Last week I needed an air conditioner repaired and I was lucky to bump into Superior HVAC Service. They are honest, hardworking guys. The prices were reasonable, and they were very responsible about leaving my house as clean as they found it. You will not be disappointed!

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!
