How to Lower Your Power Bills with Smarter Aircon Use

How to Lower Your Power Bills with Smarter Aircon Use

Your air conditioner costs more than it should because of poor aircon efficiency, not the unit itself. Most Brisbane households crank their cooling too cold, run systems during expensive peak hours, and forget basic filter maintenance.

These habits add hundreds to your energy bills each summer. What’s happening is your system works overtime to compensate for inefficient practices.

The thing is, small changes in how you operate your air conditioning can cut costs without losing comfort. You’ll learn practical temperature settings, simple maintenance tricks, and timing strategies that reduce power use.

Let’s start with the easiest fix that delivers instant savings.

Set It Right, Save Money Tonight

Most people set their thermostat way too low, thinking it’ll cool faster. That’s a myth that costs you real money.

Three temperature facts will change how you use your air conditioner:

• Aim for 24-26°C: Your system runs efficiently in this range while keeping rooms comfortable. According to CHOICE’s energy experts, every degree below 24°C increases your running costs by 5-10%. So, setting your air conditioner to 20°C instead of 24°C means you’re paying up to 40% more on cooling costs for that same level of comfort.
• The cooling myth costs you: If you set your air conditioning to 18°C, it won’t cool your home any faster than 24°C would. It’s because your unit works at the same rate no matter what temperature you choose. Lower settings just force it to run longer and consume more power unnecessarily.
• Give your body time: Start at 26°C for a few days, then drop one degree if needed. Most people adapt quickly and find 26°C perfectly fine after the adjustment period. You’ll barely notice the difference, but your wallet definitely will over the summer months.
• Pair with ceiling fans: Moving air makes 26°C feel like 23°C through the simple wind-chill effect. Plus, fans cost cents per hour to run compared to dollars for air conditioning. You stay just as comfortable while saving money on every power bill.

Temperature controls your costs, but there’s another factor most people completely overlook.

Clean Filters Equal Lower Bills

Dirty filters force your cooling systems to use 15% more energy than they should. Fascinating, right? Also, you’ll be shocked to hear that most people never clean them. This strategy explains why power bills stay high even when temperature settings seem right.

The best part is that the fix takes no more than five minutes per month. Start by opening your split system’s front panel or finding your ducted air conditioner’s return air vents. Pull out the filter and give it a good rinse under the tap, or use your vacuum to remove all that built-up dust. Let it dry completely before sliding it back in.

Believe it or not, regular maintenance during peak cooling months pays off quickly. Clean filters let air flow freely through your system, so your compressor doesn’t strain. This habit can trim $20-30 from your monthly energy bills.

What’s more, wall units typically have one or two filters you can grab from the indoor unit. Ducted systems need checking at multiple ceiling or wall vents where return air enters. Clean filters also catch dust and allergens better, which improves your indoor air quality.

Yes, filters help, but timing your cooling right delivers even bigger savings.

Run It Smart, Not Constantly

Timing your air conditioning use can change your bills dramatically. The temperature dial is important, but when you run your system also plays a huge role. Running during peak pricing hours (typically 4 pm-9 pm) costs more than off-peak times.

Here are three ways to time your cooling and save real money:

Pre-Cool Before Peak Hours

Brisbane’s peak electricity pricing typically runs from 4 pm to 9 pm on weekdays. Run your air conditioning between 2 pm and 4 pm instead, before those expensive rates kick in. You’ll stay comfortable all evening while paying less.

Your home acts like a cooler box and holds that cold air for hours. The trick is closing your windows and curtains to trap it inside and maintain the temperature even longer.

Use Timers and Smart Controls

From our experience, most people sleep comfortably at 26-27°C, so blasting cold air all night just wastes money.

We suggest you programme your system to reduce output or switch off while you’re asleep or away from home. This simple change can save 20-30% on your cooling energy costs without affecting how comfortable you feel.

Zone Control for Ducted Systems

Ducted air conditioners with zoning let you cool only the rooms you’re actively using right now. Take our advice, you can close off unused bedrooms during the day and living areas at night. This stops you from cooling empty spaces.

For example, a family of four typically saves $40-60 monthly just by cooling selectively instead of running the whole house constantly.

Of course, even perfect habits can’t fix an inefficient machine.

Know When to Upgrade

Nobody wants to spend thousands on a new air conditioning system. The upfront cost feels painful, especially when your current unit still turns on.

Here’s when replacement pays for itself:

1. Energy star ratings: Modern energy-efficient air conditioners carry ratings of 6 stars or higher on the zoned energy rating label. The difference is huge. These units use far less power than older models, which means an energy-efficient model can cut your running costs by 30-40% compared to a 10-year-old system.
2. Old systems drain wallets: Your air conditioner might be costing you extra. How? If it’s over 10 years old, needs constant repairs, or leaves some rooms hot while others freeze. Let’s be honest, new air conditioner technology has improved so much that replacement often costs less than endless repair bills plus high energy consumption combined.
3. Match systems to homes: Split systems work well for cooling individual rooms or small homes. If you need whole-home climate control with zone options, ducted air conditioners suit larger Brisbane properties better. Renters or those on tighter budgets can look at portable air conditioners and evaporative coolers as affordable alternatives. Just remember to check the energy rating label and estimated annual energy use before buying.
