I picked up one of those portable ac units the other day. I was going to get a window ac but I got this for a steal and couldn't turn it down. My concern is that the exhaust is supposed to be vented out but I'm afraid the hot air might be picked up on one of those IR camera those helicopters got. I've learn to live with the risks of growing but at the same time I have been very inconspicuous about it and have told no one so I would hate to blow it because of this stupid exhaust vent. Am I being overly paranoid and the exhaust won't be enough to show up on the IR cameras or is there a better less obvious way to vent it?
