Residential energy efficiency in South Australia

When an air conditioning (AC) unit switches off after reaching the temperature set on the thermostat, it is functioning as expected and is a sign that the thermostat and AC unit are working correctly. This behaviour is part of the normal operation of a thermostat-controlled cooling system and is designed to maintain the desired temperature in the room efficiently. If these troubleshooting steps do not resolve the issue, or if you’re unsure about performing them yourself, it’s recommended that you contact a qualified HVAC technician for further diagnosis and repair. Your REPS-installed AC units come with a warranty, which can be accessed from the manufacturer. They will have the expertise and tools to reps rebate sa solar battery identify the problem and recommend the necessary repairs or replacements to get your AC unit working properly again. To be eligible for REPS incentives, certain types of air conditioners must meet national Minimum Energy Performance Standards (MEPS).
Why not try the SRES to help with the purchase cost of small-scale renewable energy systems? For example, you may receive a benefit under the SRES to help with the purchase cost of solar photovoltaic (PV) panels. And  it also includes solar water heaters, wind turbines, hydro systems, and air source heat pumps. Heating systems use a lot of energy whether it’s for a residential or commercial property, and with this scheme you can choose to upgrade. Old electric systems can be replaced with a solar heating unit or a heat pump, saving you hundreds of dollars each year.

The Retailer Energy Productivity Scheme (REPS) provides incentives for connecting your battery to a Virtual Power Plant. Combine federal STCs (~$2,300 on a 6.6kW Adelaide install), the federal battery rebate (~$2,520 on 10kWh), and the REPS VPP connection incentive (up to $2,050 plus a $150 bill credit). Enter your postcode to see your exact entitlement and get matched with one vetted local installer. Gas water heater or solar gas means a water heater that has a primary or boost fuel source of natural gas (methane) or LPG. Class 1 and class 2 dwellings are as defined by the National Construction Code. Rite Price understands not everyone can afford to pay cash for everything they purchase.
If you’re replacing an air conditioner, maybe check your insulation, windows, or lighting at the same time. Small things like sealing gaps or changing to LED bulbs don’t cost much. Now, if you have an inefficient and old air conditioner, it sucks energy, spikes usage and pushes costs even higher.
If REPS sounds familiar, that’s because it replaced the older Retailer Energy Efficiency Scheme (REES). The SA REPS hot water upgrade is an energy savings activity under the Retailer Energy Productivity Scheme (REPS). These retailers incentivise customers to reduce their energy use in order to meet their EPTs, often through discounts, rebates, vouchers, etc. for approved energy saving technologies. REPS activities are available for eligible South Australian households and businesses where the same REPS activities have not been undertaken before and where inefficient appliances exist. Please submit the online application form and a member of our team will get back to you with info about your eligibility. If you were  planning an upgrade, our team is here to help you understand what other energy-saving options are still available.

Join our installer network to access rebates, fast payments and support. We work closely with Australia’s largest Energy Retailers to deliver environmental services to homes and businesses in South Australia. In 2026, the overall target has reduced and priority group requirements have increased. This means activity delivery is more limited and focused on meeting those targets. As a result, MAC Trade Services does not currently offer appliance rebates for this activity in 2026. The appliance rebate is delivered under the Retailer Energy Productivity Scheme (REPS), which requires energy retailers to meet targets set by the South Australian Department for Energy and Mining.
This price varies depending on what hot water system is installed and if your connected to mains gas or not. The 180L heat pump units are good for smaller one bathroom units which don’t require as much hot water demand. Adhering to these maintenance practices can significantly enhance the lifespan of your air conditioner, sidestep unexpected repair costs, and maintain a consistent and comfortable indoor temperature. Regular maintenance helps maintain unit performance, conserve energy, and support environmental sustainability. Lastly, it is wise to discuss the maintenance schedule with your installer at the time of fitting.

All South Australian households and businesses can take part in the REPS. Your participation in the scheme is voluntary. Tank proved to be very well insulated because when we had a long blackout we had hot showers for three full days and warm the fourth day. Extremely happy with the hot water installation and very happy with the work carried out by Adrian and Matt; excellent job from both. If you haven’t swapped your old halogen downlights for LEDs yet, you are essentially burning money every time you flick a switch. Halogen bulbs are incredibly inefficient, converting 90% of their energy into heat rather than light. In Southern Adelaide,  the conversation around energy bills is almost always dominated by solar panels.

Always ask for a detailed quote that clearly shows any REPS discount being applied. Together with our representatives, MAC Trade Services and Ecovantage, we’re helping businesses and households improve energy efficiency with the help of energy efficient products. You could save money on upgrade costs, and reduce the size of electricity bills. Under the REPS, most energy retailers in South Australia are required to provide incentives for SA  households and businesses to achieve energy savings, and potentially lower their energy bills. Energy retailers that exceed certain thresholds are set annual targets for the delivery of energy efficiency activities to households and/or businesses. Many obliged retailers use the services of third party contractors of the scheme such as YESS.
It doesn’t matter that you are located in Adelaide, regional South Australia, or within the bush. You simply go through a certified installer, and the rebate shows up in your quote. South Australians are already facing some of the highest power bills in the country, with quarterly averages sitting around AUD 540-AUD 550. When temperatures increase to 40°C, it becomes necessary to switch on the air conditioner.
