In the summertime, the heat brings humidity to many homes around the US. Humidity is a result of moisture in your home, which can come from a variety of sources. During summer, however, the weather brings moisture with it and combines with moisture you create in your home passively. Moisture can lead to health problems, such as allergic reactions to mold and mildew. Mold and other fungi are fond of wet areas, making your basement the ideal place to grow. Your AC does some dehumidification, but that’s not its primary function.
Air conditioners work by pulling air out of your home via return ducts, cooling the air, and then recirculating it throughout your home. But sometimes all your home needs is dehumidification. Along much of the East Coast, including Pennsylvania, Maryland, DC, Delaware, and New Jersey, a lot of our heat is unbearable because of the humidity levels in the air. The sticky, thick 90º weather is awful, but when the humidity finds its way inside our homes, sometimes all you need is the movement of air. Ceiling fans are a common choice in homes with temperatures around the upper 70ºs. A ceiling fan can reduce the temperature you feel in the room by up to 10º in some cases. But do air conditioners dehumidify your home or just cool it?
