I had a problem with my air conditioner so I called The Lee Thompson Company. They sent their tech out and he really knew what he was doing. He found the problem relatively quickly, and he replaced a relay switch in the controller board so I could have cool air until the replacement part came in. When the new part did arrive, he came back out quickly to install it for me. I was impressed by how professional they were, and also by how easy they were to get along with! Very nice people!
