The air conditioners already do that. Here’s how:

Apart from the compressor and the expansion valve, the window air conditioner has two important heat exchangers: the condenser and the evaporator. Both, the condenser and the evaporator are made of number of turns of the copper tubing and are covered with the fins to increase their heat transfer rate. The evaporator is located inside the room while the condenser is located outside the room exposed to the external atmosphere.
In the summer season the evaporator acts as the cooling coil. The air flows over it, gets cooled and it is supplied to the room for producing the cooling effect. The heat absorbed by the air in the room is thrown to the external atmosphere via the condenser. This is the normal working of the window air conditioner.

To use the window AC as the heat pump in the winters the direction of the flow the refrigerant is changed by changing the position of the valve. Due to this the positions of the condenser and the evaporator gets reversed. The condenser becomes evaporator and the evaporator becomes condenser and the machine becomes the heat pump. In heat pump the condenser is located inside the room, while the evaporator is located outside the room.

The refrigerant inside the evaporator located outside the room, absorbs the heat from the atmosphere. This heat is liberated inside the room via the condenser. Thus the same coil that was producing the cooling effect in the summers produces heating effect in the winters.
