True or False: An outdoor coil is a common component of heat pumps and air conditioners.

An outdoor coil is indeed a common component of both heat pumps and air conditioners. In these systems, the outdoor coil acts as a heat exchanger, facilitating the transfer of heat between the refrigerant and the outside air. In air conditioning mode, the outdoor coil expels heat absorbed from inside the building to the outside environment. Conversely, in heat pump mode, it absorbs heat from the outdoor air and transfers it inside, even in cooler conditions. This dual functionality is key to the operation of both system types, making the presence of an outdoor coil essential for their effectiveness. Heat pumps and air conditioners rely on the outdoor coil to manage thermal energy exchange, which is fundamental to their design and performance.
