My boiler started making strange noises, so I contacted Superior HVAC Service. Farid arrived on time, diagnosed the issue right away, and had it repaired quickly. He even checked my furnace to ensure everything else was working properly. Excellent service from a knowledgeable technician!

When my furnace started blowing cold air, I reached out to Superior HVAC Service. Ian arrived right on time, explained the issue clearly, and got straight to work. In no time, the heat was back, and he even took a moment to inspect my boiler. Definitely a company I’ll trust for future HVAC needs!

Mike from 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.
