Step 1: Choose The Right Equipment

Before you begin the installation process, choose the right equipment. This includes the indoor unit, the outdoor unit, and the refrigerant lines that connect them. When it comes to installing a split system air conditioner Brisbane, it’s important to consider factors such as the size of the room. A larger room may require a larger unit, while a smaller one may only require a smaller one. When choosing the outdoor unit, consider the noise level, the location, and the size of the unit. Finally, choose the right refrigerant lines that connect the indoor and outdoor units.

Step 2: Install The Indoor Unit

The indoor unit is typically mounted on a wall or ceiling using a mounting bracket. Before mounting the unit, ensure the wall or ceiling is strong enough to support the unit’s weight. Once the mounting bracket is installed, the indoor unit can be mounted on the bracket. The unit should be level and securely fastened to the bracket.

Step 3: Install The Outdoor Unit

The outdoor unit is typically installed on a concrete pad or a flat surface. Before installing the unit, ensure the location is level and has proper drainage. The unit should be placed at least two feet away from obstructions to ensure proper airflow. Once the unit is in place, it can be bolted to the pad or surface.

Step 4: Connect The Refrigerant Lines

The refrigerant lines connect the indoor and outdoor units and are typically pre-charged with refrigerant. Before connecting the lines, ensure the unit’s power is turned off. Then, connect the lines to the indoor and outdoor units using the flare fittings provided. Tighten the fittings with a torque wrench to the manufacturer’s specifications. Once the lines are connected, use a vacuum pump to remove any air and moisture from the lines.

Step 5: Install The Condensate Drain

The indoor unit produces condensation, which must be drained away from the unit. The condensate drain is typically installed on the bottom of the unit and should be connected to a drainpipe or other suitable drain. Make sure the drain is properly secured and sloped downward to ensure proper drainage.

Step 6: Connect The Electrical Wiring

Before connecting the electrical wiring, ensure the unit’s power is turned off. Then, connect the wires to the indoor and outdoor units according to the manufacturer’s instructions. Ensure the wires are properly secured and insulated to prevent electrical shorts.

Step 7: Test The System

Once all the connections are made, turn the power back on and test the system. Ensure the indoor and outdoor units are running and the air is flowing properly. Check the refrigerant lines for any leaks and the condensate drain for proper drainage. If everything is working properly, the installation is complete.


Split air conditioning system installation can be challenging, but with the right tools and some basic knowledge, it can be done by a homeowner with some technical experience.
