Homeowners :: Ventilation and Dehumidification

Adequate ventilation can cut down on the humidity in your home.

  • Use ventilation fans in kitchens and baths to control moisture. Check to make sure ventilation fans venting directly outside. In some cases the vent fan may have been installed to vent into the attic or become disconnected or blocked.
  • Your clothes dryer should be vented directly to the outside. The vent duct should be inspected to make sure it is attached securely to the dryer, is clear of obstructions (e.g. lint), and free from holes that leak air. Vent ducts should be cleaned at least once a year, and damaged vent ducts should be replaced.
  • Ask a contractor to check your heating and cooling system to make sure it is sized correctly and operating properly to remove humidity. If you system is too big or the airflow incorrect, your air conditioner will not remove humidity like it should.
  • If your home uses central air conditioning, consider installing an A/C vent in the humid space in your home and take advantage of the dehumidifying capabilities of your A/C system. This will also help with air circulation, improving airflow between humid parts of your home and drier parts.
  • In certain cases, adding a dehumidifier may be necessary
