My furnace wasn’t keeping the house warm, so I reached out to Superior HVAC Service. Sean showed up on time, diagnosed the problem quickly, and had it fixed before I knew it. He also checked my water heater to ensure everything was working properly. Excellent service—highly recommend!

Had an amazing experience with Superior HVAC thanks to their technician, Drew. He showed up right on time, was super friendly, and clearly knew what he was doing. He took the time to explain the issue with my water heater in simple terms and fixed it quickly without making a mess.What really impressed me was how professional and respectful he was the entire time—no upselling, just honest, quality work. You can tell he takes pride in his job. If you’re booking with Superior, ask for Drew. You won’t be disappointed!
