The answer to 'what is duct cleaning' is duct cleaning is the process of removing dirt, dust, and other debris from the ductwork in a home's HVAC system. This helps improve indoor air quality, increase energy efficiency, and extend the life of the HVAC equipment.
During duct cleaning, a professional technician uses specialized tools and equipment to dislodge and remove built-up contaminants from the interior surfaces of the ductwork. This includes the main supply and return ducts, as well as any branch lines or vents. The debris is then vacuumed out, leaving the ductwork clean and clear.
