I scheduled water boiler maintenance with Superior HVAC, and it was excellent. The technician named Farid was thorough, professional, and explained everything clearly. I’m confident my heater will last longer now.

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!
