Duct Sanitization
EPA-registered antimicrobial treatment to eliminate bacteria and viruses.
About Duct Sanitization
Sanitization is a finishing step, not a substitute for cleaning. Applying an antimicrobial to a duct system still full of debris simply coats the debris. We only sanitize after source removal, when the surfaces are actually clean and the treatment can reach and remain on them.
We use EPA-registered antimicrobial products labeled for HVAC surfaces, applied as a fine fog through the system so the treatment reaches trunk lines, branches, and the plenum evenly. It targets the bacteria, mold spores, and mildew that survive on damp interior surfaces, particularly in humid climates and homes with a history of condensation problems.
This is the right add-on after water intrusion, after a mold finding, when someone in the household is immunocompromised, or when an odor persists after cleaning. We explain the product used, the dwell time, and when the space is safe to reoccupy — typically a short wait after application. At $79 per system it is the most common add-on to our whole-home package.

How the appointment works
- 1Inspection & walkthrough
We arrive in the 9am–6pm window, protect your floors and furnishings, then inspect the cleaned duct surfaces, coil, and plenum with an HD camera and show you what we find before any work starts.
- 2Containment & setup
Negative pressure is established with a truck-mounted or portable HEPA vacuum so debris travels out of the building, not into your rooms.
- 3Agitation & extraction
Rotary brushes, air whips, and compressed-air tools break loose the bonded dust and buildup while the vacuum pulls everything out under continuous suction.
- 4Verification & report
We re-inspect on camera, take after photos, walk you through the results, and only then do you pay the technician at your doorstep.

Common questions
Do I actually need duct sanitization?+
Only if there is a reason — microbial growth, a musty smell, or moisture in the system. We inspect first and will tell you when you do not need it.
What product do you use?+
An EPA-registered antimicrobial, applied by fogger after the ducts are physically cleaned. Sanitizing dirty ducts does not work.
Is it safe for children and pets?+
Yes, once the treatment has dried. We give you a specific re-entry time before we leave.
