Preventing Mold in Air Ducts

Air ducts are a prime target for mold growth. They can become easily contaminated and are often a breeding ground for rodents and other vermin. Besides visible mold growth, which can occur in the sheet metal of your heating and cooling systems, air ducts also produce extreme amounts of dust and debris. It is important to clean air ducts on a regular basis.

Prevent Mold

There are three main methods used to prevent mold from growing in air ducts: chemical treatments, careful environmental control, and manual cleaning.

Treatments

Chemical treatments for mold prevention usually range from $450 to $1,000. Common cleaning compounds are ethylene oxide, thymol, and orthophenyl phenol. It is important to make sure whatever company you hire to do chemical cleaning has a good reputation and the right equipment, because chemical cleaners are strong and can have adverse effects if not administered properly.

Environmental

Environmental control is the practice of maintaining a consistent level of humidity so that mold does not have the chance to form. This is done by regulating the climate control system and using a dehumidifier if necessary.

Cleaning

Manual solutions include simply scrubbing or vacuuming the ducts regularly. Keep in mind that this should be done as a preventative measure only - if there is already mold present, it is best to get a professional cleaning done.
