Operation of the wall unit air conditioner works efficiently as it sucks the warm air in a room into its cooling system. Warm air entering the unit is cooled as it passes through the air conditioning condenser. The system then reverts the cooled air back into the room. Hot air resulting from the operations of the motor running the wall unit air conditioner is pushed out via the vents in the unit’s back.
