It's over 15 years old and has been through worse times, but the tech team they send in for maintenance just resurrected it.

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.

Sean came to help with our heat pump that was making a ton of noise. He was quick to identify the issue and provide me with the solutions going forward. He also made time to service the furnace which was overdue. Sean was kind, informative, and really helpful. I would definitely recommend using Superior, and going with Sean!
