Humidifier on Central Furnace

    Winters in Indiana are very dry, which causes your skin to dry out and is harder on your lungs.  This is why some homeowners install humidifiers on the central forced air furnace.  Unfortunately, adding moisture to the home can encourage mold growth at windows and in the ductwork.  Also, many homeowners don't turn the humidistat to the correct setting, which will also increase the chance for mold growth.  
    If you do use a humidifier, then have the ductwork, furnace, and humidifier cleaned annually to mitigate the spread of mold.  Also, monitor humidity levels in the house with a hygrometer.  Humidity levels should be no greater than 50%.
