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!

Kurtis did an absolutely amazing job with my water heater. From start to finish, he was professional, knowledgeable, and took the time to explain everything in detail. He quickly diagnosed the issue, walked me through the options, and made sure the work was done properly and safely. You can tell he takes pride in his work and genuinely cares about doing things the right way. The whole process was smooth, stress-free, and I’m extremely happy with the results. I wouldn’t hesitate to recommend Kurtis to anyone looking for reliable, honest service.

The only company that was able to solve my complicated tankless water heater problem was Superior HVAC. They are obviously very knowledgeable in their industry, and I greatly appreciate their assistance. Even the mess was cleaned up by their technician, Brian.
