Preventing Mold in Your Air Ducts: Essential Tips for New London Homeowners

Mold growth in residential air duct systems is a widespread problem in coastal Connecticut, and New London homeowners are particularly vulnerable. The combination of high humidity from Long Island Sound, temperature fluctuations between seasons, and aging housing stock creates ideal conditions for mold colonization inside ductwork. Once established, mold releases microscopic spores that your HVAC system distributes to every room in your home, potentially causing allergic reactions, respiratory problems, and other health issues.

The most common areas for mold growth in New London homes are where ductwork passes through unconditioned spaces with high moisture levels. Basements, crawl spaces, and attics are prime locations, especially in older homes in neighborhoods like Winthrop, the Hempstead District, and along the waterfront where proximity to the water keeps ambient humidity levels elevated year-round. Even homes with newer construction can develop mold in their ductwork if the system is improperly sized, the condensate drain is not maintained, or humidity control is inadequate.

Professional air duct cleaning is the most effective first step in addressing mold contamination. Our technicians use HEPA-filtered equipment to safely remove mold colonies and spores from the interior surfaces of your ductwork without spreading contaminants to other areas of your home. After the physical cleaning, we apply an EPA-registered antimicrobial treatment that creates a protective barrier against future mold growth. We also identify and address the moisture sources that allowed the mold to develop in the first place, such as condensation on duct surfaces, leaky connections, or inadequate insulation.

VENTNEX recommends that New London homeowners have their ductwork inspected for mold at least once a year, ideally in late spring before the humid summer months begin. Early detection and treatment are far less costly and disruptive than dealing with an established mold problem. Our New London team is equipped with moisture meters, borescope cameras, and air quality testing equipment to provide a thorough assessment of your duct system's condition.
