• Compressor: The heart of the AC system, the compressor pumps refrigerant throughout the system, compressing it to create the cooling effect. It’s often the loudest component.
• Condenser Coil: Located in the outdoor unit, the condenser coil releases heat from the refrigerant.
• Evaporator Coil: Located inside the indoor unit (usually in the air handler), the evaporator coil absorbs heat from the air, cooling it.
• Fan Motors: Both the indoor and outdoor units have fan motors. The outdoor fan motor helps cool the condenser coil, while the indoor fan motor circulates cooled air throughout your home.
• Refrigerant Lines: These lines carry the refrigerant between the compressor, condenser coil, and evaporator coil.
• Ductwork: The network of ducts distributes cooled air throughout your home.
