Open the Window With the Air Conditioner On? You're Only Half Right!

It becomes a fundamental configuration for many families to have an air conditioner during the summer season, while a common question also occurs: Is it possible to open the window during the operation of the air conditioner?

Some people find it too stuffy with the windows closed and need some fresh air; others insist that if the windows are open, the air conditioning is wasted. Actually, both of them are half right.

It is true that the escape of the cold air is not allowed.

The air conditioner function is simple: it circulates the interior air to cool or heat. Once the window is open, the exchange of interior and exterior air continues, and the cold air escapes rapidly, and finally the air conditioner operates at a high burden as a result of high power consumption but low cooling effect.

So from the energy-saving view, it needs the window closed to ensure the cooling effect.

Non-ventilation is not allowed as well.

Human breath (CO₂), furniture smell, humidity smell, etc. are accumulated together. With no ventilation, the indoor air quality will be worse and worse.

Have you ever experienced headaches, dry throat, and stuffiness after a long stay in the air-conditioned room?

It was not the problem of your air conditioner, but the lack of fresh air.

The right way is to open the window regularly

To keep a comfortable air-conditioned room with fresh air, here are the tips:

Open the windows for 10-20 minutes in the early morning and evening, then wait for the air to refresh before closing the windows and turning on the air conditioner.

Avoid opening windows during the hottest times of the day, as this will put excessive strain on the air conditioner.

If the air quality outside is poor, use a fresh air system, air purifier, or air conditioner with a ventilation function.

So, an air conditioner and an open window can coexist together, but it needs regulation and wisdom. Using the air conditioner wisely can keep a good coolness and health without the waste of energy.
