HVAC Duct Mold Removal: When Is It Necessary?

Mold, while found in virtually all places, can be a hazard to your health in excess concentrations. And, as water damage restoration experts from Rytech Nashville explain in the following Q&A, mold does not have to be seen to put you at risk.

Q: Is it possible for mold to grow in a home’s HVAC system ductwork?

Rytech Nashville: Absolutely. When your evaporator coil works correctly, however, condensation forms on the outside of the unit, and the ducts stay dry. When your system is not performing at its best, moisture may build up inside of the air ducts. This can also happen when the ductwork has been damaged, which allows moist air to circulate within the ducts.

Q: How can I tell if there is mold in the ductwork?

Rytech Nashville: When you have moldy air, one of the first things you might notice is a musty smell throughout your house when the HVAC system kicks on. You can also take a flashlight and look into an accessible air duct. Mold may look like irregular splotches or dust clinging to the floor and wall of a vent’s interior. Vent cleaning is often recommended as part of water damage restoration services if the home’s attic, crawlspace, or HVAC system has been compromised.

Q: What are some potential health hazards of airborne mold spores?

Rytech Nashville: There is almost certainly some mold in every house. This is usually confined to a small space and, unless disturbed, poses no threat. Airborne mold, however, can cause or worsen asthma, COPD, or other respiratory disorders. Children and the elderly are usually affected more than everyone else, so if you have very young or aging family members, you must pay careful attention to the air inside of your home.


Q: How can I get rid of mold in the air?

Rytech Nashville: If you are scheduled to receive water damage restoration services, ask your onsite technician about ductwork mold removal. Even if the ductwork was not affected or you have not suffered damage during recent storms, it will not hurt to have it inspected. A certified technician can perform a thorough evaluation and cleaning using specialized tools designed specifically for the job. If you suspect mold anywhere in the home, do not attempt to remove it yourself. Mold removal is not a DIY project. Done incorrectly, a bad situation can be made worse.

Q: What are some ways to prevent future mold growth?

Rytech Nashville: That depends on the cause. If your home has incurred water damage, restoration of the affected areas, which includes a complete drying and replacement of water-logged materials, can help. The most effective way to reduce mold in the ductwork is to simply have the unit maintained regularly by an HVAC professional and to check for damage and system malfunctions periodically.
