Grab some exhaust vent hose and a bilge fan. I put in a "dryer duct outlet" type self-closing vent outlet in the bottom section of my garage door, has a 4" pipe connection that I can hook a portable A/C unit to or hook up a 4" bilge fan and 4" shop exhaust tubing to to run vehicles indoors, Y'ed into 2 3" pieces.
example:

Or you can use the aluminum flex crap for dryer ducts, the thicker stuff, as it's a lot cheaper or free in my profession, but doesn't last as long and gets ruined if you step on it or look at it wrong, lol.
