R&D Heating, Cooling & Electric just came out to conduct their seasonal checkup on our heating, air conditioning, and ventilating system. We are on their annual maintenance contract agreement, so they come out automatically. The technicians are really great guys all the way around! We have had several of them since we began using their services and each has been equally as good as the next. In fact, a young fellow came out a while back and he was so helpful and knowledgeable that I sent a note over to the owner to compliment him on how good he was. I think that everyone has been knowledgeable and professional. I am not really worried about price and have never been the type to focus on that. It is more the quality of work that I am concerned about when hiring in a company. The guys are always cooperative and just nice people I highly recommend using R&D Heating, Cooling & Electric!
