How to DIY and Replace 12V Mini-Split Air Conditioner

Here are the steps to replace a 12v mini-split air conditioner:

• Turn Off the Power Supply

  Cut off the mini-split system's power supply. This entails turning off the circuit breaker or unplugging the device from the electrical outlet. This step must be taken first to avoid accidents and to safeguard the installer and the system.

• Remove the Air Conditioner Unit

  Carefully remove the old AC unit. To do this, first, remove any screws or fasteners that hold the unit in place. After that, disconnect any connecting lines, such as ductwork, piping, or electrical wiring. It is crucial to take extra care when handling these components because they may be fragile or contain residual airflow or refrigerants.

• Prepare the Installation Area

  After removing the old unit, inspect the area for any necessary repairs or modifications. This may involve fixing holes left by the previous unit, cleaning the area, or making structural alterations to accommodate the new mini-split system.

• Install the Indoor Unit Mounting Bracket

  Install the indoor unit's mounting plate or bracket. Ensure it is level and securely fastened. The indoor unit will be held in place by this mounting plate.

• Install the Outdoor Unit Pad

  Place the outdoor unit on a solid, flat surface, such as a concrete slab or a pre-made mounting bracket. Ensure the outdoor unit is positioned according to local building codes and the manufacturer's recommendations regarding clearance and airflow.

• Connect the Lines

  Connect the refrigerant lines (suction and liquid lines) between the indoor and outdoor units. Ensure the connections are secure and leak-free. Additionally, connect the drainage line from the indoor unit to the outdoor unit to ensure proper condensate removal.

• Electrical Connection

  Connect the electrical wiring according to the manufacturer's instructions. This typically involves connecting the power supply, control wiring, and any additional components (e.g., a thermostat) as specified in the installation manual.

• Install the Outdoor Unit

  Place the outdoor unit on a solid, flat surface, such as a concrete slab or a pre-made mounting bracket. Ensure the outdoor unit is positioned according to local building codes and the manufacturer's recommendations regarding clearance and airflow.
