HVAC - Humidifiers

Humidifiers add moisture to the air in your home allowing you to feel more comfortable at lower thermostat settings.

Care and Maintenance Tips Maintenance

  • If you selected the option to have a humidifier installed in your home, it will require annual maintenance to run at peak performance.
  • The water panel evaporator and unit filtering system should be changed and cleaned annually prior to the start of the Fall season. See your owner's manual for instructions or contact your HVAC contractor to schedule service.
  • When replacing the Water Panel Evaporator do not clean the grit out of the bottom of the tray. This grit provides smooth drainage for the water running down the evaporator.


  • Operate the humidifier during the winter months while you are running the furnace. Start with the unit set at the number 5 (or medium-level) setting.
  • Turn off the humidifier when you use the air conditioning. The additional moisture can cause a freeze-up of the cooling system. There is ample ambient moisture in summer air; if your humidifier adds more, it can overwork the air conditioner and reduce its cooling effect.

Frequently Asked Questions

Q: Why do I get shocked when touching things during the winter?
A: There is a lack of humidity in the home and the dry air creates static electricity, causing the shocks. Check the setting on your humidifier; the recommended setting is 35%RH.

Q: Why do I have water on my windows when using my humidifier?
A: If condensation develops on your windows, you should lower the control setting on the humidifier by one increment. The setting requirements change with the outside temperature; your manufacturer owner’s manual contains a table defining these.

Q: Why is my humidifier not working?
A: Turn the dial to "Test/Reset". Make sure the thermostat is set to "heat" to operate the furnace. If the unit still does not work contact your HVAC Contractor.
