What is the purpose of duct sealing in an HVAC system?

The primary purpose of duct sealing in an HVAC system is to prevent air leaks. When ducts are properly sealed, they ensure that the conditioned air travels efficiently throughout the home without escaping into unconditioned spaces. This can lead to improved energy efficiency, as well-sealed ducts minimize the amount of heated or cooled air that is lost during distribution.

Effective duct sealing can also positively impact the overall performance of the HVAC system, which can lead to consistent temperatures in different areas of the home and reduce the strain on the heating and cooling equipment. So, by preventing air leaks, duct sealing contributes significantly to energy savings and enhances comfort levels within the living space.

While duct sealing may have secondary benefits that can influence air quality and possibly reduce noise, the fundamental role it serves is ensuring air does not escape or enter the ductwork unexpectedly, which can compromise system efficiency and increase energy costs.
