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

Facing a furnace issue, I contacted Superior HVAC Service, and Tanner proved to be responsible, responsive, and highly skilled. He arrived promptly, explained the problem and his actions, and provided professional insights. Tanner's professionalism and thorough explanation of charges and future maintenance tips impressed me, making Superior HVAC Service my go-to for HVAC issues.

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.

Had an issue with our central HVAC at home, called early in the morning, someone picked up the phone and was able to schedule an appointment same day. Brian showed up at the house, was professional and courteous to show me what our problems were and provided solutions/suggestions to fix. Thank you!
