Humidity Control

Humidity is the amount of water vapor in the air. Low humidity indicates dry air, too much of which dries out the skin, makes you feel cold or chilled even at relatively high room temperatures, and causes wood to shrink. Shrinking wood causes furniture joints to loosen, cracks between crown molding and the drywall, and cracks between boards in wood floors.

To add humidity during the winter, a device called a humidifier is installed in your home’s central heating and air conditioning system. A whole-house automatic humidifier introduces humidity into the home in the form of water vapor.
