Ductwork installation refers to the process of installing the network of tubes, ducts, and vents that are used to distribute conditioned air from an HVAC (heating, ventilation, and air conditioning) system to different rooms in a building. Proper ductwork installation is essential for the efficient and effective operation of HVAC systems, as well as for indoor air quality and comfort.

The following are some key steps in the ductwork installation process:

1. Design and planning: Determining the size, layout, and location of ducts based on the heating and cooling requirements of the building.
2. Fabrication: Manufacturing or purchasing pre-made ducts to the specified design.
3. Installation: Securing ducts in place using metal straps, clamps, or adhesive. Sealing all joints and connections with mastic or duct tape to prevent air leaks.
4. Insulation: Wrapping ducts with insulation to reduce heat loss or gain and to reduce noise.
5. Testing: Testing the system for proper air flow and leaks using a duct tester or anemometer.
