A central humidifier can be a very worthwhile investment, helping to improve the quality of the air in your home during the winter season. Once the weather begins to warm up, though, it is essential to turn off the humidifier in your home until the heating season starts up again in the fall.

In this article, we’ll take a closer look at what central humidifiers are, why it is important to turn them off after the heating season, and the steps you need to take to turn off your humidifier.

What is a Central Humidifier?

A humidifier is a piece of equipment that is designed to add moisture into the air in the form of water vapor. Humidifiers come in several different types, most of which are portable and designed to humidify a single room or area. A central humidifier, though, is connected into the home’s HVAC system, meaning that it is able to add moisture into the air throughout the entire home.

In the winter, increasing the moisture in the air can be very beneficial. Dry winter air has a tendency to dry out your skin, leading to chapped lips, nose and throat irritation, and dry, itchy skin. By increasing the moisture content in the air, though, a central humidifier is able to eliminate the potential for these issues.

Why You Need to Turn Your Central Humidifier off After Heating Season

Turning your central humidifier off after heating season is a task that is easy to forget. If don’t remember to turn off your central humidifier, though, you may end impeding your air conditioning unit’s ability to properly cool your home. Air conditioning units are designed to both cool and dehumidify the air that they pull in since the air tends to be much more humid in the summer. If your central humidifier is trying to add moisture into the air at the same time that your air conditioning unit is trying to remove it, though, your air conditioning unit will not be able to function properly.

How to Turn off a Central Humidifier

Turning off a central humidifier isn’t quite as easy as flipping a switch. However, it is a relatively simple process if you follow the right procedure. To turn off your central humidifier, use the following steps:

Step #1

Start by turning the humidistat on your central humidifier to the “off” position (or the position with the lowest percent of relative humidity, depending on the model that you have). You can typically find the humidistat installed above your humidifier on the return air plenum, though sometimes a central humidifier’s humidistat will be installed on the wall near your thermostat.

Step #2

After you have turned off your humidifier’s humidistat, you will next want to turn the bypass duct damper on the humidifier to the “Summer” position or close it off entirely depending on the model that you have. It is important to note, though, that some central humidifier models do not have bypass duct dampers, meaning that you may be able to skip this step entirely.

Step #3

Turning off the water supply to your central humidifier is the final step in shutting it off for the summer. If you aren’t sure how to cut off the water to your central humidifier, simply find the copper or plastic water line that is connected to your humidifier, follow it back until you find a valve, then turn the valve counterclockwise until it is all the way shut off.

Having turned off your central humidifier for the summer, it’s a good idea to go ahead and clean the humidifier, replace its water panel, and leave it out to dry until you are ready to start using it again.

Conclusion

Central humidifiers can be very beneficial during the heating season, but it is critical to turn them off once the weather warms up and you start using your AC unit again.
