On a cold winter day, my furnace died of old age. I happened to stumble upon Superior HVAC Service and the next morning, a technician was at my place! The level of professionalism from the first call to the final cleanup was impeccable. I’m very pleased with the furnace installation experience I’ve had!

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

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.

Matt, our installer from Superior HVAC Service, was professional, conscientious, friendly, and knowledgeable during the installation. This isn't the first time we've worked with them, and their consistent quality work and punctuality make them a preferred choice. Every employee we've interacted with has been great.
