A house that is heated will typically cause the air inside the house to become dry, or arid which can be uncomfortable and cause dry itchy skin, static electricity, and more.

addition, this can cause wood and other materials including that found in furniture and mouldings to shrink. Gaps and cracks can also open up in both the ceiling and walls in the house structure. Humidifier units can be employed to prevent or slow down this process and can be installed directly on the duct system.
