Advantage Airtech Climatecare

We had the motor replaced on my 13 yr old Carrier furnace in June 2010 after it had seized when being cleaned by another company. The motor on the furnace had not worked properly since a few weeks after it was installed only working on the 'Auto' setting of the thermostat when it was set in the 'ON' position. We have an Electronic Air Cleaner installed in the ductwork which to function properly the furnace fan needs to be running all the time ie: in the 'ON' position. I had the company that installed the motor in to check it and they told me the problem was a dirty filter. I changed the filter and there was no change in the function of the motor. I decided to change companies and called Advantage Airtech instead because they are a Carrier Dealer as I wanted the furnace checked out including the motor. The serviceman could not find anything wrong with the fan motor or any of the other furnace components as the furnace was functioning perfectly while they were here with the fan motor running when the burner wasn't lit. He told me that the problem was probably a failing circuit board which would cost approx $500. He recommended that we not bother replacing the circuit board because of the cost,and also the house was heating according to the setting on the Thermostat and the fan motor was functioning to keep the house warm. The serviceman was very pleasant and did an excellent job checking the function of the furnace components and so I agreed with the serviceman that at this time the circuit board shouldn't be changed. I was very pleased with this company.
