Over time, the duct system in your home may become contaminated with particles of debris, dust and pollen. In addition, the potential for microbiological growth is increased when moisture is present. These contaminants in the duct can be distributed throughout the home, and may cause reactions or other symptoms when exposure occurs.

The EPA recommends that you have your duct system cleaned if it is dirty. You should consider having the ducts cleaned if there is visible mold growth inside the surface, ducts are infested with vermin (rodents or insects) or if your ducts are clogged with excessive amounts of dust, debris and particles that can be released into the home.
Various types of duct cleaning machines and technologies are in use by heating & cooling contractors and other service professionals. The entire system, including ducts, plenums, registers, the blower, and the indoor coil should be cleaned during the process. Special chemicals are sometimes used to treat biological growth. In addition, some duct service professionals offer a sealing process, which makes the duct system less prone to contamination, while also eliminating energy-wasting leaks.
