Superior HVAC Services helped us replace our old water heater, and we couldn’t be happier. Conner was incredibly professional, arriving on time and taking care of everything efficiently. He explained the entire replacement process in detail, and the new water heater is working great!

If the hot water heater's pilot light goes out, Leo explained how to re-start it. This is a great company.
