Mold Remediation and Duct Deodorizing Ballwin MO

Eliminate Mold, Odors, and Contaminants from Your HVAC System

If your home has a persistent musty smell, allergy flare-ups, or signs of moisture near vents, mold may be growing inside your air duct system. At A Breathe-Rite Carpet & Air Duct Cleaning Co, we provide professional mold remediation and deodorizing services for HVAC systems in Ballwin, Missouri.

Mold inside ducts not only creates unpleasant odors — it also spreads spores into the air you breathe. Left untreated, this contamination can affect your health and damage your HVAC components. Our certified team safely removes mold and neutralizes odors using EPA-approved cleaning agents and professional equipment.

Signs You May Have Mold in Your Air Ducts

Our Mold Remediation Process

We follow strict industry standards to detect, clean, and treat mold inside air ducts. Our process is thorough and safe for homes with children, pets, and sensitive respiratory conditions.

Step 1: Inspection and Testing

We begin with a visual and odor-based inspection of your HVAC system. If needed, we use moisture meters or borescope cameras to identify hidden growth. We determine whether mold is active, dormant, or caused by recent water damage.


Step 2: Source Removal

Using HEPA-filtered vacuums and duct agitation tools, we remove all dust and debris where mold tends to grow. This is followed by mechanical scrubbing and suction of affected ductwork and HVAC components.

Step 3: Antimicrobial Treatment

We apply EPA-registered antimicrobial and fungicidal sprays throughout the affected duct system. These agents kill mold at the source and prevent future growth. All treatments are safe for indoor use and leave no harmful residue.

Step 4: Deodorizing

Our odor neutralizing process eliminates musty, sour, or mildew smells inside ductwork. We use non-fragrant deodorizers to restore a clean, neutral indoor air environment.

What Causes Mold in HVAC Systems?

Understanding the source of contamination helps prevent future mold problems. Common causes include:

  • High indoor humidity levels or poor ventilation
  • Water intrusion near ductwork (roof leaks, basement flooding)
  • Clogged AC drain lines or frozen coils
  • Uninsulated ducts in crawlspaces or attics
  • Dirty or infrequently cleaned air ducts

We help identify contributing factors and recommend corrective actions as part of our service.
