I have a dual system with two 2 ton ac units, with gas furnaces. Recently the electric motor failed on the coil circulation fan. I have searched and searched, but can not find a replacement fan motor.The Comfortmaker dealers and authorized parts suppliers won't sell me the part. The dealers want to sign me up for a service call and the parts centers refer me to the dealers. Where can I buy Comfortmaker replacement parts, without being gouged by the dealers???
