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!
