Excess moisture in the air is really not a problem in New Jersey in January. i can see it being a factor in Louisiana though. As stated above it really shouldn't cause any problems unless it gets through the lines as a liquid. More likely it will just collect in one or more of your high-pressure storage tanks. A few drops of air tool oil about every 2 or 3 hours of run time will prevent most of the problems you might encounter.

I personally would not use three in one oil because it tends to gum things up. But that's just me.
