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!
