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!

My regular plumber was not available and i needed a hot water heater on a Saturday. Michael came at 1:30, looked it over, did some test and decided a new heater was the was to go. They arrived at. 9:30 pm with a new unit and finished the install but 11:30 pm. My guests had hot showers the next morning! Very happy with their service.

Woke up to no hot water and immediately called Superior HVAC Service. Hunter arrived on time, quickly diagnosed the issue with my tankless water heater, and had it working again in no time. He even did a quick check on my furnace to make sure everything was running smoothly. I really appreciated his professionalism and attention to detail!
