What do y'all set your temp at on your AC for the summer? I usually have mine between 72-74. Alot of people I know says they keep theirs at like 68-69. My unit would for real never shut off if I kept it there. Right now at 73 it runs for a couple hours before shutting off. I honestly think there is something wrong with it. It does feel that cool at all. I set a house thermometer on top of our vents and it shows 59 and I have the temp set at 73 most days, I've read the air should be 20-25 degrees lower blowing from vents than the unit it set at. I don't know, what's your set at?
