Maintenance on my tankless water heater went perfectly with Superior HVAC Heating and AirConditioning. The technician named Sean was thorough and ensured the system worked optimally. Excellent customer service and professionalism.

I had Superior HVAC Service, Heating & Air Conditioningreplace my furnace last week and couldn't be happier. The quote was fair, and they didn't try to upsell me on anything I didn't need. The technicians were skilled and had the job done in just a few hours. My house has never felt warmer!

I had no clue what was wrong but they came in and were super easy to book, very cheap in comparison to other companies but I’d say they’re worth three times the amount I paid. I cannot recommend them enough. If you want good quality work. Ask them

We had uneven heating in the house and lots of dust buildup. Superior HVAC Gatineau did a full duct cleaning and also discovered a partially blocked vent causing poor airflow upstairs. After cleaning and fixing the issue, the difference is night and day. The air feels cleaner and every room heats evenly now. Really happy with the results!
