Attic Ductwork Layout

To promote balanced air circulation through the supply ducts home and return ducts the ductwork should be simple in layout accurately sized sealed insulated in unconditioned spaces and installed in the right places.

Attic ductwork layout.

This involves return air unconditioned coming into the heating cooling system. The purpose of residential ductwork design is to properly distribute the airflow produced by your heating cooling system to your house. When hvac ducts are installed in a vented attic in a dry climate bury the ducts in attic insulation to protect them from temperature extremes in the unconditioned attic space. Route ducts between joists in a basement if possible or over them if necessary.

Install ductwork so that it is in direct contact with i e laying on the ceiling and or truss lower cords. When the location of hvac equipment and duct system and not optimized in the planning phase the equipment may end up far away from the space to be cooled. Place ducts on top of joists in a ceiling or attic. That may require long runs of ductwork that make it hard for your hvac system to move conditioned air to certain areas within the space.

Runs that are too long. Make the layout as symmetrical as possible with branch ducts spaced evenly along the. Situate the air handler close to the center of the layout to minimize the length of ductwork spans. Avoid any hot elements such as water heaters heater or stove.

Then by heating cooling that air delivering the newly conditioned air to.
