The Geelong Homeowner's Guide to Air Conditioning in Summer

Geelong summers can be unpredictable — mild one week, sweltering the next. Getting the most out of your air conditioning system isn’t just about staying comfortable; it’s about running your system efficiently without blowing your electricity bill. Here’s what every Geelong homeowner should know heading into summer.

Set Your Thermostat to 24–26°C

This is the sweet spot for cooling efficiency. Every degree below 24°C can increase your energy consumption meaningfully. A setting of 24–26°C keeps your home genuinely comfortable while minimising running costs. On milder Geelong days, consider whether you actually need the air conditioning on at all — open windows and ceiling fans are often enough.

Use Zoning if You Have It

If your ducted system has zoning capability, use it. There’s no need to cool rooms that aren’t being used. Closing off bedrooms during the day and only cooling the main living areas can make a noticeable difference to your quarterly electricity bill.

Close Blinds and Curtains During the Day

Your air conditioner will work harder (and cost more to run) if your home is absorbing heat through glass all day. Closing blinds and curtains on north and west-facing windows before the heat of the day — particularly important in Geelong’s typical summer wind patterns — reduces the load on your system significantly.

Clean or Replace Your Filters

A dirty filter restricts airflow and forces your system to work harder than it needs to. For most Geelong households, cleaning the indoor unit filters every four to six weeks during summer is enough to keep the system running efficiently. It takes five minutes and can make a real difference to both performance and energy use.

Book a Service Before the Heat Arrives

The worst time to discover your air conditioning has a problem is during a Geelong heatwave. An annual service — ideally in spring — catches small issues before they become expensive ones and ensures your system is running at peak efficiency when you need it most.
