I have a small 950 sq ft single floor house, with a crawl space and force air heating. I have a portable Air Conditioner that has a large Intake and Exhuast tube.
The issue is that none of the windows in the house will work with the brackets it includes. The AC recommends sliding windows to use the brackets. My windows open up out at an angle, as it's an older home.
I do not have the money to upgrade the windows yet, but I noticed in the crawl space, there are barely any ducts for heat. It appears as though it just lets the heat rise.
My question is, can I put the Exhaust tube under the floor, and the Intake on the same floor, and still run this air conditioner? Or is it an absolute requirement to keep the exhuast and intake going outside? I do notice the exhaust gets very hot after about 15 minutes of running on AC mode.
