The Process: Postcode to Installed in NSW
1. Check your postcode with the rebate checker — your climate zone affects the certificate calculation, so the same unit earns different discounts in Sydney versus the inland zones. 2. Quick eligibility check — property type and what's there now. 3. Accredited provider quotes — fixed installed pricing with the ESS discount already applied (see the price table below). 4. Install, usually within 1–2 weeks — the discount comes off the invoice. There is no separate cashback application; you sign the scheme nomination form with your installer before the work starts and the provider handles the rest. Most NSW installs are completed in under half a day for a back-to-back split. Full walkthrough: how to apply, step by step.
How the NSW Aircon Rebate Works
What's commonly called the "NSW air conditioning rebate" runs through the Energy Savings Scheme (ESS) — the same framework behind commercial lighting upgrades across the state. When an accredited provider installs an approved high-efficiency reverse cycle air conditioner, the energy savings generate certificates, and the certificate value is passed to you as an upfront discount on your invoice. The scheme rules for air conditioning have changed more than once since 2025, so a quote that is more than a few months old may no longer reflect current discount levels. The offer often searched as the $1,000 aircon rebate is this scheme: the amount is not a fixed $1,000, it is set by the system you install and where you live, and the full walkthrough is on our $1,000 aircon rebate, how to apply page. The top of the $200 to $2,600+ range is reached only on large, high-efficiency systems in the climate zones that generate the most certificates; a single split system in Sydney sits well below it. The exact figure is shown on your quote before you commit.
- Available for both new installations and replacements — you don't need an existing unit
- Split systems and ducted reverse cycle systems both qualify if the model meets efficiency benchmarks
- Higher-efficiency models (think 5–7 star) unlock substantially bigger discounts
- Homes and small businesses are both eligible
Sydney Metro Fixed Installed Pricing — After Rebate
No mystery quotes. These are fixed, fully installed prices for high-efficiency reverse cycle split systems in Sydney metro — supply, standard back-to-back installation and the ESS discount already applied.

Standard back-to-back installation (indoor and outdoor units on opposite sides of the same wall, single storey). Long pipe runs, double-storey installs, electrical upgrades or difficult access quoted on inspection. Rinnai prices are the exact fixed prices our quote-by-text system sends for Sydney metro. Regional NSW is covered by the same scheme and the same eligibility rules; the discount amount is calculated for your climate zone and the installed price is confirmed after your postcode check. Premium-tier systems quoted on request. Prices include GST and the ESS incentive at current certificate values; not sure what size you need? Use the sizing calculator.
Who's Eligible in NSW
Most NSW households qualify. The key requirements: the property is in NSW, the new system is an approved high-efficiency model, and the installation is performed through a scheme-accredited pathway — a regular sparkie or aircon installer without accreditation can't generate the certificates, which means no discount.
- Owner-occupiers, landlords and small businesses can all participate
- Replacing old ducted gas heating or inefficient window units attracts strong incentives (see ducted rebates below)
- Your climate zone affects the calculation — the same unit earns different amounts in Sydney vs the Riverina
The NSW Energy Savings Scheme and Air Conditioning
The Energy Savings Scheme (ESS) is the NSW Government program behind the discount, regulated by IPART. Three things about it matter when you are comparing quotes:
- There is no Service NSW application. The ESS aircon discount is not something you claim through Service NSW or lodge afterwards. You sign a nomination form with the installer before the work starts, and the accredited provider handles the rest. The installer and the Accredited Certificate Provider are not always the same business; the quote should tell you which provider the job runs under.
- The discount depends on the certificates your job generates. Capacity, efficiency rating, climate zone and whether you are replacing an old system or installing new all feed into the calculation, which is why two neighbours can get different amounts for different units.
- Only accredited installations count. An installer who is not working under an Accredited Certificate Provider cannot create the certificates, so there is no discount on that job.
How the ESS compares with Victoria’s VEU and South Australia’s REPS is in the state schemes guide.
Ducted Air Conditioning Rebate in NSW
Ducted reverse cycle systems qualify under the ESS in the same way as split systems. Because the discount is calculated on capacity and efficiency, larger ducted installs are where the bigger amounts in the range occur, but the figure that counts is the certificate amount shown on your quote, which is prepared for the actual system and property.
- The system must be an approved high-efficiency ducted reverse cycle model; it must meet the ESS efficiency benchmark for its capacity
- Replacing ducted gas heating with ducted reverse cycle is covered on its own page, including what the scheme does and does not count
- Ducted quotes are prepared on inspection rather than by text: zone count, roof space, existing ductwork and switchboard capacity all change the installed price
- Where an old ducted unit is being replaced, a like-for-like changeover using existing ductwork is usually the fastest and cheapest path

Pensioners and Concession Card Holders in NSW
The ESS air conditioning discount is not means tested and does not require a concession card, so pensioners and concession card holders are eligible on the same basis as any other NSW household, with the amount set by the system and location rather than the card. What changes for concession holders is what sits alongside it: the NSW Government runs separate energy rebates on your electricity bill that stack with the ESS discount, and some retailers offer concession pricing on top.
Our seniors and concession rebates page sets out what card holders in NSW, Victoria and South Australia can combine with an air conditioning upgrade, and where a concession card does change the rebate amount (it does in South Australia under REPS, but not in NSW under the ESS).
