Portable Air Conditioners

Explore this page


Portable, single duct space conditioners and spot coolers are not currently labelled or subject to Minimum Energy Performance Standards (MEPS).

There are two basic types of portable air conditioners:

  • Single duct portable space conditioners are unitary systems lying wholly within a conditioned space. They draw air from the conditioned space which then flows over the condenser and is exhausted via a single duct to the outside.
  • Spot coolers are also unitary systems lying wholly within a conditioned space, but they have no duct or air interconnection to the outside. These are generally limited to specific commercial or industrial applications and are rarely used in the residential sector.

Note: double duct portable air conditioners, with a second duct to draw air from outdoors, are covered by existing unitary air conditioner MEPS.

Portable space conditioners are not subject to energy labelling and MEPS partly because there has been no international test method for the determination of efficiency. However, recent increases in the market share of these products has prompted government to consider policy measures for these products with respect to energy efficiency.

Regulatory requirements for portable air conditioners

There are currently no regulatory requirements for these products.

What are we working on?

Portable air conditioners are being considered for regulatory options under the recently published combined air conditioner and chillers consultation RIS. The public submission period for the RIS closed on Friday 18 March 2016. A selection of the submissions are available to download.
