I noticed my energy bills were creeping up, and my furnace wasn鈥檛 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!

When my water heater stopped working, I called Superior HVAC Service. Kevin arrived on time, quickly found the issue, and had it fixed before I knew it. He even checked my furnace to make sure everything was running efficiently. The service was fast, reliable, and stress-free!
