The Air conditioner outdoor unit, also called the condenser unit, is part of an air conditioning system that includes a propeller fan, condenser and circuit board. It is situated outside the house and is a companion to the indoor unit AC.
The main works of the outdoor unit are to remove humidity and heat from the room. AC is important in people's minds because of the indoor and outdoor parts. The indoor AC unit pressurizes the refrigerant gas and sends the refrigerant gas into the outdoor unit, and keeps the room cool.
