My boiler stopped heating properly, so I called Superior HVAC Service. Sean arrived promptly, found the issue right away, and had it fixed quickly. Before leaving, he also checked my furnace to make sure everything was running efficiently. The service was professional, seamless, and exceeded my expectations!

We called Superior HVAC Service for a second opinion after another company tried to sell us a completely new furnace. Robert thoroughly inspected our system and determined that only a minor repair was needed. He saved us thousands of dollars! We trust them completely.

Ryan did an excellent job of inspecting my furnace...and he also reviewed a problem he had covered in my heat exchanger. Once the heat exchanger is replaced, they will do so promptly.
