The water pressure throughout our entire home had dropped to almost nothing over the weekend. The plumber systematically checked the system, found our main water pressure reducing valve had failed internally, and replaced it to restore perfect flow.

Our AC started making a terrible rattling noise right before the summer heat hit. Mike from Superior HVAC came out the same day, found a failing fan motor, and replaced it quickly. He was super friendly, honest about the pricing, and got everything running perfectly. Awesome service!

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 had air conditioner maintenance done and noticed an immediate improvement. The technician was friendly and professional. Will call them next year when needed again!
