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.

The technician found a refrigerant leak that another company missed. Honest, knowledgeable, and fairly priced.

Overall, I had a good experience. The repair turned out to be much more complicated than anyone expected, and in the end my air conditioner needed to be replaced rather than repaired. While it was frustrating to be without A/C during an extreme heat wave, the team was responsive, kept me informed, and worked to get everything resolved. The new unit is working great, and I'm very happy with the final result. I appreciate their professionalism and would recommend them.

Superior was quick to service my broken water heater; next-day service and I had a new heater up and running. Very professional and friendly.

Called first thing in the morning when our AC wouldn't turn on at all. Turned out to be a tripped breaker from a bad capacitor. Fixed within the hour, and the house was cool again before the afternoon heat set in.

Superior HVAC Service did a thorough seasonal maintenance tune-up that brought our aging system back to peak performance. The technician chemically cleaned the heavily fouled outdoor condenser coils, checked the compressor amp draw against factory specs, and provided a comprehensive digital health report of our system.

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.
