Central A/C stopped working Thursday night. Contacted Superior Friday morning and sent a technician within a few hours. They confirmed the worst but were able to install a brand new one the next day. The technicians were professional and courtious. Excellent service! I would recommend them any day!

Superior HVAC, Heating and Air Conditioning has a great team, with fast, friendly, and fair service. Tyler, the technician, fixed my ignition issue in under an hour and even took the time to check my thermostat before leaving.
