The guy in florida, two ton hasher, does great stuff on his porch, if youve got a porch to do it i'd go with that.

You need intake at the garage door, I'd get these for security reason.

Then make sure that your roof has an opening for the air to release.

This has a nice thermostat feature

Then I'd get a return vent mount it to the ceiling, connect ducting in the attic so it isn't uber loud and connect it to this
