Scored this bad boy at the docks. Loaner free of charge till I don't need it. Now when we get a spot cleaned out we can run a fridge an window unit and anything else that may still work.
Ours is a Coleman 6250 and it was pretty efficient.
However we found that if we ran it for an hour, the fridge kept the freezy packs frozen for almost 3 hours, so we started doing that 1 on, 2-3 off, unless we really needed that window unit AC on.
The window unit was in a central room and we also had a fan that we could put outside that door to blow cool air into other parts of the house if we were working somewhere else. Not nearly as good as being in the room, but better than nothing.
