Central AC systems cool the air throughout the entire home, which is something you already know. But what you may not know is that an air conditioner can also help to keep humidity levels under control. This feature is built into any system that uses refrigeration to cool down a space, and it helps to keep you a lot more comfortable when humidity levels reach their highest during the summer months.
How an AC System Controls Humidity Levels
Refrigerant is the chemical blend that moves around the indoor and outdoor components of your air conditioning system over and over again. When it’s at the inside portion of your air conditioner—the evaporator coil—refrigerant absorbs heat from the air. The evaporator coil becomes very cold.
Some water vapor in the warm, humid air from your home then condenses on the outside of the cold coil. Think of it like a cold glass of lemonade on a hot day. Water droplets form on the outside, as water vapor in the air condenses on the glass. When it condenses on your evaporator coil, the air that blows back out to your home is less humid, meaning you feel a little more comfortable.
Why High Humidity Makes You Feel Warmer
There is some amount of moisture in the air in your home, which is a good thing. A lack of moisture means dry air, chapped lips, and dehydrated skin, which also makes you uncomfortable. An ideal relative humidity is somewhere between 30% and 50%.
Once humidity levels surpass 50%, you feel warmer because sweat cannot evaporate into the air as easily. And that’s your body’s natural way of cooling off. Turning on the air conditioner and setting it to an efficient temperature can help!
