How to Reduce Aircon Bill in 5 Easy Ways

We’re a few weeks into spring now and while spring hasn’t really sprung yet, it’s not far off. If you were caught out by your bills for cooling your home last summer, you might be looking for some helpful “how to reduce aircon bill” tips that can make a huge difference this time around.

Though you might find yourself using your air conditioner more as you stay indoors to hide from the outdoor temperature, it is possible to do so in a way that helps you save money on your energy bills.

Here are five simple and straightforward ways that will help to save you money as you try and maintain the ideal temperature indoors this summer.

1. Set Smart Temperatures and Controls

The easiest “how to reduce aircon bill” starting point is arguably with the air conditioner controls. How you set your air con will largely dictate power consumption in your house this summer.

You’re always better off setting your air for efficiency, rather than extremes. The Australian Government’s Energy website recommends setting your air conditioner thermostat to between 25 and 27°C for cooling in most climate zones. Aim for between 18 and 20°C for heating in winter. It’s worth noting that every degree higher that you set your air conditioner can save you 5-10% in cooling costs.

We also recommend using timers and schedules to keep the aircon on only when people are at home or on their way home. These habits cut electricity usage, trim running costs and keep a comfortable indoor environment on hot days. They also protect your system from daily strain.

Most homes across Australia have more than just their air conditioners to keep the house cool. From ceiling fans to opening windows, these tools enhance the cooling effect of your aircon to the point that you won’t need to rely on your AC so much.

On a hot day spent watching TV in the living room or working from your bedroom, certainly put the aircon on. But instead of setting it to an ice-cold temperature, put it up a little higher and put the ceiling fan on too.

It will enhance the cooling effect of the air conditioner by circulating cooled air throughout the room. All while saving energy (and money) by not relying so much on your air conditioner.

Open up the windows of your home during early mornings or late evenings when the outside temperature drops. Cross-ventilation allows warm air to escape and fresh air to enter, making your indoor environment more comfortable. Good airflow helps you maintain comfort indoors without constantly adjusting the temperature and driving up your electricity bill.

You might have the most efficient air conditioning system installed in the best position of the house for maximum effect. However, that won’t help much if your household energy plan isn’t right.

Compare electricity plans regularly to make sure you’re on a competitive tariff. The Australian Government’s Energy Made Easy website makes it easy for homeowners in SA, Queensland, Tasmania, NSW and ACT. In Victoria, head to Victorian Energy Compare.

Look for plans with lower peak rates or ones that reward solar feed-in if you have solar panels installed. Some providers offer real-time smart meter data tracking to help you monitor your energy use. Adjust your energy use habits to match off-peak times.

A better energy plan can reduce electricity costs, lower your power bill and help you maximise the benefits of energy-efficient appliances, including your home air conditioning.

Try these simple passive cooling techniques and tips to save energy and reduce the need for artificial cooling:

• Close blinds and curtains during the hottest parts of the day.
• Install external shading, such as awnings or adding shade sails.
• Use draft stoppers to prevent hot air from entering through doors.
• Seal gaps in windows and walls to stop heat transfer.
• Install your air con in the best position for airflow and efficiency.

These quick “how to reduce aircon bill” wins go a long way towards improving energy efficiency and keeping your home cool. Passive cooling reduces your energy bills and helps you stay comfortable without overworking your system.

If your existing air conditioning unit has reached the end of its natural life and it’s time to shop around for a replacement, choose models that display the Zoned Energy Rating Label (ZERL).

The ZERL system shows how a unit performs in your specific Australian climate zone (also includes New Zealand and the Pacific Islands). There are three zones:

• Hot: Brisbane, Darwin and Pacific Islands
• Average: Adelaide, Perth and Sydney
• Cold: Canberra, Hobart, Melbourne and New Zealand

Reverse cycle air conditioners offer heating and cooling in one system and tend to be more energy efficient than separate units. Consider pairing your cooling system with solar panels to offset electricity costs. Ducted systems are best for large homes, while split systems sufficiently suit smaller spaces.

Look for an energy-efficient choice rated for your room size or whole home to save you money and reduce your overall electricity usage year-round.

To keep your air conditioner running efficiently, always book regular servicing with an ARC-licensed technician. Dusty filters, blocked drains or low refrigerant can increase power consumption and reduce cooling performance.

In Australia, we’re required by law to have a suitably licensed professional manage any electrical work or refrigerant handling tasks. Regular maintenance helps your system run smoothly and reduces the risk of expensive breakdowns. If your air conditioning unit is older, a technician can provide you with expert advice on whether you’re financially better off repairing the system or replacing it outright.

Just as you’ll find with hot water systems and gas heaters, air conditioner servicing helps improve energy efficiency and saves you money on your energy bills over time.

Slash Your Aircon Costs, Not Your Comfort

When it comes to how to reduce aircon bill costs, small changes really do make a huge difference.

From simple habit changes like adjusting your thermostat to sealing window gaps and using energy-efficient appliances, each step adds up. Stay on top of your aircon maintenance obligations, especially before hot summer days arrive, and know when to defer to a licensed technician.

Switch to the best available energy plan and take advantage of off-peak rates or solar credits where possible. Whether you own a ducted system or a single reverse cycle unit, these practical tips will help you save money, reduce energy consumption, and keep your house cool all summer long.
