We had a wonderful experience with Superior HVAC.The office staff were wonderful to deal with,the technicians who came into our home to do the work were great.Everyone was not only friendly, but also very efficient.The work was done quickly and perfect.No issues of any kind. I will definitely use them again when needed and recommend them to anyone. In case you are wondering, they put in a new furnace and fixed a leak.Two thumbs up, definitely 5 stars.

Superior HVAC New Market repaired my furnace when it stopped heating properly. They responded quickly, arrived on time, and clearly explained what needed to be fixed. The furnace was up and running the same day, and the pricing was fair.

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.
