I noticed my energy bills were creeping up, and my furnace wasn’t heating the house as efficiently as before. Kevin from Superior HVAC Service came out and thoroughly inspected the system. He quickly identified that the heat exchanger was partially clogged, reducing airflow and performance. He cleaned it up, replaced a worn-out filter, and recalibrated the thermostat for better efficiency. He took the time to explain everything clearly and even gave me tips on maintaining the system to prevent future issues. The pricing was upfront, with no surprises, and my home feels much warmer now. Highly recommend their expertise and professionalism!

Sean came to help with our heat pump that was making a ton of noise. He was quick to identify the issue and provide me with the solutions going forward. He also made time to service the furnace which was overdue. Sean was kind, informative, and really helpful. I would definitely recommend using Superior, and going with Sean!
