Sydney summers can place considerable pressure on household electricity use. Air conditioners run for longer, refrigerators work harder, pool equipment may operate more frequently and children home for the holidays can mean more devices, cooking and laundry throughout the day.

That does not mean you need to sit in a dark room while quietly melting.

The most effective way to save energy this summer is to concentrate on the equipment that uses the most electricity and reduce the amount of work it needs to do. Small changes to cooling, shading, appliance use and household routines can collectively make a noticeable difference.

Some improvements cost nothing. Others require a modest investment or professional electrical work. The right combination will depend on your home, its existing electrical system and how your household uses energy.

Start With the Biggest Summer Energy User

For many Sydney households, cooling is one of the largest contributors to summer electricity use. Depending on the climate and the home, heating and cooling can account for between 20 and 50 per cent of household energy consumption.

That makes your air conditioner the logical place to begin.

You do not necessarily need to stop using it. The aim is to cool your home efficiently rather than forcing the system to work harder than necessary.

Choose a sensible temperature

Setting the thermostat extremely low will not cool the room instantly. It simply asks the system to continue operating until it reaches a lower temperature.

The Australian Government recommends setting an air conditioner between approximately 25°C and 27°C during summer. Each degree of additional cooling can increase energy use by around 5 to 10 per cent.

The ideal temperature will vary between households, but a moderate setting is usually more economical than setting the unit to its lowest possible temperature.

Cool only the rooms you are using

There is little value in cooling unused bedrooms, studies or guest rooms.

Close internal doors where appropriate and concentrate cooling on occupied areas. For ducted systems with zoning, use the available controls rather than automatically cooling the entire property.

Avoid switching an air conditioner on while doors or windows are open. The cooled air escapes, warm air enters and the unit must work continuously to compensate.

Clean the filters

Dust and debris restrict airflow through an air conditioner. That can make the unit less effective and place additional strain on the system.

Check the manufacturer’s instructions for cleaning removable filters and arrange professional servicing where required. The Australian Government recommends keeping indoor units, filters, vents and louvres clean and organising regular servicing before peak use.

A dirty or poorly maintained system may also produce unpleasant smells, increased noise or weaker airflow.

Use Ceiling Fans Before Reaching for the Air Conditioner

Ceiling fans use much less electricity than air conditioning and can be enough to keep a room comfortable on milder summer days.

Fans do not reduce the actual room temperature. Instead, moving air helps moisture evaporate from your skin, making you feel cooler. Government energy guidance estimates that a fan can reduce the perceived temperature by about 3°C and may cost only a few cents per hour to run.

On hotter days, a ceiling fan can be used alongside the air conditioner. The moving air may allow you to set the thermostat a little higher while remaining comfortable.

Remember to switch the fan off when the room is empty. Unlike an air conditioner, a fan is cooling the people rather than the space.

Older fans that wobble, hum or provide poor airflow may need maintenance or replacement. A licensed electrician can safely install new ceiling fans, wall controls or compatible remote-control systems.

Stop Heat Entering Before You Pay to Remove It

Cooling a home becomes much easier when less heat is entering in the first place.

Windows exposed to direct summer sun can transfer considerable heat into a room. West-facing windows can be particularly difficult during the late afternoon, when outside temperatures are often at their highest.

Simple measures include:

• Closing blinds or curtains before direct sunlight reaches the glass
• Using external awnings or shade where suitable
• Keeping external doors closed during the hottest part of the day
• Sealing avoidable gaps around doors and windows
• Opening the home later when the outside temperature falls
• Using cross-ventilation when conditions are cooler

Thick, closely fitted curtains can reduce heat transfer through windows. Draught-proofing can also help prevent cooled air from escaping through gaps around doors and frames.

The timing matters. Waiting until the room is already hot before closing the blinds means the air conditioner must remove heat that could have been blocked earlier.

Understand Your Electricity Tariff

It is often claimed that electricity is always cheaper at night. That is not necessarily true.

Households on a flat-rate tariff generally pay the same usage rate throughout the day. Households with a smart meter may instead be on a time-of-use plan, where electricity prices vary between peak, shoulder and off-peak periods.

Your bill or electricity retailer can tell you which arrangement applies to your property.

When a time-of-use tariff applies, moving flexible activities away from peak periods may help reduce costs. These activities might include:

• Running the dishwasher
• Washing clothes
• Charging an electric vehicle
• Operating pool equipment
• Using certain programmable appliances
• Heating water, depending on the system and tariff

The NSW Government advises that households with smart meters and time-of-use plans may be able to reduce their bills by shifting suitable energy use into cheaper periods.

Do not change your household routine based on a general assumption. Check the tariff first.

Homes with rooftop solar may have a different opportunity. Running suitable appliances during the middle of the day can allow the household to use more of the electricity it is generating rather than purchasing that energy from the grid.

Make Laundry Less Energy-Hungry

Summer provides a simple opportunity to reduce laundry-related energy use.

Whenever practical, use the clothesline rather than the dryer. Dryers are useful during wet weather or when clothing is needed urgently, but sunshine and moving air do the job without drawing electricity.

Washing in cold water can also reduce energy use because the machine does not need to heat the water. Check garment labels and select a suitable cycle rather than assuming every load requires warm or hot water.

Other practical steps include:

• Washing full loads rather than several small ones
• Selecting shorter or eco cycles where suitable
• Using the correct spin speed to remove more water before drying
• Cleaning the dryer lint filter after every load
• Avoiding overfilling the machine
• Maintaining adequate ventilation around the dryer

Lint accumulation can restrict airflow and make a dryer operate for longer. It can also create a fire risk, so filters and accessible vents should be kept clean.

Avoid drying wet clothing inside closed rooms without adequate ventilation. The additional moisture can make the home feel hotter and more humid, which may then increase the need for mechanical cooling.

Reduce Heat Created Inside the Home

On a very hot day, the appliances inside your home can add to the cooling load.

Ovens, stovetops, clothes dryers and some older lighting generate heat while operating. This does not mean they can never be used, but timing and choice can make the home more comfortable.

Consider:

• Cooking outdoors where appropriate and safe
• Using a microwave, air fryer or smaller appliance for modest meals
• Preparing food earlier in the day
• Running the dishwasher after the kitchen has cooled
• Switching off unnecessary lights
• Turning off devices that are not being used
• Avoiding the oven during the hottest part of the afternoon

Your refrigerator should remain on, of course, but it can also be used more efficiently. Make sure its door seals properly, allow warm food to cool before placing it inside and leave enough ventilation around the appliance.

Do not set the refrigerator or freezer colder than necessary. Excessively cold settings make the compressor work harder without providing a meaningful household benefit.

Switch Off Unused Appliances Properly

Many appliances continue to draw a small amount of electricity while in standby mode.

One device may make little difference, but a home containing multiple televisions, gaming consoles, computers, chargers and entertainment systems can accumulate unnecessary standby consumption.

Switch off non-essential devices at the wall when they will not be used for an extended period, particularly before leaving for a summer holiday. Timers and smart plugs can also help manage equipment that does not need to operate continuously.

Do not switch off refrigerators, freezers, medical equipment, security systems or other essential devices. Australian Government energy guidance specifically excludes these items from general switch-off advice.

You should also avoid placing smart plugs or timers on high-load equipment unless the device is specifically rated and suitable for that purpose.

Choose Efficient Appliances When Replacement Is Due

Replacing a functioning appliance purely to save energy is not always economical. However, when an air conditioner, refrigerator, washing machine or dryer has reached the end of its useful life, energy efficiency should form part of the buying decision.

In Australia, the Energy Rating Label allows consumers to compare similar appliances. More stars generally indicate greater energy efficiency, while the kilowatt-hour figure provides an estimate of annual energy consumption under standard test conditions.

Compare products of a similar type and capacity. A very large appliance may consume more electricity overall than a smaller model, even when both have strong star ratings.

For air conditioners, look for the Zoned Energy Rating Label. This provides performance information across different Australian climate zones and can help buyers select equipment suited to local conditions.

Consider the expected running cost over the life of the appliance, not just the purchase price.

Could Smart Controls Help?

Smart home technology can improve energy management when it solves a specific problem.

Useful options may include:

• Programmable air-conditioning controls
• Smart thermostats
• Timers for selected appliances
• Automated blinds
• Motion sensors for lighting
• Smart power outlets
• Energy-monitoring systems
• Apps that display household electricity use

Automation can prevent equipment from running unnecessarily, but it is not a magic solution. Poorly configured smart technology can simply automate inefficient habits.

The real benefit comes from using controls to match energy consumption with the way the household operates. For example, a timer may turn off an air conditioner after everyone is asleep, while an energy monitor may reveal that pool equipment or an older appliance is responsible for an unexpected amount of consumption.

Electrical installation work and fixed smart-home equipment should be handled by an appropriately licensed electrician.

Check Pool Pumps, Outdoor Equipment and Holiday Lighting

Swimming pools can be substantial energy users, particularly when pumps run for longer than necessary.

Check whether the operating schedule is appropriate for the pool, its equipment and the season. A pool professional can advise on water-quality requirements, while an electrician can inspect timers, electrical supplies and damaged outdoor equipment.

Outdoor summer and Christmas lighting should also be suitable for exterior use. Check for damaged cables, cracked plugs or signs of water ingress before connecting decorations.

Do not overload outdoor power points or run unsuitable extension leads through gardens, across driveways or near pools. Any electrical equipment used around water requires particular care.

When Is an Electrical Energy Assessment Worthwhile?

If your bills remain unexpectedly high after changing household habits, there may be value in looking more closely at how the home is using electricity.

A professional assessment may identify:

• Ageing or inefficient electrical equipment
• Circuits operating under excessive demand
• Poorly controlled pool or hot-water systems
• Inadequate ceiling-fan coverage
• Opportunities for LED lighting upgrades
• Faulty appliances or unusual consumption
• A need for improved home energy monitoring
• Switchboard limitations affecting future upgrades
• Smart controls that could reduce unnecessary operation

Appliances account for a significant share of household electricity use, so identifying which systems are responsible is more useful than trying to reduce everything equally.

Householders considering larger improvements may also be eligible for current NSW energy-saving programs or incentives. Eligibility, participating suppliers and available upgrades can change, so always check the latest NSW Government information before committing to work.

Practical Electrical Improvements for a Cooler Home

Some of the most effective summer improvements require appropriate electrical installation rather than a complete home renovation.

• Ceiling-fan installation
• LED lighting upgrades
• Smart-home controls and automation
• Additional power points
• Dedicated circuits for high-demand appliances
• Switchboard inspections and upgrades
• Electrical safety checks
• Energy-monitoring equipment
• Outdoor electrical installations
• Electrical preparation for efficient cooling systems

The aim is not to fill the home with gadgets. It is to ensure the electrical system safely supports the equipment you need and helps that equipment operate effectively.

Saving energy this summer comes down to a practical combination of sensible cooling, effective shading, efficient appliances and better control over when electricity is being used.

Start with the changes that cost nothing. Use fans where they are sufficient, keep direct heat out, adjust the thermostat and switch off equipment that is doing nothing useful.

When the home needs more substantial improvements, Faraday Group can provide clear advice and professional electrical work to help make it safer, more comfortable and better prepared for Sydney’s summer conditions.
