Humidifier Maintenance and Cleaning Tips

Whole home furnace mounted humidifiers need some TLC!

Many modern homes include furnace mounted humidifiers to control the level of moisture in a home. They operate most often during the winter months in colder climates when humidity levels are lower and help prevent things like dry, itchy skin and static buildup.

There are a few different types of humidifiers, all require some sort of maintenance to ensure they are kept clean and to prolong their operational life. Humidifiers should be checked monthly, and power to your furnace should be disabled while cleaning. If your humidifier includes an evaporator drum or pads, ensure it is free of any type of buildup or scale. Clean with vinegar and water solution. If your unit uses a replaceable evaporative screen pad, they should be replaced every 6 months to a year depending on use. Ensure all hoses and manifolds are clear of any buildup or residue. Remember to turn the power to your furnace back on when done!

It is also a good idea to check the operation of your humidifier, and you can do so by monitoring it during furnace operation. Ensure water is flowing correctly or if the unit has a water tray, that the tray contains sufficient water. During testing, you may need to adjust the humidifier setting to a higher level temporarily to call for water in order to confirm proper operation. Remember to set it back to its original setting when done. If you experience any issues with humidifier operation or if repairs are necessary, it is best to contact a qualified technician to perform the work.
