George came from superior hvac in an hour of me calling them to diagnose my water heater.Found issue quick game me solution.I had a new water heater installed same day.Thank you superior hvac and George
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鈥攏o upselling, just honest, quality work. You can tell he takes pride in his job. If you鈥檙e booking with Superior, ask for Drew. You won鈥檛 be disappointed!

Our water heater started leaking Friday afternoon heading into the Thanksgiving long weekend. We had been on borrowed time with it, and wanted to switch to tankless when it gave out. I called Superior around 3pm, and they had someone to the house within a few hours to have a look. They were able to book an installation Saturday morning, and Chandler had a new tankless unit installed and running by noon. He explained all the features and safety items to us, and told us to call right away if there were any issues. Overall, a great experience - thank you!
