there is no conection between the outside AC fan motor and an air duct, the outside AC fan is just to cool the condensing unit.

I would get a real HRV guy and bite the bullet for a few bucks and get it fixed properly. this should not be comming on and a AC unit fan is not a cheep one to run. Also you are using the aire exchange in the summer that fan will be running twice as much and I imagin replacing that fan will be a lot more expensive than getting the aire exchange hooked up properly.
