Maintenance on my tankless water heater went perfectly with Superior HVAC Heating and AirConditioning. The technician named Sean was thorough and ensured the system worked optimally. Excellent customer service and professionalism.

My furnace died during the night and my house was completely cold. Daniel was the service technician who gave me the bad news that my furnace had to be replaced. He went above and beyond to get me the installation the same day. (The installation was done quickly and professionally.) Daniel and the installers were professional, compassionate and very helpful. I wouldhighly recommend him and this company.

When my furnace started blowing cold air, I reached out to Superior HVAC Service. Ian arrived right on time, explained the issue clearly, and got straight to work. In no time, the heat was back, and he even took a moment to inspect my boiler. Definitely a company I鈥檒l trust for future HVAC needs!
