Green Term Defined: Dehumidifier

We live in a mixed humid climate and so often, you hear from the HVAC contractors in the area that there is a need to add humidification. If the house is tight – energy efficient, healthy, and durable, you should not have dry air and certainly should not need more humidity. In fact, living in the home produces humidity. If there is a problem, it will be high humidity. If you have dry air, your home is not energy-efficient.


A dehumidifier is a piece of equipment that reduces the level of humidity in the air. Humid air can contribute to mold and mildew issues in your home. It can also lead to condensation on pipes. As a rule of thumb, relative humidity in homes is preferably 30 to 50 percent.
