Superior HVAC fixed an issue with our air conditioner that was blowing warm air. The technician replaced a failed capacitor and the system was cooling properly before he left

The furnace would start but shut down after a few minutes. The technician replaced a faulty limit switch and confirmed everything was operating safely

Our tankless waterheater needed fixing. We called in the morning for service and a technician arrived within a few hours. It was a very quick response. Curtis was very friendly and informative. He explained everything in detail and answered all questions we had. We are very satisfied and would recommend!
