Condo AC not working
My condo switched the ac on about a week ago in the building. The temperature will not drop below 26 even though I set it to 20. It is blowing air but not cold air. Seems to be running like a fan. My thermostat is set to cool and auto. I have tried turning the power on and off to reset it. I have changed the filter too. Nothing seems to be working. I have attached a picture of the model. I have asked the building manager and only my unit along with 2 others are having this issue. Any thoughts as to what it could be? Thanks for your help in advance!
