How Long Should It Take To Cool Down My House With Central Air?
Dave Henry Explains in this videos
How long does it take to take a house to cool down from 80 degrees to 75 degrees?
There are a couple of different variables. One is that it depends on how hot it is outside.
Obviously If it’s a 100 degree day its going to take longer to cool down vs if it’s a 85 to 90 degree day. Air conditioner units will run longer and harder on very hot days then on cooler, not so humid days.
But you are looking typically anywhere between 4-6 hours to cool a house down if it got up to a high temperature.
