Cooling is the one appliance decision where the order matters. The kind of machine narrows it, the size of the room settles the capacity, and only then does the brand make any difference. Buying a split system a kilowatt too small is the mistake that cannot be fixed later.
The figures here come from the energy rating labels, the published noise ratings and the retailer listings each machine links to.
Start with the type
- Portable air conditioner vs split system: a 2.6kW portable needs no installer; a 3.5kW split costs more up front and cools better for less.
- Tower fan vs pedestal fan vs air circulator: a tower is slim and quiet, a pedestal moves more air for less money, a circulator stirs a whole room.
- The best evaporative coolers: where they work in Australia, and the alternative for humid cities.
Then the size
- What size split system do I need: 2.5kW for a bedroom, 3.5kW for a small living room, 5kW for open plan, 7.1kW for a whole floor.
Split systems
- Daikin vs Mitsubishi vs Fujitsu: Fujitsu sits on a retail shelf; Daikin and Mitsubishi come through installers.
- Panasonic vs Fujitsu: same price, same cooling stars, same room. Panasonic adds air purification and more heating, Fujitsu is much quieter indoors.
- The best split system air conditioners: Hisense's 2.5kW carries 6.5 cooling stars and Samsung's runs at 38 decibels.
Portable units
- The best portable air conditioners: the quiet De'Longhi owners rate best, and honest advice about the noise.
Fans
- The best tower fans: De'Longhi's dual outlets aim separately, Dyson's has no blades to clean.
- The best pedestal fans: the most air moved per dollar.
- The best ceiling fans: a DC motor, a 132cm span and a reversible winter mode are the three things that change the result.
- The best desk fans: from a foldable USB unit to the Vornado desk circulator.
- Vornado 660 vs 633: the 660 is the larger circulator; the 633DC runs on a DC motor with 99 speeds and weighs a kilo less.
Two things worth knowing before you shop
Read the climate zone on the energy label, not the headline stars. Air conditioners carry separate ratings for hot, average and cold zones under the government scheme. The same Fujitsu 2.5kW unit rates 5.5 stars for cooling in a hot zone and 5 in an average one, and heating ratings are consistently lower than cooling ratings across the whole shelf.
Oversizing an air conditioner is its own problem. A unit much larger than the room cools fast, switches off before it has removed any humidity, and starts again minutes later. The room ends up cold and clammy and the compressor wears through short cycles.
