Space Pack may be your ideal. small insulated 3" tube with superior
humidity removal. Reilly Heating out of Melrose Park is the premier guy
installing in the best homes in River Forest and Oak Park. There are
alot of hacks out there, as you see none agree on what should be done,
thats because few know.. Oversize and you will be left humid and clammy.
I had 4 hacks bid and luckily Reily install. Don`t do anything without a
load calc and with Chgos heat get a high Seer.
