Our 4 year old furnace stopped working on Christmas Day about 5:00. Called the company that installed it but no technicians were on call. Couldn’t find anyone until I called Tradesman. Mark sent a technician (Jun) within an hour. He was not able to get the part he needed but gave us several heaters that kept us comfortable for 3 days while we waited for the parts store to open after the holidays. However, Margaret kept us informed during those days as to what was happening. Matt, another technician came out and spent the morning fixing and getting parts for the furnace which is working just fine now. Even though it took 3 days to get the parts, we always felt we were looked after. Thanks, Mark, Jun, Matt and Margaret.
