Mold & Mildew Duct Treatment in Winter Garden, 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 Winter Garden, Horizon West, Hamlin, Oakland, Windermere, and the rest of west Orange County. The local SERP is dominated by the larger regional operators and HVAC contractors — all solid operators, but most run a tiered pricing model that climbs once a tech is on-site. We give one firm written quote up front. The bigger Winter Garden problem isn't dust — it's construction debris. Builders in Horizon West, Hamlin, Hickory Hammock, Waterleigh, and Independence almost never flush ductwork before turnover, so drywall fines and sawdust blow into the home for months. A post-construction cleanout in the first 90 days is the single highest-ROI HVAC investment a new Winter Garden homeowner can make.

Our process in Winter Garden

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 — Winter Garden

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?

Winter Garden 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.
