Good performance of the HVAC systems depends on eliminating leaks in the plenum and ducting system and reducing friction within the ducts themselves. This 3-part video shows how to accomplish these goals, which also reduce attic air infiltration into the system.
Central HVAC equipment distributes the air through out the house by a system called “duct work.” When this system is properly designed, air distribution is even and a uniform temperature is maintained. Proper duct work design can allow for the correct sizing of systems, thus increasing savings.
