Outstanding Service!I had a concern with my AC unit, and Superior HVAC did not disappoint. Sarah was prompt, courteous, and fixed the issue in no time. She even took the time to clean the unit and check for any potential future issues. I couldn’t be happier with the service I received.

My furnace suddenly stopped working, so I called Superior HVAC Service for help. Hunter arrived quickly, found the issue right away, and had it repaired in no time. He also checked my water heater before leaving to make sure everything was running efficiently. The whole process was smooth, and I’m really happy with the service!

Ian did a fantastic job diagnosing and replacing the gas valve on my water heater. He explained the whole process, and the pricing was very reasonable for the quality of work.
