When Is It Necessary to Clean Your Ductwork?


The Environmental Protection Agency suggests that you should clean your ductwork only when needed, and not on a regularly basis. However, certain circumstances may arise where cleaning your ductwork is necessary:

  • Mold growing inside the ductwork. Mold will begin to grow inside the ducts when an excessive amount of moisture is present. Mold releases spores into the air, which will travel through the ductwork and into your home. These spores will cause new mold growth and cause various health problems and allergy symptoms.
  • Ducts are infested with vermin such as rodents or insects. An infestation will leave your heating and ductwork filled with bacteria, feces, odor and other debris that the forced air pushes through the registers.
  • Ductwork is clogged with dirt, dust and other debris. The ductwork interior will naturally become a bit dirty. However, if an excessive amount of dust and debris are forces out of the registers when the furnace is on, you will need to clean your ductwork.

If your ductwork develops any of the above conditions, it could mean there is an underlying problem. For example, mold will continue to grow in the ductwork if the source of the fungus growth is not dealt with when the ducts are cleaned.

Once you have cleaned you ductwork, take the necessary precautions to keep them clean and functioning properly with the following steps.

  • Change your furnace filters regularly. A clogged filter will cause your furnace to work harder and wear it out quicker.
  • Use the highest efficiency rated filter recommended for your specific furnace.
  • Have your heating and cooling unit serviced by a reputable company at least once a year.
  • Regularly keep your home clean by vacuuming frequently. This will help reduce the amount of debris that slips into the ductwork via the registers and vents.
