Ryan from Superior HVAC Service replaced our old thermostat with a new digital model. He programmed it and explained all the settings. Everything works exactly as promised. Won’t hesitate to call again!

Our furnace was noticeably slowing down. Superior HVAC Service ran a combustion analysis on our gas furnace. He adjusted the air-to-fuel ratio and optimized performance. It runs better than it has in years.
