Our air conditioner started leaking water around the indoor unit and we called Superior HVAC immediately. The technician unclogged the condensate drain line and cleaned the surrounding components. He explained what caused the backup and how to avoid it in the future. Everything has been working properly since then

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.

Huge shoutout to Ryan for helping us out with our heat pump. It was blowing lukewarm air during a freezing week, but he diagnosed a bad defrost board and got it swapped out in no time. Truly a lifesaver, highly recommend Superior HVAC!

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 water pressure in our upstairs shower had dropped to a miserable trickle over the last few months. The tech diagnosed a failing balancing spool inside the shower valve body, replaced the internal cartridge, and restored perfect pressure.

Had Superior come out because my furnace was making a loud banging noise when it kicked on. Turned out to be a delayed ignition issue caused by a dirty burner. The tech cleaned everything thoroughly, tested it several times to make sure it was resolved, and explained why it's a safety concern to let it go. Really appreciate the safety-first approac
