Will, should I leave the air con running all day or turn it off when I go out? I get asked this one quite a bit.
For most homes, there's no need to keep cooling an empty house all day just because you're worried it'll use more electricity to cool down later.
If you're heading out for several hours, switching it off or allowing a higher temperature will generally save energy.
There are exceptions, particularly with different tariffs, solar setups and households with specific cooling needs.
But don't believe the old story that leaving your AC running constantly is always cheaper. It's not that simple.

Sometimes the smallest part can stop the whole air conditioner.

People often assume that when their AC stops working, they're up for a complete replacement. Not necessarily.

A failed capacitor, faulty sensor or electrical component can be enough to stop a system from operating properly.

Of course, you need to diagnose the actual problem before deciding whether a repair makes sense. That's something I always encourage people to do.

After 33 years in the industry, I've seen plenty of situations where understanding what's failed is far more useful than immediately talking about buying a new unit.

💡 FUN FACT: Air conditioning wasn't invented to keep us cool!

Believe it or not, we have a printing problem to thank for modern air conditioning!

Back in 1902, a young engineer named Willis Carrier was asked to solve a problem at a printing company in New York.

Humidity was causing the paper to expand and contract, making it difficult to line up the colours during printing.

His solution? A machine that controlled the temperature and humidity in the printing room.

It wasn't actually designed to keep people comfortable, but it ended up changing the way we live.

Fast forward more than 120 years, and I reckon most Queenslanders would agree that air conditioning is one invention we're pretty grateful for, especially when Brisbane summer rolls around! ☀️

Funny to think it all started with a printing problem!

Who remembers summer before air conditioning? ☀️

I reckon plenty of Brisbane locals will remember sleeping with every window open, a pedestal fan going flat out and hoping for a breeze.

We've certainly come a long way!

After 33 years working in air conditioning, I've seen just how much it's changed the way we live through a Queensland summer.

I'm curious. Did you grow up with air conditioning, or were you part of the fan-and-open-window generation?

The dog usually figures it out first 🐶
Want to know where the coolest spot in the house is?
Don’t bother with a thermometer. Watch the dog.
Pets are pretty good at finding the comfortable spots in a home, and during summer you’ll often find them stretched out on cool tiles or wherever the air is moving.
One thing worth remembering though: if you leave the AC running for pets while you’re out, they don't necessarily need the house icy cold. A sensible temperature, plenty of water and somewhere out of direct sun will usually make for a much happier afternoon.
Judging by some of the dogs I meet on jobs, they consider the air conditioner theirs anyway. 😄

Ever noticed one side of your house is harder to keep cool in the afternoon?
Your air conditioner hasn’t suddenly become lazy. A room with large west-facing windows can pick up a serious amount of heat once that afternoon sun hits the glass.
Before assuming you need a bigger AC, have a look at what the sun is doing. External shade, awnings, blinds and curtains can make a noticeable difference to how much heat the system has to deal with.
After 33 years in air conditioning, I’m a big believer in looking at the whole room, not just the machine hanging on the wall.

Sometimes I walk into homes where every bedroom door is open and the AC is trying to cool areas nobody is actually using.
If you have a ducted system with zoning, use it.
There’s not much point asking your system to cool the spare bedroom, guest room and other unused spaces just because they're there. Zoning lets you concentrate the cooling where the family actually is.
Just remember that every ducted system is designed differently, so you still need to use the zones the way your particular system was designed to operate.
If you're not really sure what all those zone buttons do, you're definitely not the only one.

You can walk into two homes with both air conditioners set at 24°C and one can feel beautifully cool while the other still feels uncomfortable.
Temperature is only part of the story.
Humidity, air movement, where the sun hits, how well the home is insulated and even where you’re sitting in relation to the airflow all affect how comfortable you feel.
It’s why I don’t think there’s one “magic” number everyone should have their AC set to.
The best setting is the one where you’re comfortable without making the system work unnecessarily hard.

Here's something people don't always think about.
Your air conditioner can be doing exactly what it's supposed to do while your house is working against it.
Sun pouring through western windows, gaps around doors, poor insulation and leaving unused rooms open can all add to the amount of heat you're asking the AC to deal with.
Before automatically reaching for the remote and dropping another couple of degrees, try the simple stuff. Close the blinds on the sunny side of the house, shut doors to rooms you're not using and stop hot air sneaking in where you can.

Sometimes the cheapest way to help your air conditioner is to give it less heat to fight in the first place.

Here’s an old statistic that surprised me.
When the ABS specifically surveyed Queensland household energy use back in 2009, 67% of Queensland households were already using at least one air conditioner for cooling. About a third used one, and another third used two or more.
Well that was more than 15 years ago. Air conditioning stopped being considered a luxury in a lot of homes a long time ago.

We sleep with it. Work with it. The kids do their homework under it. The dog usually finds the coolest spot directly underneath it. 😄
I spend my days working on air conditioners, no longer a luxury but something that's become part of everyday Queensland life.
