You can't hurt anything about the wall unless you cut out framing
lumber. There really is nothing about the installation that even
fastens to the wall unless you create something for your own
purposes. There are two copper lines involved and probably power
and control wiring. It might be neater and cleaner to install one
sleeve though the wall between studs that is well caulked and
sealed. Send the lines and conduits through the sleeve - grow
foam with a little paint or caulk on the outside to seal the
lines.

not sure if this is the right forum.

i'm planning on installing a "split" air conditioning
and heating unit in my attached 2 car garage (presently
insulated but unconditioned/unheated).

the side i'd like to mount the air handler/cooling/heating
unit on is a load bearing wall.

i might be worried over nothing, but since it is a load
bearing wall, would mounting that "split" part of the system
to the studs on that wall create any potential structural
problems. i don't see how it would, but thought i'd get
some opinions.

the other question is, in order to run the lines to that
split unit to the outside condensor/fan, we need to drill
openings in that load bearing wall. so if you go in between
the studs, it should be fine - right ? - how would a
reputable contractor seal up these holes after they've
run the lines ? (since the Tyvek, and CDX plyscore thats
under the vinyl siding is compromised by the hole)...is
it just a matter of injecting some sealing foam/compound?

thanks in advance for any responses.
