Called Superior HVAC Services as I was having issues with hot water in my house. They sent a technician named Ian the same day. He did a thorough inspection, checked all of the fixtures in my house. Turned out my water heater was working and the mixing valve failed. He explained what caused it and how to prevent it in the future. Very knowledgeable staff and helpful. Gave a quote for services needed. I am satisfied with the service and with the technician. I hope all services are like this! Happy client here!

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.

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!
