• Outdoor Unit: This unit houses the compressor, condenser coil, and fan. It’s responsible for removing heat from the indoor unit and releasing it outside.
• Refrigerant Lines: These insulated copper tubes connect the indoor and outdoor units, carrying the refrigerant that facilitates the heat transfer process.
• Electrical Wiring: This connects the indoor and outdoor units to the power supply and carries control signals.
• Remote Control: This allows you to control the system’s settings, such as temperature, fan speed, and mode.
