Duct cleaning generally refers to the cleaning of various heating and cooling system elements of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans, fan motor and fan housing, and the air.

Duct cleaning contractors use large, portable or truck mounted vacuum collection machines to suck smut and debris out of your ductwork. First they must fasten the vacuum collection device’s large pipe to a duct close to the air handler- the heart of your HVAC system. The typical duct cleaning process approximately takes 2 to 4 hours of a single family consisting of at least two technicians. People having pets in their homes or those who are living in older homes may take a long time to clean. A professional air duct cleaning eliminates the dirt and debris. An odor oxidizer can be applied to breakdown any remaining chemicals that cause smoke odors.

Many people ask this question that they want to know is air duct cleaning a complete waste of money? The National institute of health says there is no enough proof to determine if duct cleaning actually improves inner air quality (IAQ).The ductwork in your heating and cooling system continuously collects dirt, dust and debris while idle and while in operation. So it means that it has very harmful consequences on your health when you turn your system on. Because those particles can spread around in your surroundings and eventually impact your health. Air ducts frequently contain destructive contaminants and micro-organisms too.  These comprise pet dander, bacteria, pollen, mold and mildew, and similar toxic agents.

Detailed cleaning of the air ducts removes all the dust and odor trapping particles, resulting in a fresher smelling home.
