Indoor pollution has become an issue of growing concern and increased visibility. There are many companies that are marketing products and services to take care of your indoor pollution. Duct cleaning is referred to the cleaning of various heating and cooling system components 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 handling unit housing.

Knowledge about the potential benefits and possible problems of air duct cleaning is limited. As the conditions are different in every home, hence it is difficult to generalize about whether or not air duct cleaning in your home would be beneficial.

While installing your heating and cooling systems, if not installed or maintained properly they may become contaminated with dust particles, pollen and other debris. If moisture is present the potential for microbiological growth is increased and spores from such growth may be released into the home's living space. These contaminants are very harmful as they may cause allergic reactions or other symptoms in your body. So if you decide to have your ducts cleaned , make sure that the service provider is well qualified to do the job and also see to it that they agree to clean all components of the system, both cooling and heating or else these components will get re-contaminated thus negating any potential benefits.

If the service provider fails to follow proper duct cleaning procedures, duct cleaning can cause indoor air problems like for example an inadequate vacuum collection system can release more dust, dirt, and other contaminants than if you had left the ducts alone. An inadequately trained service provider can damage your ducts or heating and cooling system, possibly increasing your heating and air conditioning costs or forcing you to undertake difficult and costly repairs or replacements.

The services provided by these service providers are of different price range depending on the services offered, the size of the system to be cleaned, system accessibility, climatic region, and level of contamination.

The service providers may apply chemical biocides, designed to kill microbiological contaminants, to the inside of the duct work and to other system components and some providers may also suggest to apply chemical treatments such as sealants to encapsulate or cover the inside surfaces of the air ducts and equipment housings as it will help to control mold growth or prevent the release of dirt particles or fibers from ducts. You should do a thorough research and know about the pros as well, the cons of using such biocides or chemical treatments in your airducts.They should be able to fully provide you all the information about the products they are going to use.

So, be careful before you invest and look for a trained and licensed service provider for Duct Cleaning.
