Indoor Air Quality: Preventing Mold in Ducts in Miami Humidity

South Florida humidity is relentless. Moist air, cool duct surfaces, and dust combine to create the exact conditions where mold can start to grow in your ductwork and around your evaporator coil.

The good news: mold growth in ducts is largely preventable with consistent maintenance.

Signs mold may be an issue

• A musty or damp smell when your AC runs
• Visible dark spots around vents or the indoor unit
• Worsening allergy symptoms inside your home

Prevention starts with the basics

Keep your filter fresh, let your system run enough to dehumidify properly, and make sure condensation drains are clear. Regular cleaning of the evaporator coil and keeping dust out of the system all reduce the food source mold needs.
