We've been using the services of R&D Heating & Cooling for many, many years. Their technicians have installed heat pumps for us They've installed air conditioners for us. They've worked on our heating system. They've always been friendly and professional and we are very pleased. We've recommended them to many of our friends and will continue to use them ourselves. We're very happy with R&D Heating & Cooling! We have a very good relationship with them and are pleased to recommend their services to anyone and everyone!
