Aside from air conditioning and heating units, dehumidifiers, like those made by Amana, are an essential component of any household’s HVAC system. True to their name, dehumidifiers reduce the amount of humidity that can be found indoors, but only to a certain extent since too little humidity can cause wood chips and dry skin. Although a hygrometer can determine if a dehumidifier is needed at home or not, homeowners can look for signs of excess humidity instead.
Condensation found in the glass is usually the most obvious indicator, especially if it appears during a relatively warm season. However, condensation in windows and doors may also be caused by the inherent humidity from certain construction materials like cement. Mold spots, on the other hand, are definitely caused by excess humidity (if not by water leaks) and should be removed with the help of a dehumidifier. If there are no black or brown spots, then a musky or rusty smell should be a giveaway.
Homeowners should also visit their basement (if they have one) every now and then. White and grayish marks on the floor are likely caused by spring water from the ground, which in turn can be a source of humidity. This telltale sign is more apparent in homes that were built on a low plain or an old riverbed.
