When Is Duct Cleaning A Neccesity?

Over time, the ductwork in your heating and cooling system will accumulate dirt and other debris. A thorough professional duct cleaning may be needed to improve your HVAC system’s performance and increase the quality of your indoor air. The U.S. Environmental Protection Agency reports that duct cleaning has not been proven to prevent respiratory problems or any related types of health issues. However, under circumstances such as the following, the EPA does recommend a thorough professional duct cleaning.

Ducts show an excessive amount of mold or mold is visible on HVAC system components.
Make sure anything identified as mold actually is mold. Laboratory analysis of a sample of the substance may be necessary to establish if it's mold or something else.

If you have your ductwork cleaned, also fix leaks or other problems that promote mold growth.

Ducts are infested with insects, rodents, small animals or other vermin.
The nests of mice, rats, squirrels, insects and other pests can build up in ductwork, causing air blockages and increasing the presence of airborne contaminants. Small particles of the nests themselves can end up in your indoor air, along with animal droppings, tiny insect parts, hair and other unpleasant materials.

Ducts are clogged with dirt and debris that is being circulated back into your home’s indoor air.
A severely clogged ductwork system will not circulate conditioned air properly and will inevitably release dirt and other material back into your home’s indoor air. If your ductwork system is clogged so badly that air flow is restricted, the ducts should be professionally cleaned.

Hire qualified cleaning professionals with credentials such as membership in the National Air Duct Cleaners Association (NADCA). Be cautious of contractors who make overly optimistic claims of the benefits of duct cleaning; many of these claims may not be fully supported by facts. Ask questions and check references before hiring any contractor.
