We finally repaired our old heat pump and we are very pleased with their work. The technicians were friendly, respectful and professional. We are very happy that we now have a more efficient heater, the unit is working great. I would definitely recommend Superior HVAC Service!

We noticed that the boiler was leaking a few weeks ago, so we had to call for help from an excellent hvac service.

The technician came to our house immediately after the call, diagnosed the unit and scheduled the repair by the end of the day. This was a very timely post.

They saved me tons of time and effort! I originally planned to conduct my AC repair on my own, but my friend recommended that I hire instead of them. It was quite efficient and incredibly rapid. Thanks!

If the hot water heater's pilot light goes out, Leo explained how to re-start it. This is a great company.

I was not happy with a service call I had and was issued a full refund by the manager so I changed my review to 5 star. The tech was professional but did not have the proper tools to diagnose my issue. It happens, and the company did issue a refund.
