Had an issue with my furnace not heating well, so I called Superior HVAC Service. Cole was the technician they sent, and he did a great job. He found the problem fast, got it fixed, and even made sure my water heater was running efficiently before he left. Super professional and friendly!

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!

Evan from Superior HVAC Service ran a combustion analysis on our gas furnace. He adjusted the air-to-fuel ratio and optimized performance. It runs better than it has in years.
