Why Too Much or Too Little Humidity is Bad for Your Home

Are the humidity levels in your home optimized for you, your family members, your pets and the finishes in your home? If you’re like most homeowners, you don’t think about humidity unless it’s hot and humid outside. Unfortunately, humidity levels that are too high or too low in your home can make you feel unwell and damage your wood furniture, floors and even your drywall. the good news is that an HVAC professional can determine the best ways to control your indoor humidity levels and install the equipment.

High Humidity Level in Your Home

If the relative humidity inside your home is above 50 percent, it is considered to be too high. At these levels, you may notice moisture drops on your windows and walls, especially in kitchens, bathrooms and basements. When humidity levels are high, you may feel hot and sticky even when your air conditioner is running. Your cloth furniture and carpets may also feel damp. If high indoor humidity levels aren’t controlled, you could end up with mold and mildew growth in your carpets and furnishings as well as on your drywall and even behind your walls.

Low Humidity Levels in Your Home

Low humidity levels are considered to be below 30 percent. While this is most common in the winter, it could occur in the summer if your air conditioner cycles too often or runs for too long. Your family members may experience dry mucous membranes, and your indoor air will feel colder than the thermostat setting. Low humidity levels also contribute to indoor bacteria and virus growth, which can result in an increased frequency of illness.

While having low humidity levels won’t cause mold or mildew, they can damage your home, resulting in cracked or split wood floors, wood moldings and even wooden chairs and tables. You may also notice that your wallpaper starting to separate from your drywall and curl around the corners and edges. The good news is that increasing your home’s humidity levels can stop this damage.

How to Control Humidity Levels in Your Home

Home humidity levels are controlled with humidifiers and dehumidifiers. These can be separate systems that are not connected to your HVAC system, or they can be added as an additional feature of your heating and cooling system. The great news about these systems is that once they are installed by an HVAC professional, they will help keep your home’s humidity levels in the optimal range between 30 and 50 percent, and all you’ll have to do is to periodically clean the drain pans and change the filters if you don’t have them included in your HVAC maintenance plan.
