First of all, my problem was big and was told it would be expensive. So, I asked around and was told to give Dave a call. I got a quick response and Dave called back to discuss my problem. He gave me several options and recommendations also gave me payment options. What I liked the most is that I called him back with a question and he was willing to return and explain the specifics of the system. Very friendly and prompt attention ........definitely recommend them to anyone needing A/C work.
