Water Heater Installation in Lebanon, PA 17046

May 16, 2023

“Steve and Landon were courteous, efficient and very professional. Our old heater was still working, and Steve checked it out to in case it could be repaired instead of replaced. However he found it was installed in 2009, which meant it was 14 years old and probably on its way out. So we replaced it. Now we have lovely hot water, which for us it is essential because we both suffer from arthritis. We’re very happy and very grateful. The best part was it cost us $1,050 less than another company we called to look at it was charging, and for longer warranty period."
