LG 14,000 BTU 115V Portable Air Conditioner with 12,000 BTU Supplemental Heating

I bought it as a temporary backup: we use AC 10 out of 12 months.

Portable air conditioners are VERY inefficient. Whatever money you save from the deal will be gone in several months of using this instead of a proper air conditioner. Portable air conditioners suck cold air out in order to cool down the room. Even window air conditioners are much better than these.
