you need to take the covers off and find the evaporater coil inside and spray some coil cleaner on it the rinse very thoroughly with a garden hose with lite pressure if not youll bend the fins and inhibit your air flow

What is the best kind of cleaner to use to clean the condenser coils outside of your house and where can I buy it?

And..... after you clean the coils, how do you know if you got it all cleaned? Should you take the protective grill off while doing this so a brush could be used to clean the "fins" a little better?
