Mold & Mildew Duct Treatment in Orlando, FL

If you smell a musty 'dirty sock' odor when the AC kicks on, see black specks around your supply vents, or notice unexplained allergy flare-ups — there's a strong chance mold is growing inside your Florida ductwork. Our antimicrobial duct treatment uses EPA-registered fog to kill mold spores at the source, then we sanitize the entire HVAC system so it stops recirculating spores into every room.

Bastion Duct Solutions provides air duct and dryer vent cleaning across Orlando and the surrounding Orange County market — Lake Nona, Dr. Phillips, Winter Park, Baldwin Park, College Park, Apopka, Ocoee, and the Disney-area short-term rental belt. Orlando's mix of pollen, pet dander, new-build drywall dust, and 9-month AC season settles deep in residential ductwork. Vacation rental hosts in particular benefit from fast-turn cleanings between guests; every cleaning is documented with before/after photos and finished with optional EPA-registered antimicrobial fog.

Our process in Orlando

1. Inspect for Mold: Camera inspection of the supply runs, evaporator coil, and return plenum to confirm what we're dealing with.
2. Deep Clean First: Mold treatment is only effective on clean surfaces — we always recommend pairing with full duct cleaning.
3. Antimicrobial Fog: EPA-registered antimicrobial introduced as a fine fog while the blower runs, coating every interior surface.
4. Dwell & Ventilate: 30-minute dwell time, then we ventilate the home before handing it back to you.

Mold & Mildew Duct Treatment FAQs — Orlando

Is the antimicrobial fog safe for kids and pets?

Yes — we use EPA-registered formulas approved for occupied spaces. We still ventilate the home after treatment and ask you to wait 30 minutes before re-entering.

Will this fix a major mold problem in my AC?

Surface mold in the ducts, yes. If mold is growing on the evaporator coil itself or there's water damage in the air handler, we'll flag it and recommend HVAC service first.

How long does the treatment last?

Orlando humidity means spores can return — most homes benefit from re-treatment every 2–3 years alongside their regular duct cleaning.

Do I need a mold test first?

Not for surface treatment. If you suspect a structural mold problem, hire a licensed mold assessor before any cleaning.
