Happy with the furnace repair service from Superior HVAC Sarnia. The technician was knowledgeable, professional, and took the time to explain what caused the problem and how to avoid it in the future. My heating system has been working perfectly since.

I had a fantastic experience with Superior HVAC Service. Our furnace stopped working in the middle of a cold snap, and they sent a technician the same day. He was professional, explained the repairs clearly, and didn't try to upsell me on parts I didn't need. Highly recommended!
