I have a 30x30 metal building. I have no windows. What would be the

unit but I have no windows and not sure if cutting the corregated

If the building has no insulation you would be wasting your time. Just
leave the door open.

I am in the process of insulating it. The wals are 2x4 and they have
r-13 with paper face. I am putting foam board in the garage doors.

R-30 is going in the ceiling with a 6 milieter clear plastic vapor
barrier. I just started doing that.

Arent those mini systems expensive? Money is kind of tight.

I have been looking on craigslist for used heat pumps/air conditioners
that sit outside but have not had much luck.
