As the temperature rises, cool down with a brand-name air conditioner. Split-system, reverse-cycle models are quiet and effective.

How it works

Confused by the language? A split system refers to a unit comprised of two parts – one is attached to the internal wall of your home, while the other is fixed to the exterior of the house to exhaust the heat out. Reverse cycle refers to a model with both heating and cooling functions. A split-system, reverse-cycle model is able to cool/heat one or more adjoining rooms, usually covering a living room, bedroom or study.

Size it up

It’s essential to match the power of a unit to the room size. Choice tester Chris Barnes, team leader for household products, says the factors you need to take into account are, “room size, insulation and window direction, as well as window dressings, such as curtains or awnings”. Insulation is the key to keep your home cool in summer and warm in winter. “Good insulation means the air conditioner has less work to do,” says Barnes. For more advice, talk to your local supplier, or use Choice’s sizing calculator.

Modern miracle

Now faster and more efficient, high-tech inverter systems are now available for many reverse-cycle units. These systems alter the fan and motor speeds, so they maintain a constant temperature. And as a bonus, these air-conditioners increase energy efficiency and reduce running costs.

Top tips

  • Install insulation
  • Cover windows with curtains, awnings or shade trees
  • Use ceiling fans to assist the cooling and heating effect
  • Close off the rooms to be air conditioned
  • Clean the filters regularly to keep the system operating quietly and efficiently
  • Have the air conditioning system maintained regularly
