HVAC companies like ours startup because we are passionate about helping people when it gets hot (or cold) outside. We honestly want to get you comfortable as soon as your AC breaks down. Some people want their home to feel like a meat locker, but the reality is your system can only get your home so cool.
Your system is designed to cool your house 18 to 22 degrees less than the temperature of the house at any given time. Meaning, if your house is currently 80 degrees, the temperature of the air coming out of your registers should be 62 to 58 degrees. As the temperature of the house comes down to your desired 72 degrees, the temps coming from the supply registers will be 54 to 50 degrees.
Your house can get cooler than that. Most of the time, I sleep with the temperature in my bedroom at 68 degrees. I can only do that if I strategically set my thermostat not to let my house get too warm during the day. If you let your house get to warm, say 85 to 90 degrees, before turning your system on, your AC will struggle to bring the temps in your home to 72 degrees or less.
A system is designed to cool your house one or two degrees every 15 minutes. But if it’s super-hot in your home, the walls are going to be warm, the furniture is warm, and the ceiling is warm. All the items in your house will need to cool down before you’re going to start feeling comfortable again. So if it’s 90 degrees in your home before you decide to turn your AC on, it may have to run all through the night, even into the following day to get you there, depending on the age of your HVAC system.
So, the answer to the question is about 72 degrees. 75 is reasonable for every home, but some systems are old and inefficient. Some systems aren’t sized large enough for that particular home. Every house is different. Some systems might be low on refrigerant. It could be a variety of things.
