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!

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.
