Quality Air Conditioning, Heating, and Refrigeration Solutions for Irving area homes and businesses since 1975. Founded by brothers, Mark and Kent Ellis, Ellis Air Conditioning & Heating began in 1975 with one truck and one vision - to provide the area with the best service in the industry. Now, over 40 years later, hardly a day goes by that you don't see a big white truck with "ELLIS AIR" on the side, driving by on its way to another service call.
