Superior HVAC Service upgraded our thermostat, making it much easier to control the temperature from our phone.

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!

the air handler quit during the hottest week of July. They found a weak capacitor, replaced it, cleaned the coil, and wiped the unit down. Out Superior membership plan covered most of the visit, and we were bumped up the priority list automatically. He was quick but careful, which is rare
