Improving Energy Efficiency of Duct Systems

COURSE NO: M01-006
Improving Energy Efficiency of Duct Systems
Course Highlights

This online engineering PDH course describes some of the basics about residential ductwork, supply and return systems. This course addresses both the energy and health impacts of residential duct installations.  Retrofitting of existing residential duct systems is possible under the guidance of a professional; however, it is best to properly install the ductwork in new construction so that the system can operate at maximum efficiency from the beginning of the installation.


The duct system, used in air heating and air cooling your home, is a collection of tubes that distributes the heated or cooled air to the various rooms. This system can make a big difference in both the cost and the effectiveness of heating and cooling the home. The duct system can have an important effect on health of the occupants through the distribution of indoor air pollution.


This 1 PDH online course is applicable to mechanical engineers who design ductwork systems for commercial facilities and residential facilities and wish to improve on the energy efficiency of this air transporting conduit of the system.
