Ian from Superior HVAC services was highly professional and courteous. He arrived on time, efficiently repaired our water heater, and even took the extra step to inspect our furnace to ensure everything was working properly.

After speaking to several companies this weekend, I reached out to Superior when my furnace gave out. Ian was there within a couple of hours, answered all my questions and explained everything patiently and thoroughly. I called them at 130 in the afternoon and had the new furnace installed and running by 8 pm. I would definitely recommend Superior to anyone who needs assistance quickly. Very satisfied.
