I have a 5 year old unit and am on my 4th blower motor. 2 summers ago I had them come out to repair the blower motor on a 3 year old Carrier unit. The tech took forever to fix and even had to call out another tech, they didn't finish until after 10pm and even then the repairs weren't complete because they had to order a defrost board. The part was supposed to be replaced with manufacture warranty parts. A year later the blower motor failed again, this time I called another company, The other company tells me that they didn't use a manufactured replacement part and that the part they did put it was to big. So called efficiency to come fix the motor, luckily it was still under their 1 year warranty. 1 year and 2 months later the blower has failed again but this time all they offered was 15% off repairs.
