"I have an older gas furnace that was due for a check up. The person performing this service found one problem that he was clear was not an emergency. I decided to have it fixed now rather than wait for it to fail later. He was on time, even calling a half hour ahead of time to let me know he was on his way. He was professional and courteous. He gave clear explanations to my questions and some long term recommendations on my system.Furnace inspection, tune-up and cleaning. Then replaced a part."
