Our furnace suddenly stopped blowing warm air, and we were freezing! Conner quickly diagnosed the issue as a bad blower motor and had it replaced the same day. He explained everything in simple terms and even checked the rest of the system to make sure we wouldn’t have more problems. Super professional and friendly—highly recommend!

Evan from 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.

James from Superior HVAC Service repaired our furnace after it started making a loud humming noise. He replaced the blower motor, cleaned the compartment, and tested it twice. The system runs smooth and quiet now under our Superior Membership
