How To Install Split Air Conditioner

Installing a split air conditioner requires careful planning and attention to detail. While the specific steps may vary depending on the manufacturer and model of the air conditioner, the following guide provides a general overview of the installation process. Please note that it is important to consult the manufacturer’s instructions and, if necessary, seek professional assistance for a safe and proper installation.

To install a split air conditioner, you will need the following materials:

  1. Split Air Conditioner Unit: This includes the indoor unit (also known as the evaporator) and the outdoor unit (known as the condenser). Make sure you have the appropriate size and capacity for your space.
  2. Mounting Brackets: These brackets are used to secure the indoor unit to the wall. They are typically provided with the air conditioner unit or can be purchased separately if needed.
  3. Interconnecting Cables: These cables connect the indoor and outdoor units. They include the refrigerant tubing, electrical wiring, and a condensate drain pipe. The length of these cables should be appropriate for the distance between the units.
  4. Power Tools: You will need basic power tools such as a drill and screws to mount the brackets and secure the units.
  5. Refrigerant: The specific type and amount of refrigerant required will depend on the air conditioner model. Ensure you have the correct refrigerant as recommended by the manufacturer.
  6. Electrical Wiring and Components: This includes electrical wires, a circuit breaker, and a dedicated electrical outlet for the air conditioner unit. Consult an electrician if you are not familiar with electrical work.
  7. Insulation Tape: This tape is used to insulate the refrigerant tubing connections to prevent energy loss and maintain efficiency.
  8. Leveling Tool: A leveling tool, such as a spirit level, will help ensure that the indoor unit is properly installed and balanced.
  9. Safety Equipment: Wear safety goggles, gloves, and appropriate clothing while installing the air conditioner to protect yourself from any potential hazards.

It is crucial to read the manufacturer’s instructions and consult a professional if you are unsure about any aspect of the installation process. Improper installation can lead to inefficient operation and potential damage to the air conditioner.

Step 1: Choose the Installation Location

Before installing the split air conditioner, select an appropriate location for both the indoor and outdoor units. The indoor unit should be installed on an interior wall, preferably at a higher level to ensure efficient air distribution. The outdoor unit should be placed in an open area with good airflow, away from direct sunlight, debris, and obstructions.

Step 2: Mount the Indoor Unit

Start by installing the mounting brackets for the indoor unit. Use a level to ensure the brackets are perfectly horizontal. Mark the positions for drilling holes, and then drill the holes using an appropriate drill bit. Insert wall plugs into the holes and secure the brackets using screws. Make sure the brackets are firmly attached to the wall.

Step 3: Install the Indoor Unit

Carefully lift the indoor unit and hang it onto the installed mounting brackets. Ensure it is level and securely attached. Connect the interconnecting cables, including the refrigerant tubing, electrical wiring, and condensate drain pipe, to the corresponding ports on the indoor unit. Use insulation tape to wrap the refrigerant tubing connections to prevent energy loss. Route the cables neatly along the wall and secure them in place using clips or cable ties.

Step 4: Position and Install the Outdoor Unit

Determine the optimal location for the outdoor unit, considering factors such as airflow, noise, and accessibility. Place the unit on a flat, stable surface, such as a concrete pad, and ensure it is level. Connect the interconnecting cables from the indoor unit to the corresponding ports on the outdoor unit. Be careful not to damage or bend the refrigerant tubing during the process.

Step 5: Electrical Connections

Consult a qualified electrician to perform the electrical connections for the air conditioner. Ensure that the power supply matches the requirements specified by the manufacturer. A dedicated circuit breaker and electrical outlet should be installed to support the air conditioner. The electrician will connect the electrical wiring from the indoor and outdoor units to the circuit breaker and outlet, following the appropriate safety standards and regulations.

Step 6: Refrigerant Charging

Refrigerant charging is a critical step that should be performed by a licensed professional. They will connect the refrigerant lines to the outdoor unit and ensure a proper seal. The system will then be evacuated to remove any air and moisture. Following that, the correct amount of refrigerant will be added to the system, as specified by the manufacturer’s guidelines. This process helps optimize the cooling performance and efficiency of the air conditioner.

Step 7: Test and Commission the System

After completing the installation, it is essential to test the air conditioner for proper functioning. Switch on the power and test the cooling and heating modes, as well as the fan speed and other features. Check for any unusual sounds, vibrations, or leaks. Monitor the temperature and airflow to verify that the system is operating as expected. If any issues arise, consult the manufacturer’s troubleshooting guide or contact a professional technician for assistance.

Step 8: User Manual and Maintenance

Familiarize yourself with the user manual provided by the manufacturer. It contains important information regarding the operation, maintenance, and troubleshooting of the air conditioner. Regularly clean or replace the air filters as instructed to maintain optimal performance and indoor air quality. Follow the recommended maintenance schedule, including professional inspections and servicing, to ensure the longevity and efficiency of the system.


In conclusion, installing a split air conditioner involves several key steps that should be followed carefully to ensure a safe and effective installation. These steps include choosing the installation location, mounting the indoor unit, installing the outdoor unit, making electrical connections, refrigerant charging, testing the system, and familiarizing yourself with the user manual for maintenance purposes.

It is important to consult the manufacturer’s instructions and, if needed, seek professional assistance to ensure a proper installation that maximizes the performance and longevity of the air conditioner.
