Quality Air Conditioning, Heating, and Refrigeration Solutions 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. The brothers recall, “It wasn’t easy in the beginning, but like all small businesses, it takes perseverance – and our parents made sure we had plenty of that. We know now how lucky we were to have their support. There have been some real changes around here since then – it has been great to be a part of the growth.” This growth has resulted in Ellis Air Conditioning and Heating becoming one of the leading and most sought after HVAC companies in the Dallas/ Ft. Worth metroplex.
