It is a common belief among HVAC contractors that uninsulated ducts in a conditioned space do not contribute to a loss in energy. However, there are several problems that may arise such as:
- Duct Condensation
 - Hot and cold rooms
 - Uneven temperatures
 - Excessive run time of multistage and variable capacity equipment
 - Unexpected Btu Loss through ducts
 
This article from ACHR explains how these problems can arise, how to identify them, and why insulation can be a viable solution to ensuring system performance when controlling temperature loss. Read now.
