• Refrigerant: A special fluid that absorbs and releases heat, circulating through the system to cool the air.
• Expansion Valve/Metering Device: Controls the flow of refrigerant into the evaporator coil.
• Blower Motor: Circulates air over the evaporator coil to cool your home.
• Fan Motor: Located in the outdoor unit, the fan motor helps to dissipate heat from the condenser coil.
