The answer to 'why is my duct cleaning' is that there are several common causes for needing duct cleaning, such as excessive dust buildup, pest infestations, or mold growth. Symptoms include poor airflow, musty odors, and respiratory issues for occupants. The solution is to have a professional HVAC technician inspect and clean the ductwork, which can improve air quality and energy efficiency.
Homeowners should not attempt to clean their own ductwork, as it requires specialized equipment and expertise to access and thoroughly clean the entire system. Improper DIY duct cleaning can actually damage the system or spread contaminants. It's best to hire a reputable HVAC company that follows industry standards and uses high-powered vacuums and brushes to dislodge and remove debris from the ductwork.
