If you're asking about a portable air conditioner, the kind that has two large hoses running to an adapter that one mounts in a window, the exhaust hose is supposed to be hot, or at least warm. That's heat that the air conditioner has absorbed from the room and is dumping outside the living space.

This is possible, but there's not much point to it. Instead of conditioning the air of the room you're in, you're starting to condition the air of the outside world as well, resulting in the room you're in getting warmer. If you want the room to be warmer, increase the temperature set on the air conditioner instead. Not only will this cut down the cost of your electric bill, but it is also more environmentally friendly.
It would be best if you would cover your air conditioner in severe weather.
