My AC is set to 77F and the thermostat reaches that temperature but the AC keeps running. What could be the causes for this? This is in connection with this post How long should it take to a 1.5 tons AC to cool down a 2000sqf house from 80F to 77F? where you can read a lot of details regarding my AC
Edit: If I set the AC to 80F then it goes on and off every 10 minutes. It can possible be air leaking to this degree.
