We had a musty smell coming from our vents every time the AC ran. Technician found mold growth in the ductwork from a drainage issue, fixed the drainage, and cleaned the ducts. Smell is completely gone.

Excellent job done by Ryan recently. Not only did we receive exactly the service we intended to get, but he was by far the most productive and professional employee I’ve seen in this field of work. Keep the business rolling guys!

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!
We will deliver Residential NTI Boiler to any of these cities
