Cleaning vs. Sealing Ducts

What is the difference between duct cleaning and duct sealing?

Duct cleaning removes dust, debris, mold, and allergens from inside the ductwork using specialized brushes and negative-pressure vacuums, while duct sealing closes gaps, holes, and loose connections in the duct system to stop conditioned air from escaping. Cleaning primarily improves indoor air quality, while sealing improves energy efficiency and airflow by keeping heated or cooled air inside the ducts instead of leaking into attics or walls. Many homes benefit from both services together. Green Home Services performs duct cleaning and sealing throughout San Antonio and Austin.
