Cool change: how to plan for your perfect Aircon
February 3, 2026-4 min read
The best time to plan for new air conditioning? Before those steamy days (and muggy nights) arrive and you’re at risk of making a rushed decision in the heat of the moment. Whether you’re looking to install a split system or window wall system in a new home, a do-it-all reverse cycle system for year-round comfort, or you’re hot under the collar to upgrade to a feature-stacked smart model, it pays to research which type of air conditioner you need. And where it should go!
“Picking the wrong spot for your aircon means it will have to work harder to keep you cool, which can lead to higher running costs,” warns Scott Bazley, The Good Guys Buyer – Seasonal.
With so many options to choose from, we’ve put together this handy guide to help make finding the most cost-efficient cooling solution for your home a breeze!
Signs your Aircon needs replacing
How can you tell if your aircon is approaching retirement? Don’t sweat - there are some clear warning signs that it’s probably time for a cool change.
“If your aircon needs frequent repairs, makes strange noises or leaks excess moisture, it could be time to invest in a new cooling system,” says Scott Bazley. “Keep your eye out also for a sudden spike in your electricity bills, which may mean your air conditioner is working overtime to keep you cool.”
Consider the age of your current system, too. An older model that’s been regularly serviced should last about 10 years, while newer, more energy-efficient models generally run for about 20 years.

What type of Air Conditioning do you need?
Your perfect cooling system will depend on your budget and the size of your home. Choosing an aircon that’s too powerful for your space will burn unnecessary energy; while a model that’s too small won’t adequately cool your quarters.
Let’s run through your options so you can pick the best cooling agent for the job!
Window Wall
Got a compact space to cool? A window wall appliance is your best bet. These models don’t require a separate outdoor unit and are installed in – you guessed it! – a window or a wall.
With a smaller cooling engine under the bonnet, window wall appliances make a great budget-friendly choice. Look out for models with dust filtration (ideal for allergy sufferers), fresh-air return (for added ventilation) and energy-efficient inverter technology to curb those power bills.

Split System
If you’d like a silent achiever that’s quick and easy to install, a split system air conditioner is a top pick. Comprising an indoor unit and an outdoor unit, which can be placed anywhere within 30 metres of your home, these appliances are well suited to larger living spaces.
“The fiercest split system air conditioning units pack around 10kW of cooling power – enough to effectively chill large, open-plan spaces like your living room,” says Scott Bazley. “Many modern split system aircon units also offer value-added features like advanced filtration tech for healthier air, power cooling modes, and ionic deodorisation technology to absorb unwanted odours.”

Reverse Cycle
Want aircon that’s useful every season? A reverse cycle air conditioner will cool and heat your home. Plus, impressive energy efficiency means you can save on cooling costs. Some great futuristic features are up for grabs in today’s reverse cycle models. Think Wi-Fi connectivity for cooling your home remotely before you leave work, voice control, self-cleaning functionality and air purification for a healthier home.

Where to install your Aircon
As a general rule, air con units in your bedroom should be placed to the left or right of the bed, so you don’t have air blowing directly on you while you sleep. In other rooms, split system units should be placed in a central spot for balanced airflow.
