For the past two years, the semi-annual maintenance of our HVAC system by Superior HVAC Service has been consistently smooth. The technicians have been punctual, conducting their tasks with thoroughness and maintaining a professional attitude throughout. They have not only offered valuable suggestions and explanations but also provided clear recommendations for cost-saving measures. The trust I have in their commitment to quality service and customer satisfaction extends to the company as a whole. Without reservation, I confidently recommend Superior HVAC Service.

I hired their services and didn't regret it a day. At the end of the day, they double-checked everything and charged a fair price.

We had an issue with the furnace thermostat -it was not heating properly. So we contacted this repair service to get it fixed or replaced, if necessary, as soon as possible, since they have this emergency option. And they came quickly! The technician found that we needed to replace the thermostat, it was the only way out. Plus, the price was affordable.

I received three quotes from different companies to replace my 16-year-old air conditioner/heater. I chose Superior HVAC Service because of their price and the fact that they demonstrated the most knowledge. Instead of pushing for the most expensive air conditioner, they identified existing installation issues that others had overlooked. The installation team completed the work on time, even solving problems with outdated exhaust ducts connected to my water heater.

Matt, our installer from Superior HVAC Service, was professional, conscientious, friendly, and knowledgeable during the installation. This isn't the first time we've worked with them, and their consistent quality work and punctuality make them a preferred choice. Every employee we've interacted with has been great.
