Whole-house humidifiers are working hard during the dry North Texas winter to keep indoor air healthier and warmer. Your HVAC professional can get your humidifier ready for the season during your furnace’s annual tune-up, but regular ongoing maintenance is essential for the efficient operation of your humidifier.
Inspect your whole-house humidifier once a month. Look for and remove mold and mineral buildup, and check for leaks on and around the unit.
Replace the water panel
The water panel, pad or filter, depending on the model of humidifier you have, needs to be replaced at least once a year, or more often if you have hard water or keep your home particularly humid. Mineral buildup in the tiny holes prevents the air from flowing through the humidifier and will make the system operate inefficiently.
Level the distribution tray
If the water distribution tray isn’t level, the water won’t flow down the water panel properly.
Check the solenoid valve
The solenoid valve releases water into your humidifier. To check it for correct operation, make sure your furnace is on and turn off your humidistat, then wait a few moments and turn it back on. You should hear the solenoid valve click, followed by water running through the plastic tubing.
Clean the orifice
The orifice is located just below the solenoid valve and regulates the flow of water into the distribution tray. If its small hole becomes clogged with mineral buildup, remove it with a thin needle.
End of season
At the end of the humidifying season, thoroughly clean your humidifier and close the seasonal damper.
