Not only did the technician repair my water heater in no time, but he also knew his job and taught me how to use the system correctly. I’m happy with my choice and will recommend this company to all my friends!

I am very glad that I chose this company to repair my air conditioner! The technician was on time, polite, worked diligently and cleaned up completely when he was done. It's scary to choose from companies you've never worked with, but Superior HVAC Service was the right choice!
