• Refrigerant: A special fluid that absorbs and releases heat, enabling the cooling process.
• Fan Motors: These motors circulate air across the condenser and evaporator coils, facilitating heat transfer.
• Thermostat: Controls the AC unit’s operation by sensing the room temperature and turning the compressor and fans on or off.
• Air Filters: These filters trap dust and debris, preventing them from clogging the coils and reducing air quality.
• Electronic Control Board (PCB): This board controls the various functions of the AC unit.
