In Hollis, New Hampshire, this homeowner needed improved airflow distribution throughout the home. Accutemp Engineering designed and installed a full duct layout on a 4-ton system to deliver balanced, consistent comfort to every room.

We began by installing 2 main trunk runs of 12×8, carefully routing each line to support proper airflow across the system. Our team then added 3 supply outlets at 7″ on Trunk 1 and 2 supply outlets at 7″ on Trunk 2, ensuring even distribution throughout the space. We also reconnected a 12″ round R8 flex duct to the main return box, supporting efficient air return back to the system.

After ductwork was complete, we finished the installation with 10×4 ceiling grilles and stock white ceiling grille covers for a clean, uniform appearance. This project reflects Accutemp’s experience with custom duct design and air distribution systems across Southern New Hampshire and Massachusetts.
