We recently upgraded to a heat pump installation in Ontario and chose Superior HVAC. They answered all our questions and handled the install professionally. The system is quiet and efficient. Very satisfied.

the air handler quit during the hottest week of July. They found a weak capacitor, replaced it, cleaned the coil, and wiped the unit down. Out Superior membership plan covered most of the visit, and we were bumped up the priority list automatically. He was quick but careful, which is rare
