For obvious reasons there is salt in the air. I have not measure it. The rest of the house has a/c and it doesn't seem to have this fast corrosion issue. The fins on the aluminum condensor unit seem fine. And they are probably 10 years old

The garage is heated and I leave it at 50 F. During the winter corrosion is not a problem. The longhood is currently there and the chrome seems fine so far.

Summer arrives and ambient humidity comes and doors swell, hair gets puffy, got some mold starting at the very bottom of the brand new sheet rock in the garages, tools corrode. All the high humidity signs.

Probably a summer high humidity salt problem, winter is cold and relatively dry in comparison.

Looking for a heavy duty unit that I can plumb to a pipe. Again the garages are tight no windows and new garage doors. Considering the bubble car thing that I've seen before.
All I'm trying to do is prevent early corrosion that will lead to rust years down the road.

Thank you everyone.
