Insurance for Duct Cleaning Services

What underwriters look at

Duct cleaning creates a distinct kind of liability exposure because the work is meant to improve indoor air quality, and when a customer later develops respiratory symptoms or discovers mold, the cleaning company is often one of the first parties they suspect. Even when a technician did the job correctly, proving that mold or dust wasn't dislodged and redistributed through the system during cleaning can be a difficult defense, especially if the customer files a claim weeks after the service when symptoms first appear.

The physical process itself carries damage exposure too. High-powered vacuum and negative-air equipment connected to a home's ductwork can dislodge loose connections, and a technician working through a register can accidentally damage drywall, flooring, or the ductwork itself. Commercial jobs in restaurants and office buildings add exhaust and rooftop unit access, along with the possibility of temporarily shutting down HVAC service in an occupied building, which can create business-interruption friction with the customer if something goes wrong.

Because duct cleaning is frequently marketed alongside health and air-quality claims, companies that overstate results or fail to document pre- and post-service conditions expose themselves to disputes beyond simple property damage. Carrying solid general liability coverage, along with clear documentation practices and equipment coverage for vacuum trucks and negative-air machines, helps duct cleaning companies respond credibly when a mold or air-quality allegation surfaces.
