Weirdest Air Conditioning Myths We’ve Heard – Busted! Sunshine Coast

Weirdest Air Conditioning Myths We’ve Heard – Busted!

When it comes to air conditioning, there’s no shortage of myths floating around. Some of them seem logical at first, but many can actually lead to higher energy bills, reduced efficiency, or even damage to your system. Today, we’re busting some of the strangest air conditioning myths we’ve heard!

Myth 1: Cranking the Temperature Down Cools Your Home Faster
Many people believe that setting their aircon to 16°C will cool their home faster than setting it to 22°C. In reality, air conditioners work at a constant rate, cooling the air at the same speed regardless of the temperature setting. The only thing setting it lower does is make your unit work longer, which can waste energy and increase wear and tear.

Myth 2: Ceiling Fans Make Your Room Cooler
While ceiling fans can make you feel cooler by moving air over your skin, they don’t actually lower the room temperature. If no one is in the room, leaving the fan on just wastes electricity. Instead, use fans in combination with air conditioning to improve airflow and comfort.

Myth 3: Air Conditioners Only Cool the Air
Air conditioning does more than just cool your home – it also removes humidity, which is crucial in Queensland’s climate. High humidity makes the air feel much warmer than it actually is, so reducing moisture levels helps you feel more comfortable at higher temperatures.

Myth 4: You Don’t Need to Service Your Air Conditioner If It’s Running Fine
This is a dangerous myth! Even if your aircon seems to be working well, dust, mould, and debris can build up over time, reducing efficiency and air quality. Regular servicing ensures your system runs efficiently, lasts longer, and doesn’t surprise you with unexpected breakdowns.

Myth 5: Bigger Air Conditioners Are Always Better
An oversized air conditioner can actually be worse for efficiency and comfort. A unit that’s too large for your space will cool the room too quickly, leading to short cycling (turning on and off frequently), which wastes energy and doesn’t effectively remove humidity. It’s always best to have a properly sized unit for your space.

Myth 6: Closing Vents in Unused Rooms Saves Energy
If you have a ducted system, closing off vents in unused rooms might seem like a good way to save energy, but it can actually create pressure imbalances, making your system work harder. Instead, if you have zone control, use it to direct cooling efficiently without overloading the unit.

Myth 7: Using Dry Mode in Queensland Is a Good Idea
Many believe that using dry mode in Queensland is the best way to remove humidity, but it’s not always the best choice. Dry mode reduces moisture but doesn’t provide continuous cooling, which can make the space feel stuffy. In high humidity areas like Queensland, using the standard cooling mode at a moderate temperature is often the most effective way to stay comfortable.

Myth 8: Ducted Aircon Is More Expensive to Run Than Split Systems
This one depends on how you use your system! A well-zoned and properly maintained ducted system can be just as efficient as a split system when cooling multiple rooms. However, if you only need to cool one area, a split system may be the better choice.
