Does duct cleaning work?

Yes, duct cleaning can be effective in certain situations, particularly when there is visible mold growth, an infestation of rodents or insects, or an excessive buildup of dust and debris in the ducts. In these cases, duct cleaning can help improve air quality and reduce allergens or irritants.

However, if there’s no clear contamination in your ducts, the benefits of duct cleaning are less clear. The Environmental Protection Agency (EPA) suggests that routine duct cleaning is not always necessary, as ducts in most well-maintained HVAC systems may not accumulate enough debris to impact air quality or HVAC efficiency significantly.

That said, people with respiratory issues or allergies may feel that duct cleaning improves indoor air quality. It’s also worth noting that while ducts themselves may not always need cleaning, regular maintenance of other HVAC components—like filters, coils, and blower motors—can help keep systems efficient and air quality high.
