not sure where to put this so I'm going here. My ac is leaking water after running in the heat for a long time. assuming the drain is blocked. I will be getting up there this week to clean things out ...
I use compressed air to blow out my roof top condenser on my AC. What ever you use be careful to not bend over all the little fins attached to the tubes.
I agree with Traver8 you probably not be able to oil the motor bearings.
