how to find the best portable air conditioner for your needs

Before we get into the reviews, here are the key things you should know about portable air conditioners in order to make the best choice to suit your requirements.

Do all portable air conditioners require an exhaust hose and window kit?

Unfortunately, yes. 

Portable air conditioning units work in a similar fashion to fixed split system units, removing heat from inside and discarding it outside via an exhaust. Therefore portable air conditioning units all come with a window kit that you need to install.

Make sure that the unit you choose has a kit that will suit your windows, as well as an exhaust hose long enough for your requirements.

BTUs and kWs - what are they and how many do you need?

BTUs, or British Thermal Units, are a common method of measuring heat energy. 

By definition, one BTU is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

In air conditioning, the BTU rating tells us how many BTUs per hour the appliance can remove from the air. Household units generally come in the 9000 – 16000 BTU range.

In order to choose a product with an appropriate BTU rating for the size of your space, be sure to check the manufacturers guidelines. This calculator can also be used to give you an indication of what BTU/hour would be suitable.

You will also see the power measurement of KiloWat (kW) referenced in the name of most portable air conditioners. 

While kWs are definitely relevant in terms of power output and therefore cooling ability, BTUs are a more appropriate measurement when comparing products, as it takes into account the cooling efficiency of the unit, as well as the power output.

other options

If you’re really on a budget, there are a few other options available to you outlined below, including evaporative coolers or DIY methods.

Portable air conditioner Bunnings

Bunnings currently have three portable air conditioning units in their range. Two from Australian Manufacturer Arlec, and one from DeLonghi.

Users generally seem to have positive experiences with the products available from Bunnings, with most issues arising when people have too high expectations for smaller, less powerful units.

Portable air conditioner kmart

Kmart currently do not stock portable air conditioning units. 

They do however have a low cost evaporative cooler that comes with a range of speed settings and an oscillating fan function.

It is however important to understand the difference between these units and a portable air conditioner. For more information, see the section below.

Portable air conditioner Big-W

Big-W currently stock two portable air conditioners, from manufacturer Onix. These come at an affordable price point and range from 7000 -12000 BTU.

The 7000 unit is likely to be too low for most Australian users, while the 12000 could be an OK option for those on a budget.

Portable air conditioner vs evaporative cooler

During your research into portable AC units, you are likely to come across evaporative coolers.

While these may seem like an appealing (more affordable) alternative, it’s important to understand the difference between the two types of products.

The purpose of both is to lower the temperature within a space, however how they achieve this is quite different. 

In simple terms, a portable air conditioning unit cools the air by removing moisture from the air, while a evaporative cooler cools by adding moisture. Therefore if you live in a more humid part of the country you will likely want to opt for portable AC, while if you’re in a drier area, evaporative cooling may be suitable.

How to install a portable air conditioner

The below video provides a brief overview of how to install a portable air conditioning unit.

Be sure to read the manufacturer’s instructions carefully as installation is likely to differ between brands and models.

DIY Air conditioners

If you’re feeling creative and don’t mind a bit of DIY, there’s a few clever methods available for you to create your own low cost cooler, at a fraction of the price of the portable AC units.

Needless to say, water and electricity don’t mix, so we advise consulting an expert before employing any of these methods. Proceed at your own risk!
