As the weather gets cooler, the demand for air conditioning in households decreases, and it may not even be needed for several days. So, many people wonder if they should unplug the air conditioner when not in use.

Should the air conditioner be unplugged when not in use?

Most households have the habit of not unplugging the air conditioner when it is not being used for a long time, and this is a mistake. The best practice when not using the air conditioner for an extended period is to unplug it or switch off the power socket.

What happens if you keep it plugged in without using the air conditioner?

Wasted energy

In the fall and winter, the weather is usually cold, so we generally do not use the air conditioner during this time. The machine is not in use, but if it is not unplugged, it will still be in standby mode. If you observe carefully, you will see that the indicator light on the air conditioner is still on, meaning that it is still consuming electricity. Although the power consumption in standby mode is not significant, leaving it like that for a long time will still cost you some money.

Moreover, a house usually has more than one air conditioner, which will consume even more electricity.

Electrical hazards

If the air conditioner is not unplugged, it will always be powered on. If there is a thunderstorm or unstable electrical voltage in the house, the air conditioner may be damaged, or worse, it could cause a fire or explosion, jeopardizing safety. Therefore, for the safety of your family, it is best to unplug the air conditioner when not in use.

Reduced lifespan of the air conditioner

Inside the air conditioner, there are many components that will be constantly powered on if it is not unplugged. These components will deteriorate over time, not only reducing the lifespan of the machine but also posing a significant hazard.

Therefore, it is best to unplug the power or turn off the circuit breaker during this period, not only to maintain the air conditioner but also to ensure the safety of everyone in the household. Prior to that, you can also perform a preliminary inspection, cleaning, and maintenance of the device.

After a long period of rest, if you wish to use the air conditioner again, it is necessary to clean and inspect if any issues have occurred inside the device.

The parts that need cleaning before use include the external filter screen, the condenser unit, and the gas inlet part inside. These are the parts that directly affect the cooling performance of the air conditioner. By doing so, the device will operate efficiently, safely, and ensure its lifespan.

If you are not using the air conditioner for a long period, unplug it. But if you are not using it for a short time, it is not necessary to unplug it.
