If you live in South Australia, upgrading to a new air conditioner or replacing an old unit could be more affordable than you think. Thanks to the state’s Retailer Energy Productivity Scheme (REPS), households and small businesses may be eligible for discounts that reduce upfront costs. This guide explains how the program works, what you can save, and what eligibility criteria apply.
What is the Retailer Energy Productivity Scheme (REPS)
The Retailer Energy Productivity Scheme (REPS) is South Australia’s current energy efficiency program. It encourages larger energy retailers to help households and businesses save energy by offering incentives and discounts on approved activities. One of the most common activities under REPS is the installation of high-efficiency reverse cycle air conditioners, which can replace old, inefficient heating and cooling systems.
When you upgrade through an accredited provider under REPS, you may receive a discount on the upfront cost of your new unit. The retailer earns “energy productivity credits” for helping you reduce energy demand, and passes some of that value back to you in the form of lower prices.

What Rebate Can You Get for Air Conditioners in South Australia
Typical savings range from a few hundred dollars for a small split system to well over $1,000 for a large ducted reverse cycle system.
The size of the rebate or discount depends on several factors:
- Capacity of the system (kW) – larger systems generally earn more credits
- Type of upgrade – replacing an old electric or gas heater creates more savings than adding a new unit
- Efficiency of the new model – higher star ratings and better performance mean higher energy savings and bigger incentives
- Accredited provider pricing – discounts are applied by the provider, so different companies may offer slightly different amounts
Actual amounts are not fixed — they depend on the value of certificates at the time and how your retailer/provider structures the discount.
Common Scenarios: Air Con Rebates in South Australia
The table below gives examples of common installation scenarios and the kind of rebate you might expect through the REPS program. These figures are indicative only and will vary depending on the efficiency of the unit chosen, the provider, and the certificate value at the time of installation.
| Scenario | System Size | Typical Rebate (Approx.) | Notes |
| Small bedroom or study | 2.5 kW split system | $250 – $400 | Best for single rooms; rebate depends on efficiency rating |
| Medium living area | 6 kW split system | $500 – $800 | Common size for family living spaces; higher star ratings earn bigger savings |
| Whole-home cooling | 10 kW ducted system | $1,000 – $1,400 | Rebates scale with system capacity; ducted systems earn larger incentives |
Eligibility criteria for South Australia’s Air Conditioner Rebate
To be eligible for an air conditioner discount under REPS you must:
- Be located in South Australia
- Upgrade through an accredited provider who is registered to deliver REPS activities
- Choose a product that meets efficiency standards (usually reverse cycle systems with high star ratings)

There is no income test for REPS. However, some providers may target offers to concession card holders or low-income households where the energy savings are greatest.
