The Environmental Protection Agency (EPA) recommends that you have your air ducts, heating and cooling systems inspected first by a Professional Heating and Cooling Contractor. In many cases, this service is unnecessary. If, after this inspection, you discover that your air ducts have substantial visible mold, dust, dirt, and other contaminants or a musty odor, a professional will recommend duct cleaning. This is especially important if someone in your household suffers from asthma, allergies, or other symptoms that may be related to indoor air pollution. Although duct cleaning alone has never been shown to actually prevent health problems, it is an important step in a whole-house air cleaning strategy.
Much of the dirt and dust that accumulates in the ducts adheres to the duct surfaces and to the furnace and air conditioning components. This does not mean that it necessarily becomes airborne and enters our breathing space. However, this accumulation is a perfect breeding ground for mold, bacteria, dust mites and other fungi that are definite sources of indoor air pollution. There are many other sources of indoor air pollution that can be controlled with the whole-house duct mounted air cleaning systems available through Nature’s Home.
