Ok last night here in Texas it was warm so i had the AC on most of the night. I woke up freezing and turned it off. Today around noon it got real muggy outside and I turned on the AC again. I noticed shortly after that it wasn't cold air just air. I stuck my head outside and noticed that the outside unit was not on or making any noise. the insdie part was on making noise blowing air. What could be the problem. I checked and made sure it's not frozen up and it's not the breaker. My house is about 21 years old and i've never had work done on the ac unit just cleaned professionaly but not for at least a year and a half.
