Filter is clean, have left it powered off for hours, and tried different settings but nothing has changed.
Current situation: When set to Hi Cool and "Coolest" on the temperature dial, the compressor kicks on and I can feel the cool air blow for a few minutes. Then the compressor turns off and I can feel HOT (not just uncooled) air coming out. That stays for a little bit then there is "normal" temperature air coming out. I hope that makes any sense.
Last few months: We had a heat wave a little while ago and my AC was still blowing cold but it couldn't cool off any more than just the path of the fan. I put in a maintenance request and got a response that it was because of the heatwave which I didn't doubt. A couple weeks later, we had another softer heat wave and the same thing happened. I put in the maintenance request and they came out to check it and said it was blowing in the 40s. Last thing I remember changing was the power going out while I was out of the house and the AC was running. So it probably kicked on right when the power came back on.
