Does Air Conditioning Remove Humidity?

In the dog days of summer, air conditioning is a lifesaver. But does it remove humidity from the air? The answer is both yes and no.

Air conditioners are designed to lower the temperature of the air, but they don’t actually remove humidity. They work by circulating air over a cold coil, which causes water vapor to condense on the coil. This process removes heat from the air, which makes it feel cooler.

However, because the air is still full of water vapor, it can feel clammy.

Why isn't my AC system reducing humidity?

The short answer is yes, air conditioners do remove humidity from the air. In fact, this is one of the main functions of an AC unit. By removing moisture from the air, your AC unit makes it more comfortable for you to breathe and helps to prevent mold and mildew growth in your home.

-How Does Air Conditioning Remove Humidity

When the air conditioning is turned on, it begins to draw in warm air from the room. This warm air passes over a set of cold coils called the evaporator. As the warm air comes into contact with the cold coils, its temperature begins to drop.

At the same time, the moisture in the air starts to condense on the coils. This process continues until all of the moisture has been removed from both the coils and the air passing over them. The now-humidity-free air is then blown back into the room by a fan.

Conclusion

Most people believe that air conditioning removes humidity from the air. However, this is not entirely true. Air conditioners do not remove humidity, they only lower the temperature of the air.

This causes the air to feel less humid because cooler air can hold less water vapor than warm air.
