Is It A Cold Or Is It Mold?
During the winter, being sealed up inside also means that you are also sealed in with any mold that may exist in your home. Damp basements, bathrooms and closets can all harbor mildew and mold. When you are indoors for the cold season with the windows closed and the heat running, your exposure to allergens will spike.

Attic ventilation is critical to maintaining even attic temperatures throughout the year. In the summer, proper ventilation vents excess heat. In the winter, it prevents the buildup of excess moisture and accumulation of water condensation.
If you live in New York, New Jersey or anywhere in the Northeast, you know that this summer has been a bad season for allergy sufferers. Pollen counts have been through the roof.
