• Compressor: The heart of the AC system, the compressor pressurizes the refrigerant, which is essential for the cooling process.
• Condenser Coil: Located outside, the condenser coil releases heat from the refrigerant, converting it from a gas to a liquid.
• Evaporator Coil: Located inside, the evaporator coil absorbs heat from the indoor air, cooling the space.
• Refrigerant: A special fluid that absorbs and releases heat, circulating throughout the system.
• Expansion Valve: Regulates the flow of refrigerant into the evaporator coil.
• Fan Motors: Used to circulate air across the condenser and evaporator coils.
• Ductwork (if applicable): The network of ducts that distributes cooled air throughout the building.
• Thermostat: Controls the AC unit, setting the desired temperature and operating mode.
