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.

I want to express my very positive feedback about Superior HVAC Service. They installed a new furnace, air conditioner and water heater. I've never regretted choosing Superior HVAC Service because they respond promptly to my calls and their personalized service is truly valuable. I often recommend them to others.
