That may work fine in Ohio but:
and the OP did not state his whereabouts. But if they are havng to run a window A/C unit this time of year to keep the room temp at 66* I think it's a fair bet that they are somewhere pretty far down south, not up in Ohio or points north.
Shaffer if your window unit produces no more heat than your refridgerator then it's a pretty small unit or you have an old ineffecient fridge. An a very small window unit may work well in Ohio. But most of units people use down south are fairly sizeable an throw off some real heat.
And while a small A/C will do to cool off a small box. I also assume that the OP is going to use what he already has and not go purchase a new one just to cool off wort. Because in that case a small used refridgerator with an added temp controller would be more effecient and a better value IMHO.
Also refrigerators are much more effecient than window A/C units.
I am merely trying to point out that if the OP can vent the room or the condenser coil air to the outside the unit will be much more effecient especially down south.
