A step-by-step guide to split air conditioning installation

Understanding the split air conditioning installation process can help set expectations and make things smoother for everyone involved.

In this blog, we look at the process of installing a split system air conditioner with Ozcon Air Solutions.

Whether you want a new cooling solution or are curious to learn more, this overview walks you through every stage.

Preparation for split air conditioning installation

Preparation is the key to a successful split system installation.

Before installation day, it's essential to make sure your home is ready. This includes choosing the best location for your wall-mounted unit and ensuring the space is clear.

Additionally, it’s wise to consider the electrical setup required for your split system. 

Additionally, our electrical team will assess your setup to make sure everything is in place. We’ll handle considerations including:

  • Whether there is an accessible power source close to the desired location of the outdoor unit
  • Any necessary upgrades to your switchboard or wiring are at an extra cost

Step 1: Installing the indoor unit

A split system air conditioner consists of two main units: an indoor unit and an outdoor unit. The indoor unit is responsible for circulating cool or warm air within your home. The outdoor unit expels heat absorbed from inside. Together, they work seamlessly to ensure efficient temperature control.

The first step is to install the indoor unit. Our installation team will mount the unit on the interior wall, using secure brackets to keep it stable. Now, we also assess considerations such as the weight-bearing capacity of the wall and proximity to electrical connections.

Step 2: Setting up the outdoor unit

The outdoor unit plays a vital role in ensuring the overall efficiency of your split system air conditioner. It works by releasing the heat absorbed from inside your home, which makes proper placement key for optimal performance.

Choosing a spot with adequate airflow and avoiding areas with restricted space will help the unit function efficiently. Additionally, keeping the unit out of direct sunlight can help improve its longevity and maintain consistent performance. This is particularly important during the hotter months!

It’s essential to place the outdoor unit on a stable, level surface, such as a concrete slab or sturdy mounting brackets. This prevents vibrations that could lead to operational noise and potential wear and tear.

Proper installation here also means leaving enough clearance around the unit to allow for easy servicing and maintenance.

Step 3: Connecting the indoor and outdoor units

Once both units are in place, our AC installers will connect them using refrigerant piping and electrical wiring. This connection is essential for heat exchange and system communication. The refrigerant lines are carefully measured and cut to ensure minimal refrigerant loss and optimal system performance.

Proper insulation of these lines is essential to prevent energy loss and condensation, which could lead to inefficiencies or damage over time.

Electrical wiring

The electrical wiring between the units allows them to communicate effectively. This ensures that when you adjust the settings on your indoor unit, the outdoor unit responds accordingly.

Secure all connections

We’ll also ensure all connections are tightly secured and appropriately sealed. Any loose or poorly fitted connections can result in leaks. This can impact the air conditioner's ability to cool or heat effectively.

Once connected, we conduct a pressure test to verify the integrity of the refrigerant lines. This ensures there are no leaks and that the system will operate safely and efficiently.

Step 4: Electrical and refrigerant connections

Our technician will also ensure that the electrical connections are properly grounded. This is critical for safety and to prevent electrical faults.

Grounding the system correctly not only enhances operational safety but also contributes to extending the lifespan of the air conditioning unit by protecting it against power surges or electrical issues.

Additionally, we carefully calibrate refrigerant levels to ensure the system functions efficiently. Improper refrigerant levels can lead to decreased cooling performance, increased energy consumption, or even damage to the compressor.

Our team uses precise tools to measure and adjust the refrigerant. We ensure the system operates within recommended guidelines for optimal performance.

Step 5: Testing and commissioning

Once all connections are complete, we test the system for leaks and operational efficiency. This ensures everything works as intended and that there are no refrigerant leaks, which can affect performance. The technician will also ensure the air conditioner cools or heats as expected.

Is split system AC right for my home?

Split system air conditioning is a versatile and efficient solution for many homes, offering both heating and cooling capabilities. If you have specific areas you want to target or need a flexible and cost-effective system, a split system might be ideal.

For homes considering AC solutions in multiple rooms, our guide on multi-head split system air conditioners explains how these units can cover more areas effectively.
