"I've had a contract with Betlem for a few years and continue to be very satisfied with their service. They are very thorough. I have an annual service of my air conditioning (in the Spring) and my heat (in the Fall). They check out everything and the service takes about one hour each. I expect they will pick up on any part of the system which needs attention. Each representative has been polite, comes when expected and left me confident that I am "good to go" the rest of the year. I do not hesitate to recommend them."

R.O. - Rochester, NY


"Everyone is always helpful and courteous. The technicians are tolerant of me hanging over them to watch as they service the furnace."

C.A. - Rochester, NY
