Managing Indoor Humidity in Concord During Winter

Many potential issues impact your home during the winter months. Indoor humidity levels can cause a variety of risks, whether you’re dealing with excessively damp or dry air. Homeowners need to know how to achieve effective humidity control. Winter in Concord, CA, calls for the following actions.


Make Sure Your Ducts Are in Working Order

Damaged ductwork can lead to serious humidity issues by allowing warm air to escape and pulling in unconditioned air from outside. This can increase dryness, as the cold air doesn’t hold much moisture. A professional inspection can help reveal any potential issues and ensure balanced airflow that maintains comfortable humidity.


Clean Any Window Condensation

You might notice moisture condensing on window glass during winter. This is a clear sign that indoor humidity is too high. Left alone, that water drips down and can lead to mold growth. It’s best to wipe away this condensation whenever you notice it, and leave blinds open to promote air circulation that stops droplets from forming in the first place.


Seal Leaks to Prevent Water Intrusion

Even small gaps around doors and windows can let drafts enter your home. If this happens during rainy weather, it can increase the humidity in your home. Seal vulnerable areas with caulk or weatherstripping. This not only helps achieve humidity control but also prevents heat loss.


Consider Installing a Whole-Home Humidifier

If you’re dealing with ongoing dryness in your home, a whole-home humidifier could be just what you need. This equipment integrates with your HVAC system to provide a consistent humidity level.


Avoiding low humidity helps prevent an uncomfortable environment and dry skin and hair. It also protects wooden flooring and furniture, which can crack and split if humidity stays low for too long.
