I had a great experience with Superior HVAC ! Ian diagnosed the problem with my furnace immediately, explained every step of the repair, and had it running perfectly in no time. The service was top-notch, and their pricing was very reasonable. I’ll definitely be calling them again. Huge thanks to the team!

My water heater wasn't working. Set the appointment the next day and they found the issue. Changed a new water heater the same day. Very friendly, good communication and also very helpful. Service was 5 of 5.
