AIR CONDITIONERS HAVE A LIMIT ON HOW MUCH THEY CAN COOL ON EXTREMELY HOT DAYS. Air conditioners by design can not make a house colder than roughly 15 or 20 degrees below the outdoor temperature.

There are a lot of mechanics, thermodynamics and other sciences behind why this is which you can look up if you’re interested. The best course of action when it’s a million degrees outside and your unit is running but not catching up is to wait until later in the day when temperature drops to see if the house starts getting cooler. If it doesn’t, then give us a call. If it does, you just saved yourself a service call.
