I called Rocky Top after another company had failed to determine why my A/C quit. (They checked the outside unit and said the compressor was going bad.) Manny arrived, checked the outside unit and the inside unit located in the attic. He found the overflow pan was full causing the unit to stop. After many trips up and down the stairs, he cleared the drain pipe and the unit works fine. Through it all, he was respectful of my house, wearing shoe covers to keep my carpet clean, answering my questions, and explaining what he found. I will have to purchase a new unit within the next year due to the age of the existing on and Rocky Top will be the company I call!
