Improve Air Flow Balancing with Duct Sealing

Improve Air Flow Balancing with Duct Sealing

Recently, ACHR News published an article about the importance of air flow balancing for in homes and buildings. However, air flow balancing alone is not the best solution.

If the ductwork is not properly sealed, then there will be air leaks (small holes, cracks, seams) in the ductwork that will cause conditioned air to leak out of the ductwork and not reach the desired room/space in a home or building. This duct leakage can cause the poor airflow you might notice at a register/vent.

Airflow Fundamentals

For airflow to occur, there must be both:

  1. a pressure difference between two points, and
  2. a continuous flow path or opening connecting the points.

If ductwork is not properly sealed, then your home or building does NOT have a continuous flow path connecting the points.



How Duct Sealing Improves Airflow

The Aeroseal duct sealing process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, then to each other until the leak is completely sealed. Sealed ductwork ensures conditioned air from the heating, ventilation, and air conditioning (HVAC) equipment actually reaches the desired rooms/spaces in a home or building instead of leaking out into unconditioned spaces like crawl spaces, attics, unfinished basements, and wall cavities.

Are you a homeowner? Duct sealing can improve the airflow in your home and help you feel more comfortable.

Are you a facility manager or business owner? Duct sealing can ensure the HVAC systems in your facilities performs as intended.
