Thanks for the replys. The AC would be for my mom's dog when she stays
in the summer, it's very hot and humid in the summer, so not as
ridiculous as you may think. Joe, thanks for the info on the Hot Dawg,
that's still an option, especially if low noise. I can get the 93%
Goodman for about $300 more than the Modine, so I'm going to have to
think some more. The reason I have to run such a long vent pipe is
that I have a very steep pitch roof and I can't run the pipe straight
up from the furnace location as it would be visible from the street
side of the house so there will be a bit of a horizontal run to get it
to the proper exit location. It's probably going to be 25'- 30' or so.
I'm not sure what Pat means about running it off the the house
furnace? If you are mean running a duct out to the garage, that's
against code and the furnace wouldn't handle the extra load. I'm more
concerned about the freezing condensate in the furnace. Any other
input would be appreciated.
Thanks!

Forgot to mention, in my garage/shop I have a big old 220 V used
Frigidaire window AC unit that does a fine job in the summer. BTW, the
walls are insulated and we upgraded the ceiling insulation to 6" plus.
heater vents, there is nothing wrong with angling a Metalbestos
type vent to have it come out behind a roof peak away from the line of
sight of the street. In small towns like ours, however, it didn't
bother me or the neighbors to have the discreet vent visible, and in
fact, it might even be a small status symbol, "Hey, he's got a heated
garage!", kind of like her granite counter tops only more practical.
Bottom line, the simpler HVAC solutions are far cheaper for a garage /
shop where limited occupancy allows systems to operate well below
domicile requirements.
