What is the typical thickness range for residential HVAC ductwork?

In residential HVAC ductwork, the typical thickness range is measured using gauge, which indicates the thickness of the sheet metal used. The choice identifying a range of 26 to 22 gauge is correct because this is the standard thickness for residential duct systems.

Ducts that are too thick can be unnecessarily heavy and cost more to fabricate and install, while those that are too thin may not withstand the pressure and could lead to leaks or structural failure. The 26 to 22 gauge range provides a balance that ensures the ductwork is robust enough to handle airflow while remaining manageable for installation and economically feasible.

This standard is widely accepted in the industry for residential applications due to both performance and efficiency considerations.
