Called about a furnace failure after 5 on a Friday and they sent someone within 3 hours! While it was a simple fix, they explained everything, told me how to prevent it from happening again, and only charged me the diagnostic fee.

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!
