Air conditioning forms an important part of the home, especially in the warmer months. But as common sense tells us, wherever there’s a popular technology, a lot of myths and false advice usually accompany it. If not corrected, those myths can take the life out of these useful technologies. This article debunks three myths circulating about air conditioning, all leading to bad practices among users.

Myth 1: Lowering the Thermostat Cools Your Home Faster

This leads a lot of people to think that, if they want to cool their home fast, they should set the thermostat at 30 degrees below its current room temperature.

However, air conditioners cool at a constant rate. If it is set at 70 degrees, it will cool at a constant rate until 70 degrees is reached. If it is set at 30 degrees, it will cool at a constant rate until 30 degrees is reached. There is no value in setting it at a much lower temperature because it will not speed up the cooling process.

Myth 2: Air Conditioning Units Only Cool the Air

Although making air cooler is the basic air conditioning function, air conditioners play a more important role of lowering the humidity level. By lowering the humidity level, indoor air out of air conditioners becomes more comfortable, and mould can be prevented.

Myth 3: Turning Off the AC When You're Not Home Saves Energy

Why do so many people think that shutting off the air conditioner when they leave home saves energy? In a poorly insulated house, turning off the system can result in a hotter home for which the unit must work harder when it is turned on later. It can be more energy-efficient to use a programmable thermostat to maintain a consistent temperature.

Myth 4: Bigger is Always Better

The size of air conditioner isn’t the bigger the better, for example, an improper-sizing air unit could more likely to experience inefficient cycling operations, additional wear and tear, and higher power consumption.

Myth 5: Air Conditioners Don't Need Regular Maintenance

To keep your air-conditioning unit in good condition and energy efficient, it is important to maintain it regularly. If it isn't maintained, the unit will become less efficient, resulting in higher energy expenses, and it could breakdown.

Myth 6: Ceiling Fans Cool Rooms

Ceiling fans do not cool the room, they only make people feel cooler due to wind chill effect. Ceiling fans should be turned off in unoccupied rooms to save energy.

Key Learnings and Actionable Insights

  • Understand that air conditioners cool at a constant rate, regardless of temperature settings.
  • Remember that air conditioners also reduce humidity, not just temperature.
  • Use programmable thermostats to maintain an efficient and steady temperature.
  • Choose an air conditioner size appropriate for your space.
  • Prioritise regular maintenance to ensure efficiency and longevity of your unit.
  • Utilise ceiling fans for personal comfort and turn them off when not needed.
