Musty Odor From Air Conditioner

We have been on the CA and OR coast for a couple of months,no need for the AC. When we moved inland and the weather warmed up,there was a "musty"odor from the unit when we turned it on. This has never happened before,so we are a little concerned about mold in the ducting or ?? We have left it on for an hour or so and the odor is still there.
Any advice or comments?

    You need to get up on the roof and clean the EVAPORATOR.

    Get an evaporator cleaner at any box store.

    You will be shocked at what you get off the evaporator coils.
