The Benefits and Drawbacks of Air Duct Cleaning

Air duct cleaning is a process that can help enhance the performance and longevity of your HVAC system. It can also reduce the risk of hazardous diseases, but it is not always possible to do a visual inspection. The EPA does not recommend air duct cleaning in most cases, but they do suggest that ovens, stoves, and chimneys be inspected and serviced before each heating season to protect against carbon monoxide poisoning. Studies suggest that cleaning dirty cooling coils, fans, and heat exchangers can improve the efficiency of heating and cooling systems.

However, there is little evidence to indicate that simply cleaning the duct system will increase system efficiency. Cleaning dirt and debris from HVAC components will improve the efficiency of your HVAC system, but it is important to consult a professional before making a decision. The most effective way to prevent air pollution is to stop water and dirt from entering the system. If you have recently purchased a home, it is wise to clean your ducts and tune up your system.

Some service providers may suggest applying chemical treatments (sealants or other encapsulants) to encapsulate or cover the interior surfaces of air ducts and equipment housings. This can help control the formation of mold or prevent the release of dirt particles or fibers through the ducts. If enough dirt and moisture are allowed to enter the duct system, there may not be a significant difference in the speed or degree of microbial growth in internally lined or bare sheet ducts. It is essential to commit to a good preventive maintenance program to minimize duct pollution.

Sealants should never be used on the wet lining of ducts, to cover actively growing mold or to cover dirt in ducts, and should only be applied after cleaning in accordance with NADCA or other appropriate guidelines or standards.
