My furnace wasn't working properly, and the blower didn't sound good. The technician arrived on time and checked over the furnace, dealing with a water retention problem. Very happy with the service.
Furnace not working, technician came in the day after next day, put the machine back to work. Wait for about a week, technician came in the second time to replace damaged parts.
Service person was very professional and knowledgeable. Explained everything. Cleaned up afterwards. Made sure everything was working after finishing.
