I'm looking to cool roughly ~800 sq. ft. in the summer. I looked at both 15,000 and 12,000 BTU ACs. The 15,000 is MASSIVE and would most likely need a brace as it would protrude quite a bit our of the window. I'd also likely need help installing it and storing it in the winter. It was rated for 850 sq. ft.
The 12,000 BTU model is only rated for 550 sq. ft. but is much more manageable. I could install it myself and have a much easier time moving it into a storage area in the winter.
Will the 12,000 use more energy than the 15,000 trying to cool an area that the 15,000 is rated for?
