The team at Superior HVAC Service, Heating & Air Conditioningdid an amazing job replacing our old gas furnace. They were prompt, professional, and the installation was seamless. They kept the workspace clean and explained everything before they left. The new unit is efficient and quiet—highly recommend them!

Superior HVAC Sarnia helped fix my furnace when it suddenly stopped heating the house. They responded quickly, diagnosed the issue right away, and explained what needed to be repaired before starting. The furnace was up and running the same day, and the pricing was fair
