They came out with in a couple of hours of calling them. They were very nice people and I really liked them, but they did not fix my problem. My AC was making this rumbling noise that I have never heard before, they said that was normal and the noise was coming from outside. But the noise just kept getting worse, and it is not coming from outside, it is coming from inside. At thanksgiving running the heater everyone kept asking what is wrong. So I don't run it, and staying warm with space heaters. Trying to get someone to come look at it now. like I said they were very nice people, but at 172.00 later it still is not fixed. don't know if I should call them. cause something is definitely wrong. Thank you for listening to me. Arlene read more
