When is air duct cleaning recommended?

• In certain situations, air duct cleaning is advised by the EPA. According to its site, you should consider professional air duct cleaning services if you see any of the following dangers:

• Visible mould inside your air ducts or on other components of your cooling and heating systems.

• Evidence of rodents or insects inside your air ducts.

• Partially or completely clogged air ducts, filled with excessive amounts of dust and debris.

• Dust and debris released into your home through the supply registers.

• These air pollution dangers certainly do need to be remedied with a professional cleaning, perhaps without the follow-up chemical sprays, and the larger issue is discovering and remedying the cause of mould and mildew.

• Broken ducts resulting in water seepage need to be replaced to eliminate the cause of mould or mildew that can make you and your family sick.

• The EPA says that it is normal for return registers to get dusty because it is pulling dust-laden air through the grates on a regular basis.

• Dusty registers are not always an indicator that your entire air duct system needs cleaning. Simply vacuum — or remove and clean — your return registers at this time of year to improve your indoor air quality, cut down on allergens and provide a better appearance on these visible facets of your rooms.
