I wanted to let you know that your technician, Shawn, was absolutely outstanding. He explained what he was doing and showed us how to oil the garage door (I had no idea we were supposed to do that). He obviously takes great pride in his work which reflects well on ABC.. I will definitely use ABC again. I recommend a raise!
Thank you,
