I noticed my boiler wasn’t heating properly, so I reached out to Superior HVAC Service. Ian came by, quickly diagnosed the issue, and had it fixed in no time. He also made sure my tankless water heater was working efficiently before he left. Great service—super professional and knowledgeable!

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!
