There is a chance the condenser drain isn't allowing enough condensation to drain. Basically, there is a drain that can get plugged. Chances are, you have seen water draining from vehicles when the A/C is running. If that is restricted or blocked, it could cause what you hear.
If you look at the attachments below, they explain how to remove and replace the condenser water drain. Try this and see if there is a lot of water that comes out when removed.
Let me know what you find.
