Called this service because our furnace wasn’t working properly. Superior HVAC Service completed a boiler tune-up and safety inspection. He cleaned the burners, checked the venting, and tested CO levels. The boiler now runs quietly and efficiently. Same day service and I will definitely use them again!

Superior HVAC service was awesome start to finish. My furnace died on the coldest night of the year and they came out late night to diagnose my unit. My new furnace was installed the next day! Highly recommend them
