Professional and FastWe’ve been having issues with our thermostat, so I called Superior HVAC Service. Liam arrived on time, diagnosed the problem right away, and had it fixed in under an hour. He was professional, friendly, and even took a moment to check the entire system to make sure everything was in working order. Highly recommend!

Our boiler suddenly stopped producing heat, and with freezing temperatures outside, we needed help fast. Cole from Superior HVAC Service arrived quickly, diagnosed a faulty pressure valve, and replaced it on the spot. He also flushed the system to remove any buildup that could cause future problems. He was efficient, polite, and made sure everything was working perfectly before leaving. Really grateful for the quick response and great service!
