The previous owner of my house had C/A installed 2 years ago but
didn't put it into the bathrooms (2 fulls and half bath).

I'm now considering adding it to the bathrooms. I called the company
that installed the system. The guy said that C/A vents in a bathroom
are not a good idea b/c
1) you'll freeze when you're wet, coming out of the shower
2) in the winter when the system is off, the moisture will rise up into
the ducts and possibly create a mold problem, unless I'm super careful
to close the vents.
3) He recommended to instead install exhaust fans to suck the moisture out
after a shower. He said it'll put some of the C/A out if the door is
open
but he still feels it's better.

Any ideas? Does this make sense?

Also, if I do install exhaust fans, do they need to vent outside? I
thought
I once read or heard that there are fans than can exhaust right into the
attic.
I have a crawlspace attic that currently houses the blower and the ducts.
I may use for storage one day but don't currently.

Simply the guy is a hack. Find a real A/C contractor.
I live in Arizona and we have vents and exhausts in the bathrooms. I have
stayed in lots of hotels in CA and there are vents in the bathrooms. I use
the exhaust during showers, not baths. Do these bathrooms have windows?
Adding vents to the bathrooms may create other problems. First is the unit
big enough to add in the extra sq ft? Is there enough air flow to add the
extra sq ft? Is the old duct work in an configuration as to add in the new
vents?

How is your home heated? Through the same duct work as the a/c? Some how if
there was that much moisture in your home you would be having more problems
than mold just in the bathrooms.

Just my opinion, take it for what you paid for it.
