Heater maintenance service 1/16/2018

CJ quickly introduced himself as soon as I opened the door. Don't think techs in prior years did. Nice touch. Had a question about a reading listed on the service form. Nothing was wrong. Just a matter of never asking what numbers represented in the many years of having service. CJ politely & friendly answered & took me to the heater to show where info. was located on manufacturers plate. He represents your company well. more
