About ten years ago R&D Heating and Cooling installed a new heating system. They have also installed a new hot water heater. More recently they have done some pipe work for us. They have always responded immediately as quick as showing up the same morning that you call them. The service technician that I have had the pleasure of dealing with is very nice and personable. His professionalism is impeccable. If I have to call them out for anything else I will be asking that they send him! I would definitely recommend this great group of people to anyone!
