Just finished cleaning up a couple of outdoor units from a flood. Theses particular units had these heavy rubber-foam covers wrapped around the compressors. I removed them and washed them out. I assume they are there just for noise reduction? Just wondering if I should put them back on after they dry out? Seems like they would hold the heat in the compressor?

Yeah, the foam rubber shrouds were for noise reduction. Old Rheem condensing units had fiberglass-insulated sheet meat boxes installed around the comps. Really made a difference.
I've also found that thin rubber isopads installed under vibrating units could really help reduce noise transmission as well. Like when the condenser is located outside the wall of a bedroom. Customers were so thrilled when I isolated the units and then the wall wasn't rattling all night!

Not that this applies in your case, but I've found "noisey" compressors can be due to the hold down bolts still torqued down on running units. Some installers don't remove (or at least loosen them for some movement) those shipping bolts, and the compressor vibrations transfer to the base and can be noisey. They're typically only meant for shipping purposes, but some guys don't remove them at installation.
