After a thorough mechanical cleaning, some duct systems—particularly those in older Austin homes, properties that have experienced water intrusion, or homes with heavy pet or smoke odors—benefit from a targeted sanitizing treatment. William & Sons Austin Air Duct Cleaning applies EPA-registered, water-based antimicrobial agents through a ULV (ultra-low volume) fogger that distributes a fine mist through the entire duct network, reaching surfaces that mechanical brushes cannot contact. The sanitizer neutralizes bacteria, mold spores, and allergen proteins that remain on duct walls after extraction.
Our deodorizing treatment uses encapsulating odor-neutralizing agents rather than masking fragrances, so smells from mold, pets, cooking, or tobacco are chemically neutralized at the source rather than temporarily covered. The fog disperses uniformly through supply and return branches, coating interior duct surfaces and evaporating without leaving wet residue. The process takes roughly 30–45 minutes after the mechanical cleaning is complete and requires the HVAC system to remain off for a short dwell period before the first post-service run-through.
Sanitizing is always performed after—not instead of—thorough source-removal cleaning. We will never apply sanitizer to a dirty duct system, as coating debris-laden surfaces provides no lasting benefit. This service is especially popular with Austin homeowners who are moving into a previously occupied home, have recently dealt with mold remediation, or simply want the highest level of indoor air quality assurance.

Common Questions
Is the sanitizing fog safe for my family and pets?
Yes. We use EPA-registered, water-based antimicrobial formulations that are approved for use in occupied residential buildings. We ask that occupants and pets stay clear during application and for the brief dwell period immediately after, but there's no extended evacuation requirement.
How long will the sanitizing treatment last?
The antimicrobial coating typically remains effective for 3–6 months, after which normal HVAC operation and dust accumulation gradually diminish its potency. Pairing it with regular duct cleanings every few years keeps your system in the best possible condition.
