Superior HVAC was very quick and efficient when diagnosing my old furnace this winter. Our gas valve gave out and there were able to replace it and get it running again the same day!

Our airflow was awful in our house. I called Superior HVAC Service and they showed up within 3 hours and performed a full duct cleaning and balanced airflow through each vent. The house feels evenly heated for the first time this winter. Ryan was also very helpful in showing us ways to reduce our duct blockage !
