Humidity is the amount of moisture in the air relative to the maximum amount of moisture that it can contain at a particular temperature. Humidity has a negative impact on the home because it can lead to mold, mildew, dust mites, and family health problems. When there is less humidity, the home is heated and cooled more easily and more efficiently.

When humidity is high, there is more water vapor in the air. More energy is required to get through the vapor to change the temperature. Energy from an HVAC system is also being used to change the state of the water vapor, causing the unit to work extremely hard and use a lot of energy.

On the other hand, when the humidity of the air is rather low, less humidity can decrease your energy use by half and allow your home to be more energy efficient. Maintaining lower humidity in the home can also reduce the risk of mold and improve the air quality in the home.

Basements and crawlspaces are usually areas of the home where humidity levels are high. One way to proactively reduce moisture in the home is by encapsulating a crawlspace or reducing the moisture in the basement.
