Air ducts naturally accumulate sizeable deposits of dust and other contaminants over a period of years.
And those dirt deposits can reduce the efficiency of your heating and air conditioning system and even cause physical discomfort or illness by degrading the quality of air you breathe indoors.
Plus, dirt deposits in your air ducts actually act as food for organisms such as dust mites.

Many homes have inefficient filters, which trap less than 10 percent of the particulate that is circulated in the system. If not trapped by the systems air filter, the particulate accumulates in the ductwork and on the internal components of your furnace or fan coil.
Cleaning your duct work eliminates those contaminates with the following benefits:
