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!

Sean came to help with our heat pump that was making a ton of noise. He was quick to identify the issue and provide me with the solutions going forward. He also made time to service the furnace which was overdue. Sean was kind, informative, and really helpful. I would definitely recommend using Superior, and going with Sean!
