How to get rid of mold in air ducts?

The presence of mold in air ducts poses a significant threat to the health and well-being of occupants. Here are some easy steps to get rid of mold in air ducts:

Step 1: Identify the Source

Before embarking on mold removal, it’s most important to locate the source of the infestation. This involves inspecting air vents, ducts, and other potential breeding grounds for mold. Look for visible mold growth, musty odors, and signs of moisture damage, such as water stains or discoloration.

Step 2: Turn Off HVAC System

Once the source of mold has been identified, the next step is to shut down your HVAC system to prevent the spread of spores throughout your home. This will help to contain the infestation and make the cleaning process more efficient.

Step 3: Protect Yourself

Step 4: Clean and Disinfect

Thorough cleaning and disinfection are essential to eliminate mold growth. For non-porous surfaces, such as metal ducts and vent covers, a bleach solution of one part bleach to 16 parts water can be used. For porous surfaces, such as fabric air filters, a solution of one tablespoon of laundry detergent, half a tablespoon of baking soda, and one cup of water can be effective.
