Air duct cleaning may entail cleaning the components of forced air systems within the home. The parts that function to provide heat and air into the home may include fan motors, registers, drip pans, ducts, etc. Like any other part of the home, air ducts can collect dirt or be prone to other contagions.
In determining whether or not to have air ducts cleaned, there are several issues to consider when making the decision.
If mold is visible inside the ducts or on other components of the system, it may be time to have the air ducts cleaned. It is important to find out what is causing the mold to grow and correct this problem as well. If the source is not identified, the mold will return and the cleaning will be useless. The presence of vermin such as rodents or insects also may indicate a need for cleaning. A large build up of dust and other particles should also be cleaned out. This prevents clogging of the system.
Cleaning air ducts may also improve the efficiency of the heating and cooling system. However, it is recommended by the Environmental Protection Agency (EPA) that air ducts are only cleaned out of necessity and not routinely. It is important to note that when having air ducts cleaned, a qualified professional cleans all of the components of the system. If cleaning is not performed properly, re-contamination of the entire system may occur.
The cleaning process may involve specialized tools to dislodge debris. The debris is then removed with a high-powered vacuum cleaner. Chemicals may also be applied that are designed to kill any microbiological contagions. A sealant may also be applied to inhibit any mold growth. It is recommended that customers discuss all of their options with a qualified service provider to determine what works best for their home.
