Improving the reliability of energy ratings for air conditioning
The Department of Climate Change, Energy, Environment and Water is reviewing the standard that underpins seasonal energy efficiency ratings for air conditioners. Revisions to the rating system are expected to follow.
How will changes to air conditioner energy efficiency ratings affect what I can install?
HVAC technicians and electricians may need to update product knowledge as AC energy rating standards change, affecting which units they recommend and install.
Key takeaways
- The federal government is reviewing the standard behind seasonal energy efficiency ratings for air conditioners.
- Revisions to the current rating system are expected following the DCCEEW review.
- Tradies selling or installing AC units may need to stay across changes to rated performance benchmarks.

Seeing all-electric stars in the NABERS Annual Report
The NABERS 2025/26 Annual Report shows progress in energy efficiency, electrification, indoor environment, energy management innovation and embodied carbon. The report highlights all-electric buildings among the standouts.
Why it matters: Electricians, HVAC technicians and builders may see more demand for all-electric building work as NABERS ratings reward electrification. Plumbers working on gas hot water and appliances may be affected too.
Building ministers pledge NCC modernisation
State, Territory and Commonwealth ministers responsible for housing, homelessness, planning and building met in Canberra on October 16, 2026. Reform of the National Construction Code (NCC) was on the agenda. The article gives no further detail.
Why it matters: Builders and other trades working to the NCC may eventually face changed construction requirements. No specific changes are confirmed yet, so there is no immediate impact on day-to-day work.
A2EP reveals a "hidden energy transition"
The Australian Alliance for Energy Productivity (A2EP) has released a report describing a "hidden energy transition". It says industrial heat pumps are part of an accelerating trend toward electrification.
Why it matters: Electricians and HVAC contractors may see more industrial heat pump and electrification work. The article gives little detail, so the practical scale of that demand is unclear.
