Moving from Illinois and in need of a good tune up service for my heat pump system I heard the radio ad of Shumate and decided to give them a call. I am extremely glad I did. The tech John was very through in his examination and explanation of the needs of my system. In my experience with other HVAC companies,i can say Shumate Mechanical was exceptional. Please know I would refer this company to all of my friends. Thanks again, Fred Clark Athens.
