How to Maintain a Furnace-Mounted Whole-House Humidifier

In many parts of the country, excessively dry indoor air is an ongoing problem, especially in the winter when the air tends to be naturally dry. Maintaining proper humidity levels in your home through the use of a humidifier is essential for the protection of wood furniture and wood flooring. It is critical to make sure your humidifier works correctly and is properly maintained.

Increasing indoor humidity can be accomplished with portable humidifiers, or with a central furnace-mounted humidifier—a special piece of HVAC equipment fixed to the furnace that adds water vapor to the air discharged from your furnace. These humidifiers are used primarily in the winter heating season when humidity levels are low—dry winter air is what causes frequent static electricity discharge.1

Newer tightly constructed homes have much less air infiltration than older homes. As a result, humidity levels are more easily maintained in these newer homes, reducing the need for a humidifier.
