"The U.S. Environmental Protection Agency ranks indoor air pollution as one of top five environmental threats to public health. Studies have shown that pollutant levels indoors are often 2-5 times higher than those found outdoors. Since people spend the majority of their time indoors, the home, school or workplace are locations where exposure to indoor contaminants is the highest concern.

Air ducts can be found in many homes and condominiums. They are located in the ceilings, walls, and floors and carry air through the heat and air conditioning to the various rooms of your home.Over time these ducts can become contaminated with dirt, pollen. dust mites, and other undesirable things that are not especially good to breath in. This can be a real problem for people suffering from allergies, asthma, and other respiratory problems, and is generally not healthy for anybody else.

Ducts like this can be a serious threat!

Many contaminants that contribute to poor indoor air quality are found in the HVAC System. In an October 1997 report the EPA stated that if not properly maintained, air duct components may become contaminated with particles of dust or other debris. If moisture is present, the potential for microbiological growth is increased and mold spores may be released in the indoor environment. Cleaning a dirty and improperly maintained HVAC System will Significantly improve indoor air quality."
