How to Control My Home’s Humidity

The four seasons in the Delaware Valley come with variations in humidity throughout the year. For this reason, the answer to ‘How to control my home’s humidity’, could differ between winter and summer. In summer, you may need to dehumidify your indoor air. In winter, you may need to humidify the air to increase comfort and prevent overly dry skin. Beyond the weather, poor ventilation or missing vapor barriers can promote excessive moisture.

How to Control My Home's HumidityAir Quality Tools

  • Hygrometer
  • Humidifier
  • Dehumidifier

High Humidity Problems

High relative humidity within the home above 40% to 50% also reduces your comfort in hot weather. The air conditioner must work harder to cool humid air. As a result, your electricity bill increases.

  • Mold growth and odors
  • Paint peeling
  • Home structural damage
  • Metal corrosion
  • Respiratory system irritation

Low Humidity Problems

Low household humidity normally emerges as a problem in winter. Humidity is lower during this time of year, and your heating system will dry out the air as it runs.

When your home’s humidity goes below 30%, the dry air makes it easier for you to feel cold. Your body will lose heat through evaporation from your skin. Your most likely response will be to turn up the heat and thereby increase utility costs.

  • Dry skin and hair
  • Respiratory irritation
  • Static electricity shocks
  • Cracking wood floors
