I am thinking about installing a 22,000 BTU Window A/C unit in my metal building it has sprayed foam insulation on the walls and ceiling which helped some but still very miserable during the summer.
The size of the shop is 24x30 with a 12’ high open ceiling, do you think a 22000 BTU window unit will bring the temperature down to maybe 80 – 85 degrees when it’s in the high 90’s outside?
