What Makes for Good Ductwork Design? You’ll Need to Know for Your New Home or Redo

Whether you are building a new home, or are undertaking substantial renovation, implementing good ductwork design can save you money and improve the efficiency of your home heating and cooling systems. Your household’s ductwork design can make or break your home comfort system, so this is the time to get it right.

Good ductwork design, professional installation and regular expert maintenance are necessary for your heating and coWhat Makes for Good Ductwork Design? You'll Need to Know for Your New Home or Redooling system to operate at its peak energy efficiency. The initial duct design should account for the layout and size of the house, in addition to other design concerns. Ideally, this is done before the house is built, but because many building contractors designed ductwork without consulting with HVAC-specific experts, many homeowners have poorly functioning ductwork that leaks, doesn’t deliver air efficiently, and/or creates hot and cold spots, making a redesign necessary.

When professionals design ductwork, the main goal is to minimize energy loss. Air ducts should transfer conditioned air – the air your central system has filtered, heated and cooled – from your central HVAC equipment to your living spaces as quickly and directly as possible. To do so, good ductwork design should include efficient configuration and balanced airflow.

  • Configuration. You want your sections of ductwork to be short enough to allow for good airflow control and stability, without being impeded by your home’s layout. The two most popular ductwork configurations are the trunk-and-branch and radial systems. In the trunk-and-branch system, one main duct connects to the air handler. Smaller air duct segments branch off from this “trunk” to provide conditioned air to home living spaces. In the radial system, many short ductwork sections are connected to the air handler.
  • Balancing Airflow. Good ductwork design should ensure that supply and return ducts are properly placed throughout the home to facilitate good airflow. Supply ducts release conditioned air flow, and return ducts are where stale air is guided back in and pushed on to the central equipment to be re-conditioned.
