Cleaning Mold Out of Duct Work

Mold spores inside your air ducts can easily spread throughout your home when the HVAC system is in use. Not only is mold unpleasant, but may be dangerous to your health. Below are the signs you have a problem, and the steps it takes to help you keep your system clean.

Can Mold Get in Air Ducts?

Yes, mold can infiltrate your HVAC air ducts and lead to poor indoor air quality. Risks include:

  • Increased allergy symptoms.

  • Health problems like headaches, irritated nose and throat, nausea, respiratory illness, skin rashes, and itchy eyes.

  • Rotten, stale, or musty odors in the home.

Once a single spore finds the right humid condition, it can grow rapidly. It’s vital that homeowners understand their HVAC system and have it inspected and cleaned regularly to prevent mold.

How Does It Get There?

A prolonged relative humidity level above 60% in your home combined with warm air makes for ideal conditions for mold growth. So a damp and humid air duct is susceptible to mold. When your furnace or ac kicks on, your air ducts can distribute mold spores throughout the home.

How to Clean Mold Out of Duct Work

By the time a moldy odor has set in, the mold infestation has grown and will require professional removal from a mold specialist. It’s important that owners do not attempt to clean or remove mold on their own, as it can be dangerous and may cause more harm than good.

How to Clean Duct Work

Air ducts are easy to clean with the right tools and know-how. A standard air duct cleaning will remove dust and debris from your ductwork.
