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.

We called Superior HVAC because our air conditioner was running constantly without cooling the house properly. The technician found a refrigerant leak and repaired it the same day. He recharged the system and checked all the airflow levels afterward. The cooling works perfectly now

Superior HVAC fixed an issue with our air conditioner that was blowing warm air. The technician replaced a failed capacitor and the system was cooling properly before he left
