Our airflow was awful in our house. I called Superior HVAC Service and they showed up within 3 hours and performed a full duct cleaning and balanced airflow through each vent. The house feels evenly heated for the first time this winter. Ryan was also very helpful in showing us ways to reduce our duct blockage !

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!
