HVAC and duct mold in Novato, CA
Mold can grow in drain pans, on coils, and in ducts, especially ducts running through damp crawlspaces. The EPA advises not running a system you suspect is contaminated. Here's what that looks like in Novato, what to do, and how to get connected with an independent, licensed local provider.
HVAC and duct mold in Novato: what we see
Many Novato homes have forced-air systems, often with air conditioning given the warmer inland climate. AC coils and drain pans can grow mold if condensate lines clog.
The local picture
Heating systems in local homes. House age and type determine what heating systems and ducts are common. Novato has largely 1950s–1980s tract and ranch homes, many on slab foundations, plus newer subdivisions, hillside homes off San Marin Drive and Indian Valley, and older homes near Old Town.
Conditions vary a lot from street to street in Novato, so a provider should assess your specific home.
