Be sure to thoroughly rinse all of the acid cleaner from the evaporator and condensor coils and fins. That acid may eat thru the copper coils.
They have been working great ever since. Also, change the return air filter (located in the stairwell on my coach) as needed.

Excellent suggestions. That's a great idea to just remove the AC units for a big ole freshen-up, it looks pretty easy (relatively speaking). I think I'll wait till it cools down a little to tackle the job.
I think I'll opt for some purple stuff (Castrol Super Clean) to assist in melting the road grime off the condenser coils. I'm thinking low pressure, hot-hot water will be the ticket to success.
