We decided to look into installing an air conditioner and so we called the furnace dealer with whom we already deal, Reliance. The service manager for Sudbury, Shon Cantin, came in a timely and professional manner and recommended the product we ordered, given that our furnace was almost 20 yrs old. We concurred with his recommendations and ordered our System. The two installers, Dan and Rory were absolutely punctual, professional and efficient, and gave us all the information and follow-up to our questions that we needed. We were very satisfied in all ways.
