I'm a first-time homeowner in Georgia, and I'm trying to get a grip on how often my AC should be running. Right now, I've set it to cool to 74°F during the day and 71°F at night. I just raised the daytime temp to 75°F since I figured the difference would be hardly noticeable. I took a look at my AC run time lately and I'm wondering if this is typical or if it suggests a possible issue. Any insights based on my temperatures and conditions?

From what I've gathered, if your AC is sized correctly for your home, it's normal for it to run throughout the day. The key is whether it cycles on and off frequently. If it does that, it might not be the right size for your space. And yes, humidity definitely makes a big difference—higher humidity means your AC works harder to cool the air and reduce moisture.
Honestly, run time isn’t the best way to gauge your AC’s efficiency. Compare your power bills to similar houses in your area if you can. That’ll give you a better idea of whether your system is working as it should or if there's a problem.
The heat in the Southeast has been intense lately, more than usual. Also, if you have high ceilings, it can be tricky to cool those spaces effectively. Consider adding a ceiling fan in that room; it might help circulate the air better. By the way, I’d probably find it chilling at 71°F; raising it a couple degrees might make it more comfortable without stressing the AC too much!
Yeah, I think 71°F is a bit much for me too! I’ll try bumping it up a bit and see how it goes.

Thanks for the tip! I’ll definitely look into my power consumption. Just trying to make sure everything's working as it should.
