My family member in Virginia had a no heat call on her 2000 keeprite furnace. We decided to call Link based their affiliation with Climatecare. the "we care people". Well, apparantly not enough. They sent a technician within the time period they said they would show. (Thus the 1 rating). After that, it all went downhill. The tech took 1.5 hours, made a call to the office, couldn't get the furnace running, and suggested it was either the circuit board or the gas valve (a total guess !) I made the drive up the next evening ( over an hour drive up and an hour drive back) and took a grand total of 5 minutes to diagnose that the pressure switch wasn't making. I cleared the bushes in front of the vent outside and the furnace fired up. I cycled it several times and found it worked great. Link called back and tried to sell a $400 board and or a $300 valve. No thanks and please refund the call out charge as your tech is incompetent. I would not recommend LINK to anybody until they send out fully trained and competent techicians.
