Maintenance on my tankless water heater went perfectly with Superior HVAC Heating and AirConditioning. The technician named Sean was thorough and ensured the system worked optimally. Excellent customer service and professionalism.

I contacted Superior HVAC for an emergency on Family Day.They were excellent and easy to deal with.The technician who showed up was Matthew and he was great!Very honest, clear communication, clean and concise with what I needed to do and what the next steps would be. I would defiantly use them again, and would be comfortable referring Matthew.

Called this service because our furnace wasn’t working properly. Superior HVAC Service completed a boiler tune-up and safety inspection. He cleaned the burners, checked the venting, and tested CO levels. The boiler now runs quietly and efficiently. Same day service and I will definitely use them again!

I recently had my furnace replaced by Superior HVAC Cambridge and couldn’t be happier with the experience. From the initial consultation to the final installation, the team was professional, knowledgeable, and incredibly efficient. They took the time to explain my options clearly and helped me choose the best system for my home and budget. The installation was completed on time, and they left everything spotless when they finished. My home is already noticeably warmer and more energy efficient. I highly recommend Superior HVAC Cambridge to anyone needing a reliable and stress-free furnace replacement!

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.
