Since you can only be in one room at a time, why cool all of them? A portable air conditioner lets you keep your cool wherever you go. These aren't the old-fashioned units you mount on windows. Sleek and high-tech looking, portable air conditioners have wheels and handles that help you move them from room to room with ease.
They use "eco-friendly" coolant, they automatically drain condensation, and they can operate as a dehumidifier and a fan. A compact version cranks out 8,000 BTUs of cool, enough to temper your kitchen while you cook, and then keep your master bedroom comfortable through the night.
