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.

Mike did an excellent job fixing our frozen pipe. He responded quickly, explained exactly what was going on, and got everything repaired efficiently. His work was clean, professional, and reasonably priced. It’s clear he knows what he’s doing and takes pride in his work. I’d highly recommend Mike to anyone needing a reliable plumber—especially in an emergency.

I contacted Superior HVAC Sarnia for a furnace issue during cold weather, and their service was excellent. The technician arrived on time, identified a faulty component, and completed the repair efficiently. Everything was tested properly before they left
