Air conditioning offers a welcome respite, but with energy bills a growing concern, using it efficiently is key. Here's how to maximise your AC's effectiveness and keep your wallet happy.

Embrace the power of planning

Night-time is cooling time: In the hours of darkness, open windows and let the fresh air circulate throughout the house. This pre-cools your home naturally, giving your AC a head start when you need it most during the day.

Schedule your cool down: Invest in a programmable thermostat. Set it to turn on the AC just before you return home from work, ensuring a cool haven upon arrival, without needing to leave the unit running all day while you’re out.

Optimise your space for cool comfort

Declutter for airflow: A cluttered room traps heat. Create space around vents, and ensure nothing restricts airflow around the AC unit itself. A clear path for cool air circulation is essential. Put items you’re not using into self-storage – here are some examples of seasonal items that you could store all summer long.

Check your windows to stay cooler

Blinds are your best friend: During the hottest parts of the day, keep blinds or curtains drawn, especially on south-facing windows. This significantly reduces heat gain from direct sunlight. Consider investing in blackout or reflective blinds for maximum heat deflection.

Seal the deal: Check windows and doors for drafts. Even small gaps can allow hot air to sneak in, forcing your AC to work harder. A little weather stripping goes a long way in maintaining cool air within.

The Government has some other advice on changes you can make to your home to stay cooler.

Get the most out of your AC unit

Right-size your AC: An AC unit too large for the space cools the room rapidly, then cycles off frequently, wasting energy. Conversely, a unit too small struggles to maintain a comfortable temperature. Consult a professional to ensure your AC is properly sized for your home.

Cleanliness is key: A dirty air filter restricts airflow and reduces efficiency. Regularly clean or replace the filter according to the manufacturer's instructions.

Service with a smile: Regular maintenance by a qualified professional ensures your AC runs smoothly and efficiently. Schedule annual check-ups to identify potential issues before they become expensive problems.

Cool alternatives to consider

If you still need to reduce your air con use, here are some alternatives.

Harness the power of the fan: Ceiling fans and strategically placed standing fans circulate cool air, creating a windchill effect that enhances the feeling of coolness. They use significantly less energy than an AC unit.

Embrace the natural world: Plant trees or climbing vines around your home. They provide shade and contribute to natural cooling through evapotranspiration, the process by which plants release water vapour into the air.

A cool and refreshing shower: A shower can lower your body temperature and leave you feeling less hot and sticky.

Remember: Even small changes can make a big difference. By implementing these tips, you can ensure your AC unit operates efficiently, keeps you cool during those hot spells, helping you save money on your energy bills. So, declutter your space, embrace the night-time cool, and enjoy a comfortable summer!
