Should You Turn Your Humidifier Off In The Summer

During the summer months, turning off your humidifier can have several benefits. The air is already naturally moist in the summer, therefore using a humidifier can be unnecessary and even counterproductive. In fact, running your humidifier during the warmer months can reduce the efficiency of your air conditioner and cause your energy bills to increase.

If you have a central or whole-home humidifier, it’s crucial to make sure that the bypass duct damper is in the summer position to avoid the flow of humidity into your home. If you have a portable humidifier, you can simply turn it off and store it away until next winter. By turning off your humidifier during the humid summer months, you can maintain a comfortable living environment without compromising on your energy bills.

By turning it off, you will not only save costs but also avoid any potential comfort issues caused by excess humidity.


Whether or not to turn off your humidifier during the summer months depends on your specific situation.

Remember to properly maintain your humidifier by regularly cleaning or replacing the water panel/filters, checking the water supply and valves, and getting regular humidifier service as needed. By doing so, you can ensure the effectiveness and service life of your humidifier while also potentially saving on energy bills and improving your overall indoor comfort.
