I highly recommend Superior HVAC, Heating and Air Conditioning's water softener repair service, which was quick and easy thanks to their technician Drew.

My boiler stopped heating properly, so I called Superior HVAC Service. Sean arrived promptly, found the issue right away, and had it fixed quickly. Before leaving, he also checked my furnace to make sure everything was running efficiently. The service was professional, seamless, and exceeded my expectations!

Sean was fantastic! He arrived right on time, quickly diagnosed the issue with our electric furnace, and had it running perfectly in no time. Not only did he fix the problem, but he also took the time to answer all our questions and even taught us proper maintenance to keep it running smoothly. Professional, knowledgeable, and friendly—highly recommend Sean for any HVAC needs!

Conner replaced our heat pump, and from start to finish, he made the process stress-free. He was on time, super polite, and even made sure to clean up after himself (which I really appreciated). Our new system works perfectly, and I’m already noticing the difference. Thanks again, Conner!

We're so pleased with Connor and the Superior team. Our 20-year-old furnace died. Connor was very transparent with our options, which were limited given the age of the furnace, the issue, and specific part required. In the end, we decided to replace the furnace. To our complete surprise, it was installed that same night. Communication throughout the experience was top notch. Highly recommend!
