Anyone with an AC window unit? Energy Cost?

Fortunately I'm an ATOT millionaire, so I can afford to run my set-up for hours on end. Or until I get hungry.

The newer AC are supposedly more efficient. I'd also recommend buying a slightly smaller model...they consume less and will more then likely cool just as well.

Can I borrow the grape one please?

I always wondered how a fan would do with a block of ice behind it. I think there's some older commercial buildings in NYC that use dry ice in the basement and have shafts that go up to various floors for cooling

Lol when I first moved into my house and had no form of A/C we got a huge heat wave that I was not ready for at all so I ended up using a fan to blow over ice. It sorta helped, but not really, because it just made more humidity. Basically I just went to the store to buy ice and put it in a bucket with fan blowing in it. I didn't want to use the freezer because generating that ice would end up making more heat than the ice would cool.

I bought a 12000btu honewell portable unit for our bedroom. the bedroom is the furthest away from the furnace and with one register in the bedroom it gets toasty during the day. wife works nights so keeping the bedroom cool during the day was a top priority. I was concerned like the OP about how much it would jack up my power bill. Last month it was 5 bucks more and i should be getting next bill soon and it hit 105 a few days go. we keep it running 24/7 and the thing keeps the bedroom a awesome 62 degrees, perfect for sleeping.

This is far from rocket science. Even so, they have these yellow stickers to help EVERYONE figure out what the costs are with average use. Take your power bill and divide the amount you PAY by the usage (kWh) to find out your actual cost per kWh.
