We recently upgraded to a heat pump installation in Ontario and chose Superior HVAC. They answered all our questions and handled the install professionally. The system is quiet and efficient. Very satisfied.

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.
