Should you unplug your air conditioner when not in use?

Most households have the habit of not unplugging the air conditioner when not in use for a long time, and this is a mistake. The best way to handle long periods of non-use is to unplug the air conditioner or turn off the air conditioner’s power switch.

The correct way to turn off the air conditioner

Based on the operating principle of the air conditioner, many manufacturers advise users to turn off the air conditioner in the following steps:

  • Step 1: First, use the remote control to turn off the air conditioner.
  • Step 2: Then, you can disconnect the power source to completely stop the operation of the air conditioner, saving electricity, protecting the equipment, increasing durability, and ensuring safety for users.

What happens if you keep it plugged in even if you don’t use the air conditioner?

Wasting electricity

The weather in autumn and winter is usually cold, so basically we don’t use the air conditioner during this time. The machine is not in use, but if you don’t unplug it, it will still be in standby mode. If you observe carefully, you will see the indicator light on the air conditioner still on, which means the machine is consuming electricity. Although the amount of electricity consumed in standby mode is not much, if left for a long time, it will still cost you a certain amount of money.

Moreover, there are usually more than one air conditioner in a house, so it will consume more electricity.

Electrical risks

If you don’t unplug it, the air conditioner will always be powered on. If there is a thunderstorm or unstable electrical voltage in the house, the air conditioner may be damaged and even cause fire or explosion, posing a safety risk. Therefore, when not using the air conditioner, for the safety of your family, it is best to unplug it.

Shortens the lifespan of the air conditioner

Inside the air conditioner, there are many components. If you don’t unplug it, these components will always be powered on. Components that operate for a long time will get damaged, not only reducing the lifespan of the machine but also posing a significant danger.

Therefore, it is better to unplug the power or turn off the circuit breaker during this time, not only to maintain the air conditioner but also to ensure the safety of everyone in the family. Before that, you can also check, clean, and do basic maintenance for the equipment.

After a long period of rest, if you want to use the air conditioner again, you need to clean and check if there are any problems inside the equipment.

Yes, it is generally recommended to unplug your air conditioner during extended periods of non-use, including the winter months.

It also helps protect the unit from potential damage caused by power surges or voltage fluctuations that can occur during periods of non-use.

Unplugging your air conditioner for the winter can offer several advantages. Firstly, it can help you save money on your energy bills since air conditioners, even when turned off, can still consume small amounts of electricity when plugged in. Additionally, it can extend the lifespan of your unit by preventing unnecessary wear and tear, and it reduces the risk of fire hazards associated with prolonged electrical connections.

No, unplugging your air conditioner will not cause any damage or negatively impact its performance. On the contrary, it can actually help maintain the unit’s performance and longevity. When the air conditioner is unplugged, it gives the internal components a chance to rest and reset, ensuring they function optimally when you need them again. This practice is commonly recommended by manufacturers and HVAC specialists.

In addition to unplugging the unit, you should also consider cleaning or replacing the air filters to ensure efficient operation when you use it again. Cover the outdoor unit to protect it from the elements, and if you have a window air conditioner, consider removing it for the winter to prevent drafts and improve the insulation of your home.

For central air conditioning systems, you typically don’t need to worry about unplugging the entire system. However, it is a good idea to turn off the circuit breaker that supplies power to the outdoor compressor unit during the winter. This will ensure that no power is accidentally supplied to the unit during periods of extremely cold weather, which could damage the compressor.
