As the Aussie summer approaches, the last thing you want is to switch on your air conditioner on a scorching day only to find it struggling, or worse, not working at all. Just like your car needs a service before a long trip, your AC system needs a little TLC before peak summer hits. We want your home to stay cool, comfortable, and efficient all season long. Here’s a straightforward checklist to help you prepare your air conditioner for the summer heat.

Clean or Replace Your Filters

Why it matters:
Dirty filters restrict airflow, reduce cooling efficiency, and put extra strain on your system.

What to do:

  • Check your filters every 1–2 months.
  • Wash reusable filters gently with warm water and allow them to dry completely.
  • Replace disposable filters if they look clogged or discoloured.

Tip: A clean filter can improve your system’s efficiency by up to 15%.

Check Your Outdoor Unit

Why it matters:
The outdoor condenser needs clear airflow to work efficiently, if it’s clogged or blocked, performance drops.

What to do:

  • Clear away leaves, dirt, and debris from around the unit.
  • Trim any nearby plants or shrubs at least 30cm back.
  • Give the fins a gentle clean with a soft brush or low-pressure hose (never use high pressure).

Inspect Your Vents and Airflow

Why it matters:
Blocked or dirty vents reduce airflow and cooling performance.

What to do:

  • Make sure indoor vents are open and unblocked by furniture or curtains.
  • Wipe down vent covers with a damp cloth.
  • Check for any odd smells or weak airflow, which could indicate a bigger issue.

Test the Thermostat

Why it matters:
A poorly calibrated or broken thermostat can cause your AC to overwork or cycle incorrectly.

What to do:

  • Turn on your air con and set it to a comfortable temperature (usually 22–24°C).
  • Make sure the room cools evenly.
  • Consider upgrading to a smart thermostat for better energy efficiency and control.

Look for Unusual Noises or Smells

Why it matters:
Strange sounds or smells can signal mechanical issues, mould, or dust build-up.

What to do:

  • Listen for rattling, grinding, or whirring noises.
  • Sniff for musty or burnt odours.
  • If anything seems off, call in a licensed technician to inspect it.

Schedule a Professional AC Service

Why it matters:
Even if your system seems fine, a pre-summer service can spot hidden issues and ensure your unit runs efficiently.
