Household Air Conditioners – Registration and Certification Requirements

There has been a change to the regulatory requirements of air conditioning units in Queensland. These units are “in-scope” equipment and primarily designed for use in residential homes.

1. At 29 January 2017, air conditioning units that incorporate flammable refrigerants were classified as risk Level 3 under the Electrical Equipment Safety System (EESS).

2. Responsible suppliers of this equipment must now be registered on the EESS database and register the equipment using a Certificate of Conformity.

Additionally, the units are required to be marked with the Regulatory Compliance Mark (RCM).

Note: these changes only apply to units manufactured/imported into Australia after 29 January 2017. Those units manufactured or imported prior to this date, that comply with the relevant standard, and have already been sold by a registered responsible supplier to a third party to on-sell, may continue to be on-sold until the supply is exhausted.

3. Air conditioners that use non-flammable or low flammable refrigerants are currently Level 1. They will become Level 2 on 1 June 2018.

Powerboard Safety ….. incorrect use can lead to house and office fires.

Power board safety

Problems with power boards can arise from:

  • Overloading the power board.
  • Dust build up in unused points.
  • Power leads becoming dislodged over time, particularly under a desk.
  • Poor placement of power cables and extension chords leading to the power board.
  • Inadequate ventilation of the power board preventing dissipation of heat generation.
  • Heavy plug-in transformers that can “over balance” and partially unplug can result in over-heating from poor connections.


  • Only using power boards with built in safety switches or circuit breakers.
  • Do not overload the power board.
  • Regularly check that all plugs are firmly fixed in power boards.
  • Ensure adequate ventilation is provided for power boards.
  • Regularly inspect power boards and leads for signs of damage and degradation.
