We were having a prevailing issue that we kind of put off for a while and finally decided to do something about it. We have been working with R&D Heating and Cooling for about 14 years now so we went with them for the work. Everything always goes very smoothly with R&D, they have a professional group of technicians who are very knowledgeable in the field. They were able to complete the job very quickly and gave us a great price per usual. We will continue to recommend them to others and use them in the future if necessary.
