Air Conditioning Installation

With another scorching Aussie summer on the horizon, getting a new air conditioner installed is at the top of the to-do list for many households. You've picked out the perfect unit to turn your home into a cool oasis, but now comes the most critical part: the air conditioning installation.

A proper, professional installation is the difference between a reliable, efficient system that lasts for years and a complete lemon that costs you a fortune. So, what's involved, and why is it a job you absolutely must leave to the pros?

Why You Can't DIY Your Air Con Installation in Australia

Let's get this out of the way first. In Australia, it is illegal and extremely dangerous to install your own split system or ducted air conditioner. This isn't just a recommendation; it's the law.

An air conditioning installation involves two distinct, licensed trades:

  1. Refrigeration and Air Conditioning: The system contains high-pressure refrigerant gases. Only a licensed air conditioning technician with a Refrigerant Handling Licence from the Australian Refrigeration Council (ARC) is legally allowed to handle these gases and work on the system.
  2. Electrical Work: An air conditioner is a high-power appliance that needs to be safely connected to your home's switchboard. This work can only be performed by a licensed electrician.

Attempting this yourself can lead to hefty fines, void your home insurance, and pose a serious risk of property damage or personal injury.

The Air Conditioning Installation Process: A Quick Rundown

While the specifics vary between a simple split system and a massive ducted setup, a professional installation will generally follow these key steps.

1. Site Assessment and Placement

The first thing your professional installer will do is help you choose the best spot. For a split system, this means finding a location for the indoor unit that allows for optimal airflow, and a stable, well-ventilated spot for the outdoor unit. For a ducted system, this involves a thorough inspection of your roof space to plan the ductwork runs.

2. Mounting the Units

The installer will securely mount the indoor unit to an internal wall and place the outdoor unit on a solid foundation, like a concrete slab or sturdy wall brackets, ensuring it's level and has plenty of space for airflow.

3. Running the Pipes and Cables

A hole is drilled through the wall to connect the two units. The installer then runs the copper piping (for the refrigerant), the electrical wiring, and a drainage pipe through this opening.

4. The Electrical Connection

This is a critical safety step. The licensed electrician will run a dedicated power circuit from your switchboard to the air conditioner. They will install the correct circuit breaker to protect the system and a weatherproof isolator switch near the outdoor unit, ensuring all wiring meets strict Australian safety standards.

5. Commissioning and Testing

Once everything is connected, the technician will vacuum the refrigerant lines to remove any air and moisture before charging the system with the correct amount of refrigerant. They'll then power up the system, test all functions, and make sure it's running at peak efficiency. You beauty!

A Professional Job Needs Professional Gear

A high-quality air conditioning installation is about more than just the unit itself. It's about ensuring every part of the system, especially the electrical components, is up to the task.

This is why professional installers and licensed electricians only use trade-quality gear from trusted suppliers.
