The answer to 'what does duct cleaning do' is that duct cleaning is the process of removing dirt, dust, and other contaminants from the ductwork in a home's HVAC system. This helps improve indoor air quality, increase energy efficiency, and extend the lifespan of the HVAC equipment.
During duct cleaning, a professional technician uses specialized tools and vacuums to thoroughly clean the air ducts, registers, and other components of the ductwork. This removes built-up debris that can circulate through the home, aggravating allergies and respiratory issues. Duct cleaning also helps the HVAC system run more efficiently, which can lead to lower energy bills and fewer repair needs.
