Air ducts provide a pathway for air to flow through the heating, ventilation and air conditioning (HVAC) system and distribute conditioned air throughout the building. Clean air must flow over evaporator coils as part of the heat exchange process. If air ducts are not properly designed, installed or maintained, any energy efficiency gained by high-performance equipment is lost through poorly functioning ducts. Properly designed ducts help maintain consistent indoor temperatures while delivering air quietly.

Ductwork Design and HVAC Performance

Ductwork efficiency may be as low as 60 percent because of leaks or poor design. An efficient duct system can save up to $200 each year in heating and cooling costs. Properly sized ducts complement air conditioner performance. Efficient ductwork can reduce the size of heating and cooling units, which helps homeowners and businesses save money on equipment costs.

Leaking ducts let pollutants enter the HVAC system. Contaminants not only settle on coils, which affects air conditioner performance, but are blown into the living space, compromising indoor air quality. Poorly designed ducts can affect interior air pressure, causing backdrafts that pull dangerous gasses into the living space.

Contractor Standards for Duct Design and Installation

When designing a new system, an HVAC contractor should use the Air Conditioning Contractors of America’s Manual D, the industry standard for ductwork planning, design and installation. An experienced contractor will recommend materials such as sheet metal, fiberglass or flexible, nonmetal products that best suit your needs and budget. Sizing and placement of registers, plenums, grilles and diffusers are also part of the design and contribute to efficiency.
