How to Close Down a Whole House Humidifier During Summer Months
A whole house humidifier, or central humidifier, puts moisture into the heating system so that it comes through a home's heating vents. A whole house humidifier provides an adjustable, comfortable level of humidity during dry winter months. With the high relative humidity during summer months, it is not necessary to inject extra humidity into a home. A whole house humidifier should be cleaned and closed down for the summer. Annual maintenance will ensure smooth operation when the seasons change. Does this Spark an idea?

Locate the 4-inch metal duct connected to the central humidifier case. This connects to the air supply plenum. Inside the duct, locate a damper and damper control lever near the main plenum. Turn the damper lever to the closed or "summer" position. This blocks the flow of cold air supply into the humidifier and redirects the air to the house duct work.
