Great company and great service. The AC replacement was done faster than expected, and the team was very respectful of my home. They explained the process clearly and made everything stress-free. My new system works perfectly and cools evenly throughout the house.

Beyond ecstatic with the work this company has provided my family in one of the coldest times of the year… Last night my furnace stopped working so I called a couple of different places and landed on superior. Their customer service was amazing and it wasn’t long until I had a technician at my door to help, after just an hour of trying to find the problem the HVAC tech I was provided (Kurtis) figured out that the wiring for the ignition had gone bad. He brought everything he needed to possibly fix the issue so he didn’t even need to go get parts. Within just a couple hours of calling, my furnace was working just as good as before. I will be recommending superior to anyone I know because I’m very impressed with the price and support throughout this whole situation.

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.
