I have a Coleman Split AC system. It was installed in our Mobile Home in 1980. The indoor Air Handler is: Coleman Presidential 2, Model #3120B750 and Serial # is 128064431. My question is that I have a serious vibration in the house when the unit is running. From what I've been told so far is most probably the Blower Fan in the Air Handler is out of balance or bearings. I'm looking to replace the Fan and possibly the motor but can't match the parts. Can u help with this?
