Getting Your AC ready for Winter

When the glorious summer months end and winter chills are upon us, it's time to ensure your air conditioner is ready to keep you cosy and comfortable. There are a few steps that you can take as a homeowner to help prepare your AC whether ducted or split system to maintain its efficiency through the chilly days and nights. 

You can take a few simple but important steps to ensure you are well and truly ready for the winter months. The owner's manual should guide you with your specific make and model, however, this is generally how to change the temperature mode and settings. We will go into a little more detail to help you prepare.

✅ Turn Off the Power:
To ensure your safety and prevent your air conditioner from turning on accidentally, turn off the power supply by either switching off the circuit breaker or the system’s power switch.


✅ Clean Air Filter:
Next, you will need to do a few checks of your system, starting with the air filter. A dirty or clogged filter can strain the system, reducing vital airflow. This simple step can improve efficiency when the warmer months roll around. If the filter looks particularly worn or filthy, it may need to be replaced.

✅ Clean the Coils:
Over time, dust and debris can build up on your condenser coils. Regular cleaning will keep them from developing mould and mildew buildup. When you keep on top of this task, your AC will help your AC when it's required to transfer to heating mode.

✅ Keep the Outdoor Unit Clear:
Make sure there’s no debris, leaves, or branches around the outdoor condenser unit, and keep overgrown plants trimmed that are close to the unit.

✅ Cover the Outdoor Unit:
Covering the outdoor unit with a breathable cover will help protect it from harsh winter elements.

✅ Check the Ductwork:
Inspect your ductwork, as leaky ducts can result in wasted energy and compromised heating and cooling performance.

✅ Schedule a Pre-Winter Service:
Have a professional HVAC technician inspect your system before the winter season. They can check refrigerant levels, clean components, and ensure everything is functioning properly.

✅Set the Thermostat to Heat Mode:
If your system is reverse cycle, has both heating and cooling capabilities (a heat pump), switch it to heating mode. The experts recommend the temperature be set on 20–22°C during the day however, this may need to be adjusted to accommodate your space.

Additional Tips to Help Keep the Heat In

  • Make sure your house is draught-proof, as the warm air from your AC can escape through small open spaces. Keeping windows covered with curtains or blinds will also help keep your space cosy and warm.
  • It's important to have adequate insulation, especially around doors and windows. This does not directly affect your AC or how to get it ready for the winter months; it will, however, improve your home's overall energy efficiency. This simple step will make your air conditioner work better in the winter.
  • It's best not to set your system too high, as it can dry out the air and unnecessarily waste energy

By implementing these practical tips, you can maximise your system’s performance and enjoy improved comfort from your air conditioner this winter. Other benefits are that you will reduce the need for unexpected repairs and extend the lifespan of your system.
