Is it OK for AC to run all day?

Here’s the thing: It’s normal for your AC to run continuously during hot summer months. You see, on extremely hot days—we’re talkin’ high 90s to 100s—your system needs to keep up with the incoming heat. To do that, it will run longer in order to maintain a constant, desired temperature in your home.

Why can’t I set my thermostat below 70?

“Do not run the AC unit below 70 degrees indoors for the same reasons — it can freeze the evaporator coil,” he says. With some systems, that threshold might be 65 or 68 degrees.
