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.

My elderly mother's furnace went out on a cold night. Superior HVAC Service prioritized her call and got someone out there within an hour. Mark was incredibly kind and patient, and he got the furnace working again quickly. I can't thank them enough!

My water heater suddenly stopped working so I called Superior HVAC Service. Alvin arrived right on time, fixed it quickly and did a great job. He also checked my heater to make sure everything was working smoothly. The whole job was flawless and I would definitely use them again!
