We had persistent humidity and mold issues in our bathrooms and the team assessed the whole ventilation system. They upgraded the exhaust fans and tied them into proper exterior venting. the moisture problem is completely gone

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!

Superior HVAC Sarnia helped fix my furnace when it suddenly stopped heating the house. They responded quickly, diagnosed the issue right away, and explained what needed to be repaired before starting. The furnace was up and running the same day, and the pricing was fair
