Professional and efficient tech guy named George. The unit had an error code—turned out to be a sensor issue. Fixed quickly and working better than before. Will recommend Superior HVAC and services

These guys really know their stuff! Our furnace went down earlier in the week and our house was freezing! George was able to come and asses right away, and provided solutions that worked well for our family and budget. I highly recommend Superior Heating and Air Conditioning!

Our gas fireplace wouldn't light. Superior HVAC Service sent Maria, who quickly cleaned the pilot light and got it working again. She was friendly, efficient, and charged a very reasonable fee. Highly recommend!

The two technicians were very friendly, informative and professional as they diligently installed our new AC unit. They left a very clean workspace and tested the unit before leaving. Very happy with this service!
