Professional and FastWe’ve been having issues with our thermostat, so I called Superior HVAC Service. Liam arrived on time, diagnosed the problem right away, and had it fixed in under an hour. He was professional, friendly, and even took a moment to check the entire system to make sure everything was in working order. Highly recommend!

Ryan from Superior HVAC Service diagnosed a bad ignition module on our furnace. He replaced it quickly and stayed until the flame sensor tested perfect. The whole experience was easy and professional.

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!
