My boiler wasn't heating up properly, so I contacted the excellent ventilation and air conditioning service. Cole arrived quickly, diagnosed the problem, and fixed it as soon as possible. He also quickly inspected my oven to make sure everything was working smoothly. The service was professional, thorough and highly appreciated!

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!

On the coldest night of the year, our furnace broke! Excellent Superior HVAC arrived in a few hours and promptly got it fixed. Kurtis, the technician, was amiable and competent.

Of course, our heater stopped working on the coldest night of the year. I called Superior HVAC & Plumbing Services, and Conner was at our house within hours. He found the issue fast, replaced a faulty ignitor, and had the heat back on before the house got too cold. A real lifesaver!
