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!
Some high-efficiency furnaces do have a condensate trap which retains water
when shut down and I would imagine that freezing could damage it. It might
be practical to install a heat tape or similarly protect it. You would
probably have to get specific information from the manufacturer.
