Is it a new or an old window unit? Assuming your looking to refill it I will assume it is an old window unit which most likely uses R-22 refrigerant.

All it is is the freon coolant has run out on the ac. You can either take it to any discount tire, firestone, or just brakes and they can refill it for about $100. Or you can get the freon from any automotive store or walmart for about $30 and do it yourself.
