Posted on: June 2, 2015 | by: HVAC.com July 26, 2017

Indoor environments with excessive humidity levels are uncomfortable and pose a number of problems to your health and home.


Luckily, humidity problems can be remedied through the use of a dehumidifier, either a whole-home model or portable unit that can be used specifically in problem areas of the home. Be on the lookout for the symptoms below which indicate excess moisture, as they are signs you need a dehumidifier in your home.


But you are probably wondering:


“If the temperature is comfortable in my house… how do I know if I need a dehumidifier?”


What are the signs?


    1. Condensation on windows and glass doors

      When an indoor environment is too humid, condensation will collect on glass in the room. It can look like fog on the windows or you may even see streaks of water droplets sliding down your window panes as moisture collects.


    2. Mold spots on walls and ceilings

      The cause of some mold growth is easy to determine, such as that growing around a leaky toilet or under a leaking sink. When there is excess moisture in the air inside your living areas, mold can grow on surfaces like walls and ceilings. Bathrooms are a typical trouble spot, as proper ventilation is not always in place to divert the steam created by running hot water. Steam rises and settles on the ceiling and in the corners of the walls, so be sure to keep an eye on these areas. Moisture can also be trapped in closets, basements, and other poorly ventilated areas of the home, leading to mold growth.


    3. Musty odors

      A musty odor is a tell-tale sign that mold and mildew growth is present. Excessive humidity in the home can cause mold growth, leading to this odor.

    4. Ground water dampness

      Water run-off associated with the rainy season can lead to excess moisture in the home. If water run-off is not diverted properly, it can flow back towards your home, causing moisture problems in basements and other areas of the home.

    5. Water stains

      Water stains on walls, ceilings, floors, and other surfaces are a red flag for excess moisture in the home. As humidity builds up in the home and gathers on surfaces, it will create water marks and stains.
