues, humidity problems, or uneven heating. To determine and remedy the root cause, you’ll need to schedule an HVAC inspection.

Do weekends really need a different schedule?

In most cases, weekends require a different thermostat schedule. When you wake up, how long you are home, and when you go to bed can all change on weekends. Unless your schedule is exactly the same on the weekends and weekdays, you’ll likely need to adjust it.

When you’re in your back bedroom, the air feels like it is 62°F. However, your thermostat is clearly set to 72°F.

Before you panic about your heater dying, take a look at your ductwork. In many cases, this type of temperature difference is due to leaky ducts stealing warm air before it reaches every room.

How Your Heating System Is Supposed To Work

Normally, your furnace or heat pump creates warm air that is pushed through the supply ducts by the blower. This air reaches your rooms to provide warmth. Afterward, the return ducts bring air back into the system to be reheated.

If there are any duct leaks, this entire cycle falls apart. Instead of reaching your room, some of the warm air ends up in crawlspaces, basements, and attics.

What Duct Leakage Actually Is (And Why Winter Makes It Worse)

Over time, duct leaks can occur because of tiny gaps, aging duct seams, and loose connections. These holes allow warm air to escape. During the winter, the stack effect and pressure differences can exaggerate drafts and worsen the situation. As a result, your heating system may experience longer run times. You may notice weaker airflow in your farthest vents and an uneven comfort level.

The Sneaky Signs Your Ducts Might Be Leaking

Duct leaks often occur unnoticed. Pay attention to the following hidden signs you may be losing warm air through your ductwork.

• Some rooms warm up slower, especially the ones farther from your furnace.
• One or two vents have weak airflow, even if the filter is clean.
• Your rooms or vents are dustier than normal.
• One floor is constantly colder than another.
• When the heat is on, you hear a whistling, rattling, or fluttering sound in your walls or ceiling.
• Your energy bills have gone up without any obvious change.
• The rooms over your garage, near your exterior walls, or above crawlspaces are difficult to heat.

Why Do Duct Leaks Hit Some Rooms Harder Than Others?

There are a few reasons why duct leaks seem to affect some rooms more.

Distance and Duct Routing

When the run is longer, there are more opportunities for leaks, kinks, and lost airflow.

Ducts in Unconditioned Spaces

Unconditioned spaces, like attics, garages, and crawlspaces, get especially cold in the winter. When warm air leaks out of ducts into these areas, the warmth disappears quickly.

Pressure and “Path of Least Resistance”

Air always follows the path of least resistance. When there are leaks and loose connections involved, it can take airflow away from rooms that need it the most.

Return Air Problems: The Overlooked Half

While people often focus on supply vents and ducts, return ducts can also have issues. If they are blocked or undersized, the system will struggle to circulate air. As a result, you’ll experience cold spots in your home.

Common Ductwork Issues That Mimic “My Heater Is Weak”

It may seem like your heater is weak when the underlying cause is really ductwork issues.

• Disconnected or partially separated ducts are letting conditioned air escape.
• Inadequate insulation around the ducts is causing heat loss.
• A crushed or kinked flex duct is limiting your airflow.
• Poorly sealed joints at the elbows, plenums, or boots are letting air get out.
• Old, faulty tape and seal points are gradually breaking down.
• Leaky return pathways are bringing in air from the attic or crawlspace.

Drafts: When It’s Not Just a Window

While windows can cause drafts, you can also experience drafts from any kind of pressure imbalance. Duct leaks and returns can bring in air from unwanted areas. You may also feel cold air movement as the home tries to compensate for lost air.

What Homeowners Can Do Safely Before Calling a Pro

Before calling a professional for ductwork installation or repairs, try the following basic troubleshooting steps.

• Replace your air filter. Make sure it is the correct size.
• Check to make sure your supply and return vents are open and unblocked.
• Pay attention to when you feel cold rooms and weak vents. Note the time of day.
• Check for obviously disconnected duct sections in your attic or crawlspace without touching them.

Why Duct Leakage Matters Beyond Comfort

Duct leaks aren’t just a comfort issue. When heat escapes, it leads to wasted energy and higher wintertime energy bills. Because the unit must run for longer periods of time, it can lead to added wear.

In terms of comfort and air quality, duct leakage has a major impact. If the returns pull dusty air from your attic or crawlspace, it can negatively impact your indoor air quality. Often, the temperature and airflow will still feel off after you’ve adjusted them.

The Fix: What a Professional Duct Evaluation Typically Includes

If DIY troubleshooting doesn’t solve the problem, a professional duct evaluation can help. During the evaluation, our heating, ventilation, and air conditioning (HVAC) technicians will perform the following steps.

• Check the airflow and temperature in each room.
• Inspect the ducts for any signs of damage, leaks, and insulation problems.
• Seal problem spots on your ducts properly.
• Balance your home’s airflow.
• Recommend upgrades and repairs for your ductwork if they are genuinely needed.

Bring Comfort Back to Every Room

If certain rooms of your house feel unusually cold, your ductwork could be the hidden reason. With a professional duct inspection and sealing evaluation, you can make sure your home is prepared before the coldest stretch of winter hits.

For no-pressure advice and practical solutions, reach out to Fox Family Heating and Air Conditioning today.

FAQs

Can duct leaks really make one room cold and another warm?

Absolutely. The air has to travel to each run, so the farthest vents may have significantly less warm air because of the leaks.

Is duct sealing messy or disruptive?

Thanks to modern techniques like Aeroseal, duct sealing is a clean, quick process. Once the sealant has been blown into the system, we can quickly patch the injection point and remove our equipment.

How do I know if it’s the ducts or the furnace?

If your issue is due to the ductwork, the problems will typically occur in specific areas and not the whole system. For example, leaky ducts may cause one room to be unusually cold and drafty. However, the best way to know for sure is to get your system inspected by a licensed HVAC technician.

Do duct leaks affect indoor air quality?

Yes, they can. The change in pressure can cause air to be pulled into the system. Because the ductwork is in your attic, basement, or crawlspace, the air brings dust, mold, and other contaminants along with it.

Why is my upstairs colder in winter?

There are a few factors that can cause cold upstairs rooms in the winter. Heat rises, so warm air travels into your upstairs rooms and escapes through the roof. If the furnace isn’t powerful enough, it may not be able to push enough heat upstairs to replace the lost warmth. Depending on the underlying cause and your home’s setup, you may be able to remedy this issue through balancing or zoning.

Will closing vents help uneven heating?

Unfortunately, no. Closing vents will increase pressure and lead to increased wear on your home’s components. Over time, this can result in increased wear. If uneven heating is a consistent problem, the best option is to get professional balancing or zoning to fix the problem.

Gas furnaces are known for their powerful heat. With this heat, there is an added safety risk. Most furnace issues start small, so it’s important to get small problems fixed before they can escalate.

To enjoy good winter heating in Sacramento this year, pay attention to the following signs. If you notice anything that seems unsafe, immediately shut off your system and reach out for professional help.

How To Stay Safe: A Quick Disclaimer

As a homeowner, there are a few things you can do to troubleshoot.

• Listen, look, and smell for potential problems.
• Check to see if there is airflow.
• Replace your air filter.
• Test your smoke and carbon monoxide (CO) alarms.

To ensure your safety, avoid the following things.

• NEVER do anything with your gas lines, heat exchangers, vent pipes, wiring, or burners.
• NEVER open sealed compartments.
• NEVER do anything that involves more intensive tools than are needed for a standard filter door.

The 7 Things To Watch for During a Basic Gas Furnace Safety Check

To protect your home, furnace, and family, monitor your system for the following signs.

1. You Smell Gas or a “Rotten Egg” Odor

You may smell a gas odor near the furnace or gas meter, especially when the furnace initially starts. Because this may indicate incomplete combustion or a gas leak, it’s essential to leave the area and immediately call your gas utility or emergency services. Once a professional has declared the area safe, reach out to a heating, ventilation, and air conditioning (HVAC) technician for help.

2. You Hear the Carbon Monoxide Alarm or Notice CO-Type Symptoms

You may experience headaches, nausea, or dizziness that improve immediately after you go outside. If your CO alarm is working, you may hear it go off.

CO is odorless, so you can’t tell it’s present. If there is any hint of a CO leak, immediately make everyone go outside and call for emergency services.

3. There Is Soot, Scorching, or Discoloration Around the Furnace or Vent Area

You may notice singed insulation or browning around your cabinet or vent connections. This indicates potential issues with combustion, venting, or flame rollout. To stay safe, switch the system off at the thermostat and call for a furnace safety inspection.

4. You Noticed Weird Flame Behavior or Delayed Ignition

If you hear a rumbling, popping, or whooping noise on startup, it may be due to ignition or burner issues. These safety problems can also make the furnace hesitate before it lights. Because of the danger involved and the added stress on your system’s components, you should turn the furnace off and call a professional.

5. There Are Venting Red Flags You Can See Without Taking Anything Apart

Rattling pipes, water stains, rust, and indoor exhaust odors are all indications of venting problems. This can push combustion gases into your home, so it’s essential to shut off your furnace and call for help. Any active exhaust odor inside is an immediate emergency.

6. You Heard New, Unusual Noises

If you notice screeching, rattling, banging, persistent clicking, or grinding, it may be due to mechanical wear. This wear can lead to overheating, unexpected damage, and shutdowns. To avoid additional damage, you should turn off your furnace and schedule an HVAC inspection before you end up with a no-heat emergency.

7. You Saw Short Cycling, Weak Airflow, or Overheating Signs

Cold rooms, poor airflow from the vents, and short cycling may indicate airflow restriction, safety limit trips, and strain on the internal components. Additionally, an overheated furnace will shut down and blow cold air to cool off the hot components. As a result, you may feel cold air.

Start by checking the filter. Then, make sure your return vents are open and unblocked. If the problem continues, you’ll need to switch off the furnace and call a professional.

Sacramento-Specific Furnace Concerns: What To Watch Out For

Thanks to our unique environment, there are a few special issues you need to watch out for in Sacramento. In our area, dust and seasonal air quality problems can cause filters to fill up faster. As a result, this can cause airflow issues.

Additionally, many local furnaces are installed in closets and attics. Unfortunately, this means that stored items and insulation can be placed around them, leading to airflow and clearance problems.

To ensure your Sacramento home is ready for cold weather, remember to get a quick professional inspection before the first cold snap arrives.

When To Call for a Professional Safety Inspection

Immediately call for help if you notice the following symptoms.

• Gas odors
• CO alarms are going off
• Delayed ignition
• Loud booms when the furnace starts up
• Scorch marks or soot
• New, persistent noises
• Venting problems
• Short cycling
• Repeated shutdowns

FAQs

Is a burning smell normal when turning on a furnace for the first time?

As long as it lasts for just the first few minutes, it is a normal symptom. This just occurs because the dust in the furnace is burning off. However, call for help if the burning odor doesn’t go away.

How often should Sacramento homeowners schedule a furnace safety check?

We recommend getting your furnace checked each fall as part of your routine maintenance inspection.

What does a CO alarm mean if I don’t smell anything?

CO is odorless, tasteless, and colorless. Unless you hear an alarm or experience symptoms, you won’t even know it is there.

Why does my furnace make a loud boom when it starts?

This is called delayed ignition. It happens because gas is building up before it ignites, causing a mini-explosion. This is a major safety hazard and can be caused by multiple issues, so immediately schedule emergency repairs.

Can a dirty filter cause a furnace to shut off?

Absolutely. A dirty air filter can reduce airflow and cause your furnace to overheat. In turn, this causes it to automatically shut off.

Should I run my furnace if I see soot near it?

No. Soot means you may have a cracked heat exchanger or blocked vent. To ensure your safety, you should shut off the furnace and schedule HVAC repairs.

Each summer and fall, the wildfire smoke seems to be getting worse in Sacramento. Even when you’re hundreds of miles away from a wildfire, the smoke can infiltrate your home and end up stressing the HVAC system. Worse still, it can impact the health and well-being of your family.

At Fox Family Heating and Air Conditioning, our heating, ventilation, and air conditioning (HVAC) technicians are used to working in the local region. We understand the perils of Sacramento wildfire smoke and which HVAC solutions can alleviate the issue. By reaching out for more information about wildfire smoke and HVAC options, you can improve your indoor air quality (IAQ) and prevent smoke from damaging your existing unit.

How Wildfire Smoke Affects Your Home HVAC System

When wildfire season begins, it can take a toll on your home’s HVAC systems. As the fine smoke particles get inside, they can clog your unit’s air filters. This reduces the flow of air, resulting in higher energy usage.

Because your system has to work harder to cool your home, extra strain is placed on the blower motors and coils. Over time, this increases the likelihood of unexpected breakdowns, repairs, and replacements.

In Sacramento, there are more days with high air quality index (AQI) readings. Recurring regional smoke and long-duration wildfires mean that IAQ issues are more than a minor problem. Without the right HVAC filters for wildfire smoke, your family can experience increased allergy and asthma problems. Even when your windows are closed, you may smell the odor of smoke and experience poor air quality.

Understanding MERV Ratings and Why They Matter During Smoke Events

The minimum efficiency reporting value (MERV) is a metric that represents how effective filters are at removing particles from the air. A higher MERV rating means the filter can remove smaller particles from the air. For example, the following are the particulate sizes you can expect for some of the most common MERV ratings.

• MERV 8: This level is ideal for removing dust and pollen. It is not effective for smoke particles.
• MERV 11: With a MERV 11, you can capture smaller particles. This is a good starting point for your home.
• MERV 13: This level is the recommended option for wildfire smoke. It can capture particles as small as one to three microns, making it ideal for smoke.

Before you get a MERV-rated filter, you should always check to see if your system is compatible. Higher filtration restricts airflow, which can impact your HVAC performance if your unit isn’t rated for the higher level. Because of this, you should always read through the manufacturer’s guide or talk to an HVAC expert before upgrading your MERV filter.

What Type of HVAC Filter Works Best for Wildfire Smoke?

When it comes to protecting home air quality from wildfires, there are different levels of filtration. Besides considering the MERV rating during wildfire season, you should see what type of filtration works with your system, the cost, and potential drawbacks.

Pleated High-MERV Filters

Pleated high-MERV filters are known as the best HVAC filter for smoke for a few key reasons. They are the most practical solution because you don’t have to install anything extra. All you have to do is switch out your existing filter. Once installed, a high-MERV filter offers an excellent balance of performance and system compatibility.

You should always check with your manufacturer’s guide to see what the maximum MERV rating is for your unit. MERV filters cause increased airflow resistance, which causes your HVAC system to work more and can lead to higher energy bills.

HEPA Filtration

HEPA filtration is an add-on solution for existing HVAC installations. Basically, a whole-home HEPA bypass system is installed that filters your home’s air alongside your HVAC system.

When it comes to disadvantages, homeowners need to remember that HEPA filters need to be replaced frequently and are ineffective for volatile organic compounds (VOCs). Additionally, they can restrict airflow in your HVAC system.

Activated Carbon Filters

When considering Sacramento wildfire smoke and HVAC upgrades, it’s also a good idea to consider an activated carbon filter. These filters are excellent at reducing foul odors and the concentration of VOCs in the air. Activated carbon has a large surface area and is considered a porous material, so it can absorb odors.

However, it’s also worth noting that they are less effective at reducing pollen, dander, and other allergens from the air. They also tend to be more expensive than standard filters.

Electronic Air Cleaners

Electronic air cleaners are a good option for collecting finer particles, dander, and allergens. They are also known for being quite cost-effective.

These units require frequent maintenance and don’t remove odors. Some electronic air cleaners can produce ozone, which can negatively impact your respiratory health. Before installing this option, check to see if it creates ozone.

How Often Should You Change Filters During Wildfire Season?

Besides deciding on solutions to wildfire smoke and HVAC upgrades, there are a few other things you can do to improve your indoor air quality. Normally, we recommend changing air filters every 30 to 90 days. However, during periods of heavy smoke, this frequency should be shortened to between two and four weeks. When smoke levels are extreme, you may even need to change it every one to two weeks.

You may need a filter change if you notice any of the following symptoms.

• Decreased airflow
• Longer HVAC run times
• Increased indoor smoke smell
• Dust buildup around your vents

Should You Run Your HVAC System During Wildfire Smoke Events?

This is a common misconception. While it makes sense to worry about the impact of indoor air quality and wildfire smoke on your HVAC system, your HVAC unit is necessary for ensuring safe, clean air for your family. To protect your family and your HVAC system, you should use recirculation mode. This reduces the amount of smoke that the HVAC unit has to process.

Besides using recirculation mode, you should keep your windows and doors closed. Don’t use swamp coolers, whole-house fans, or attic fans because these systems introduce outdoor air into your home. Unless you have an advanced circulation system, you should avoid using outdoor air as much as possible.

Indoor Air Quality (IAQ) Solutions for Wildfire Smoke

When it comes to indoor air quality and wildfire smoke, investing in the right IAQ systems will greatly impact the health and well-being of your family. High-quality IAQ solutions can reduce smoke particles, allergens, and dust, so your family experiences fewer allergy symptoms. Because of all of these factors, IAQ solutions can improve your family’s breathing and lead to better respiratory health.

DIY Steps Homeowners Can Take To Improve IAQ During Smoke Events

If you want to improve your IAQ during smoke events, try using the following simple steps.

• Instead of having your HVAC constantly on, switch it to “auto” mode.
• Seal gaps around your doors and windows to prevent smoke from getting in.
• Replace your air filters more frequently. During the worst periods of wildfire smoke, you may need to do it every one to two weeks.
• Make sure your indoor surfaces are free of dust.
• Set up portable HEPA purifiers in your bedrooms, so your family can breathe easy at night.
• Avoid using candles, incense, or other indoor air pollutants during major smoke events.

When To Call a Professional HVAC Technician

If you’re dealing with wildfire smoke and HVAC issues, there are a few important signs that you may need to reach out for professional help.

• Your system’s airflow dropped significantly.
• It constantly smells like smoke indoors.
• Your vents and coils have accumulated a lot of sun-blocking soot.
• The air filter clogs quickly after you replace it.
• You want to learn more about getting a HEPA filtration or high-MERV upgrade.

Whether you want to learn about air purifiers vs. HVAC filtration for smoke or simply need a tune-up, Fox Family Heating and Air Conditioning can ensure your home is ready for wildfire season.

Looking for cleaner indoor air this wildfire season? When it comes to navigating Sacramento wildfire smoke and HVAC solutions, Fox Family Heating and Air Conditioning is here to help. Call today for help boosting your HVAC airflow, determining the right air filter, and installing IAQ upgrades.

Your heat is on, and you can feel the air flowing through your vents. Instead of a toasty warmth, your home is struggling to heat up, and dust appears to be everywhere.

In this situation, many people will reach for the highest-rated air filter without thinking about their airflow. To balance clean air and good airflow, you need an air filter that suits your comfort goals and system.

Why Filters Matter More During Heating Season

Because your system works overtime during the winter, your filters get dirty faster than normal. If the filter is clogged or excessively restrictive, it can make your heat feel weak and uneven. Instead, it’s important to get a filter that offers a balance of comfort and healthy air without straining your furnace.

Quick Basics: What an HVAC Filter Actually Does (And What It Does Not)

Your heating, ventilation, and air conditioning (HVAC) filter is designed to trap particles, such as pet dander, lint, and dust. Depending on the filter’s rating, it can even trap smoke, allergens, and fine particles.

However, filters won’t remove every odor from your home or resolve all of your airflow issues. They also won’t remedy humidity problems. Instead, filters are essentially one piece of the larger picture.

The Main Tradeoff: Air Quality vs. Airflow

When picking an air filter, there is a key tradeoff between airflow and filtration. A higher filtration level will catch smaller particles, but it will also create added resistance if the system isn’t made to handle it. For the best results, you need a balance that your HVAC system is able to efficiently handle.

Understanding MERV Without the Headache

What MERV Means: The minimum efficiency reporting value (MERV) represents how well a filter can capture particles. A higher MERV means it can filter out smaller particles.

A Practical Way To Think About It

• Lower MERV: A low MERV will offer better airflow in exchange for basic dust control.
• Medium MERV: This type of rating is a good balance between airflow and dust control.
• High MERV: While a high MERV can capture the finest particles, it may also restrict airflow. This is more likely to be a problem in older systems.

Fast Guidance

A general rule of thumb is to start with a mid-range MERV as long as the filter fits and is changed on time. If you try to jump to a high MERV and the airflow suddenly drops, it can negatively impact your comfort.

Start Here: 3 Questions That Pick the Right Filter Faster

• Does anyone in your home suffer from allergies, asthma, or smoke sensitivity?
• Do you have pets or heavy dust?
• Does your home have whistling at the return registers, weak airflow, or rooms that warm up slowly?

Filter Thickness Matters More Than Most People Realize

The MERV rating isn’t the only factor to consider. Filter thickness also has a major impact. A 1-inch filter is a common, affordable option, but it can load up quickly. If it is too tight, it can result in restricted airflow.

Some HVAC systems are able to handle thicker filters. These offer more surface area, which is better for longevity. Over time, these filters are often better for airflow.

However, you can’t use a filter that is the wrong thickness for your system. Always check your system specifications before you install a new filter.

Common Filter Types and When They Make Sense

When you shop for filters, you’ll generally be able to find the following types at most stores.

Fiberglass: Flat and Cheap

Fiberglass filters are incredibly affordable and offer low resistance. However, they offer the least air cleaning.

Pleated Filters: The Most Common “Upgrade”

With pleated filters, you can enjoy better particle capture for a good value. However, this upgrade can restrict airflow if you get a MERV rating that is too high for your system.

High-Performance Allergy Filters

A high-performance allergy filter offers the best fine-particle capture. Depending on the setup and how frequently you change it, this can lead to potential airflow problems.

A Simple “Pick Your Filter” Guide Based on Household Needs

Each household is different, so consider the following factors as you pick a filter.

If Comfort and Airflow Are the Priority

A balanced filter won’t restrict airflow. For best results, make sure to change it regularly throughout the winter.

If Allergies Are the Priority

For allergy sufferers, better filtration is essential. However, you don’t want it to be too restrictive because this can impact airflow. Additionally, make sure to replace it regularly and get the right fit.

If Pets Are the Priority

A pleated filter is great for pets, but you need to replace it consistently. To reduce dander and pet hair, it’s a good idea to brush pets regularly and clean the return vents.

If You Worry About Smoke and Fine Particles

High MERV ratings are effective for fine particles, but your system has to have the capacity to handle the higher level. Otherwise, it can strain your furnace and result in more frequent repairs. In some cases, the best option may be to invest in whole-home filtration add-ons instead of raising the MERV rating and pushing your HVAC system too much.

How To Choose the Correct Size and Avoid Air Bypass

To get the right air filter, remember the following important tips.

• Check your old filter size.
• Make sure the filter fits in the slot. An overly small one can leave gaps that let dirty air through.
• If your filter rattles, bows, or doesn’t sit quite right, it won’t be able to do its job well.

Warning Signs Your Filter Is Starving Airflow

If you experience any of the following signs, your filter may be starving the airflow to your system.

• You noticed weak airflow from your vents right after a filter change.
• Your furnace runs longer, but your comfort level doesn’t improve.
• There are whistling sounds coming from your return grille or filter slot.
• Rooms that are far from the furnace feel colder than the rest.
• The filter gets dirty unusually fast, such as within two to four weeks.

Replacement Timing for Winter: Don’t Wait for It To Look Dirty

During the heating season, you typically need to change your filter more often than you do during the spring or fall. To stay on top of filter changes, check it monthly. Then, replace it based on dust buildup and your comfort. If your home has pets, heavy heating usage, or remodeling dust, you should replace it more frequently.

Small Habits That Help Your Filter Work Better

You can help your filters do their job by vacuuming high-dust areas and around the returns. Make sure the return grilles are not blocked by curtains, rugs, or furniture.

To ensure proper airflow and no pressurization issues, all of the supply vents should be kept open. Additionally, keep the doors to each room open.

When To Call a Pro Instead of Fighting With Filters

If your filter seems to be causing airflow issues or the heat level is uneven, you should schedule professional repairs. Similarly, unusual noises, short cycling, and overheating are signs to call an HVAC expert.

FAQs

Is a higher MERV always better?

Not always. While a higher MERV is better at filtering the air, it depends on your goals. For example, MERV 11 is generally fine for allergies. If you have an older heat pump or furnace, higher MERV ratings can also strain the system. Because of this, you should always check to see what the highest MERV rating you are allowed to use on your HVAC system is.

How often should I change my filter in winter?

Each manufacturer has different specifications. Generally, you should change your filter every 30 to 90 days. However, it should be replaced more frequently during periods of peak use.

What if my filter size is hard to find?

Many companies, such as big box retailers, sell filters online and will ship them to your house. Some units also use filters that are cleaned instead of replaced, so you don’t have to constantly search for new filters.

Can a dirty filter damage my furnace?

Absolutely. Filters are there to protect your furnace. If it is dirty, the debris can get inside your HVAC equipment and cause it to overheat. Over time, it will strain your blower motor and lead to more frequent repairs.

When the weather is chilly and Santa Ana winds are blowing, you don’t want to deal with a furnace that won’t start. There are many different reasons why a furnace could malfunction, which is why a proper diagnosis is important.

To ensure the safety and comfort of your family, you need the help of a professional heating, ventilation, and air conditioning (HVAC) technician. At Fox Family Heating & Air Conditioning, our leading HVAC experts can help you determine why your furnace isn’t working and the necessary steps for fixing it.

Common Reasons a Furnace Won’t Start

As a homeowner, it can be challenging to figure out why a furnace is not turning on. There can be multiple reasons for this malfunction, which is why a professional HVAC inspection is essential. In most cases, furnaces won’t start due to one of the following issues.

• Thermostat Settings: If your thermostat is set to “cool” or “fan only,” you won’t feel any heat. Additionally, a malfunctioning thermostat may be unable to trigger the heat to turn on.
• Dead Batteries: When the batteries are dead in your thermostat, it stops the thermostat from turning the furnace on.
• Clogged Air Filters: Sometimes, air filters can become so clogged that the furnace overheats. When this happens, the furnace automatically switches off to protect the furnace and your home from potential harm.
• Tripped Breakers: Breakers trip as a safety mechanism. Once they are switched off, electricity can’t flow through the wiring to your furnace.
• Dirty Flame Sensors: If the burner flame sensor is dirty or not working properly, it won’t be able to sense when the burner is lit. When this happens, it will automatically trigger the system to shut off.
• Safety Switch Triggered: Any time a pressure or limit switch is triggered, it can result in your furnace shutting off. Because this indicates that there is an underlying safety problem, you should always call an HVAC technician for furnace maintenance.
• Gas Supply Issues: If a gas furnace won’t start, it may be due to problems with the gas supply. This is another potentially dangerous issue, so schedule a professional HVAC inspection right away.
• Unit Age or Component Wear: As furnaces age, they become less efficient and components can wear down. Eventually, this can lead to problems starting and other performance-related issues.

DIY Checks You Can Safely Try

So, why won’t my furnace turn on? If you don’t hear your furnace switch on, there are a few common reasons why. The following furnace troubleshooting steps can help you figure out the source of the problem. For more advanced furnace repairs, you should always reach out for professional help.

Check the Thermostat

If your furnace won’t kick on, start by checking the thermostat. Make sure it is in “heat” mode. Then, increase the temperature so that it is higher than your current room temperature. This should trigger the furnace to kick on. If it doesn’t, you should also try replacing the batteries.

Check the Furnace Switch & Breaker

Next, you can try troubleshooting your furnace switch. Start by locating the furnace switch, which is often on the side of the furnace. It should be in the “on” position. You should also check the breaker panel and reset tripped breakers.

Check Your Air Filter

Clogged air filters can prevent airflow and cause your unit to overheat. Once this happens, the furnace will shut off as a safety mechanism.

Fortunately, you can easily prevent this problem by cleaning or replacing your air filter. Most manufacturers recommend changing the air filter every 30 to 90 days. However, filter changes should be done more often during periods of peak usage.

Make Sure the Furnace Door Is Closed

If the furnace door is open, the safety switch can prevent it from starting. To troubleshoot this issue, close the furnace door.

Check the Pilot Light

If your furnace has a pilot light, a faulty pilot light can prevent your furnace from starting. To check for this problem, find and observe the pilot light. It should have a steady, blue flame. If the flame is yellow or flickering, this indicates incomplete combustion.

Relighting the pilot light and troubleshooting pilot light issues aren’t DIY tasks. When the pilot light is responsible for your furnace problems, you should always reach out for expert help.

Look for Error Codes

Your furnace’s manual or the diagnostic code table on the control panel should list what blinking lights mean. While different blink quantities represent different problems according to each brand, the following are the most common meanings.

• 1 Flash: Ignition-related problems
• 2 Flashes: Pressure switch stuck closed
• 3 Flashes: Pressure switch stuck open
• 4 Flashes: Open high limit
• 5 Flashes: Flame sensor issues

Warning: DIY Checks You Should Avoid

When a heater won’t start, there are a few DIY checks you can do to narrow down the source of the malfunction. If the previous troubleshooting steps are ineffective, do not try to repair your furnace on your own. HVAC systems are extremely complex, so DIY repairs can lead to physical dangers to yourself and your unit.

You should never do any of the following repairs on your own.

• Opening any gas components or lines
• Removing or cleaning the flame sensor
• Repairing, replacing, or updating any wiring
• Resetting limit switches
• Working on capacitors
• Disassembling interior components

Trying to perform these tasks on your own can lead to gas leaks, electric shocks, carbon monoxide poisoning, and damaged HVAC components. Rather than risk these potential issues, give Fox Family a call for help with all of your furnace replacements and repairs.

When To Call a Professional HVAC Technician

At Fox Family Heating and Air Conditioning, we have years of experience in helping residents with all of their HVAC installations and repairs. While there are some problems you can handle on your own, there are situations where delayed repairs can risk the safety, health, and well-being of your home and family. The following are some of the major red flags that indicate your furnace requires professional help.

• Furnace Keeps Cycling But Never Starts: Often, this problem is related to the control board or ignition system. These are both tasks that are best left to the experts.
• Repeated Breaker Trips: A breaker might trip once because of a random power fluctuation. If the same breaker trips repeatedly, there is an underlying issue with your electrical system that needs to be repaired.
• Gas Smells: Gas odors are an immediate danger to yourself and your family. As soon as you smell gas, switch off the furnace and exit your home. Then, call your gas utility provider for help. The utility provider can switch off the gas to prevent a fire, gas poisoning, or explosion. Afterward, one of our HVAC technicians can inspect your furnace and determine the underlying cause of the problem.
• Error Codes Persist: Understanding the manufacturer’s error codes requires specialized knowledge, equipment, and skills.
• Furnace is 12 to 15 Years Old: Once your furnace is 12 to 15 years old or older, it is more likely to break down. It also becomes less efficient, so your energy bills will increase. To save money over the long run, the best option is to get a new furnace installation.
• DIY Checks Didn’t Work: If your DIY troubleshooting tips didn’t fix the problem, a serious issue is likely at fault. To remedy the problem, you need to reach out for professional help.
