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

An indoor coil is indeed a common component of both heat pumps and air conditioners. In air conditioning systems, the indoor coil functions as the evaporator coil, where the refrigerant absorbs heat from the indoor air, cooling the space. In heat pumps, this indoor coil also plays a crucial role during the heating cycle, allowing the refrigerant to release heat into the indoor environment.

Both systems rely on this component to regulate temperature effectively, making it essential for their operation. Therefore, affirming that the statement is true is accurate, as the indoor coil is integral to the function of both heat pumps and air conditioners in conditioning indoor air.
