NSW Energy Saving Scheme: Can You Get a Rebate on Air Conditioning?

If you've been putting off upgrading your air conditioner because of the upfront cost, here's some good news: the NSW Government's Energy Savings Scheme (ESS) could help you save hundreds, sometimes over a thousand dollars, on the cost of installing a new, energy-efficient system.

But before you get excited about a big "rebate cheque" arriving in the mail, it's worth understanding how the scheme actually works. Let's break it all down, plain and simple.

What Is the NSW Energy Savings Scheme?

The Energy Savings Scheme (ESS) is NSW's largest energy-efficiency program, designed to help households and small businesses reduce their energy use and greenhouse gas emissions. Running until 2050, it provides financial incentives to encourage people to switch to energy-efficient appliances - including high-efficiency air conditioners.

The goal? To support NSW in cutting emissions by 70% by 2035 and reaching net zero by 2050. Upgrading your air conditioner is one of the most effective ways households can contribute to that target while saving money at the same time.

So, Is It a "Rebate" or a Discount?

This is where a lot of people get confused. The NSW air conditioning "rebate" is not a cash refund you apply for after installation. Instead, it's an upfront discount applied directly to your installation quote before you pay a cent.

Here's how it works behind the scenes:

1. You arrange the installation of an eligible, high-efficiency reverse-cycle air conditioner with an accredited installer.
2. The installer calculates the energy your new system will save over its lifetime.
3. Those projected savings are converted into Energy Savings Certificates (ESCs).
4. The value of those certificates is deducted from your total cost

No paperwork. No waiting. No chasing money. The saving is built right into your quote.

How Much Can You Save?

There's no single fixed rebate amount — the discount varies depending on several factors. However, as a general guide:

• New split system installation (e.g. 6kW): Discounts typically range from $200 to $550+
• Replacing an old air conditioner with a 6kW split system: Discounts can be around $500 to $600+
• Larger or ducted systems: Discounts can range from $500 up to $2,600+ depending on efficiency rating and system size

Important: These are indicative figures. The actual discount you receive will depend on the model's efficiency rating, your climate zone, whether you're replacing an old system, and the complexity of the installation. Always ask your installer to show the ESS discount clearly in your quote.

What Air Conditioners Are Eligible?

Not every air conditioner qualifies. To be eligible under the ESS, your new system generally needs to:

• Be a reverse-cycle air conditioner (split system or ducted)
• Meet minimum energy performance standards (MEPS) and carry a strong energy star rating
• Be installed by an accredited ESS provider: this is non-negotiable

The higher the star rating, the greater the potential energy savings, and therefore the higher your discount. If you're replacing a very old or inefficient system, you're likely to attract a larger incentive because the scheme rewards the bigger jump in energy performance.

Who Is Eligible?

The good news is that eligibility is fairly broad. The incentive is open to:

• Homeowners (owner-occupiers) across NSW
• Small business owners in NSW
• Landlords, under specific pathways. Speak to an accredited provider about your options

The key requirements are:

• The installation must occur at a NSW property
• You must use an accredited installer partnered with an Accredited Certificate Provider (ACP)
• The air conditioner installed must meet the efficiency requirements of the scheme
• You may need to provide a recent electricity bill or your property's NMI (National Metering Identifier) number

If you already have a highly energy-efficient air conditioner, you may not be eligible. The incentive is based on the potential energy savings your new appliance will deliver compared to what you currently have.

Does It Apply to Both Split Systems and Ducted Systems?

Yes. The ESS incentive applies to both:

• Split system air conditioners (single room or multi-head)
• Ducted air conditioning systems

Both types are eligible, provided they meet the efficiency requirements. In fact, if you're installing multiple units on the same property, you may be eligible for a discount on each qualifying unit.

How Do I Claim the Discount?

The process is much simpler than most people expect:

1. Contact Climacool for a quote on your new air conditioner.
2. We'll assess your property and the right system size for your needs.
3. Your quote will clearly show the ESS discount applied — no hidden steps.
4. You'll need to provide a recent electricity bill (or your NMI number if you're a new property owner).
5. Once you approve the quote and pay a deposit, our team handles the rest.

That's it. The rebate is baked in from the start.

Why Use an Accredited Installer Like Climacool?

This is the part that matters most. You can only access the ESS discount through an installer who is partnered with an Accredited Certificate Provider (ACP). Choosing a non-accredited installer means missing out on the discount entirely — full stop.

By choosing Climacool, you get:

• Guaranteed ESS eligibility assessment before you commit
• Transparent quotes with the discount clearly outlined
• Quality installation that meets the scheme's compliance requirements
• Expert advice on the right system size and model for your home or business
• No confusing paperwork, we manage the certificate process for you

Tips to Maximise Your Discount

Want to get the most out of the scheme? Keep these in mind:

• Replace an older, inefficient system rather than just adding a new one -  the greater the efficiency jump, the higher your incentive.
• Choose a higher-rated model  -  units with superior energy ratings generate more ESCs and therefore a larger discount.
• Compare quotes -  different accredited installers may offer different prices and discount levels, so it pays to shop around.
• Don't chase the headline number  -  focus on the right system size and efficiency for your home. A well-sized system will save you more over its lifetime than a cheaper, poorly matched one.
• Check current eligibility before you book - the ESS rules are reviewed and updated periodically (the ESS Rule was last updated in September 2025), so always confirm the latest requirements at the time of your quote.

The Bottom Line

Yes — you can absolutely get a rebate (well, an upfront discount) on air conditioning in NSW. The Energy Savings Scheme makes upgrading to a more efficient system more affordable than ever, and the savings don't stop there. A newer, high-efficiency reverse-cycle unit can cut your running costs significantly compared to older equipment — especially if you've been relying on inefficient electric heaters or ageing window units.

The key is working with an accredited installer who can guide you through the process, ensure your system qualifies, and make sure the discount is properly applied to your quote.
