This is our fourth dealing with Central Heating in the past month - hot water tank service then replacement, A/C service then replacement, and duct cleaning. In all instances we were notified by text that technicians were coming and they showed up on time, fully prepared for the job they were here for. All the technicians we dealt with, four different guys, were all very polite, courteous and very helpful. Stephanie on the service desk was also great to deal with on the phone, scheduling and ordering equipment. All our dealings with Central Heating and the employees has been five star. Would use them and recommend them in a heartbeat!
