I thought the freon was just low. Thats wasnt the problem! The air was cold then the it just started blowing out hot air. Then it would get cold again. I repeatedly had freon in it but it did not fix the problem. I am a disabled person that has many doctor visits in cities that range from 50-100 miles away and the summer is especially tough on me. The meds I take make it hard to regulate body temp and its NOT PLEASANT at all!!!
