Commercial HVAC & Duct Mold

In offices, retail, healthcare, and hospitality buildings, mold in rooftop units, air handlers, and supply/return ductwork is a serious indoor air quality and liability issue. Condensate pan failures, poor drainage, liner degradation, and filter bypass allow moisture and organic debris to support mold growth that distributes spores every time the system runs.

Commercial systems are larger and more complex than residential split systems. Contamination may be localized to a single VAV box—or spread through main trunk lines serving multiple floors. Occupant complaints, OSHA or tenant concerns, and lease obligations often drive expedited remediation with strict containment and documentation.

Our team works with mechanical contractors and industrial hygienists when required, establishes containment and negative pressure appropriate to occupied buildings, removes or cleans contaminated liner and components per scope, and supports clearance sampling for property managers and insurers.
