They also assemble and install the ductwork that delivers the cooled or heated air from the HVAC system to buildings. This includes cutting sheet metal and attaching it to the ducts, mounting the ductwork to the building and connecting the ductwork to registers that control individual spaces.

Some technicians specialize in specific types of units, such as furnaces or air conditioners. They can offer advice about which models of heaters and ACs are best for homeowners, how to keep their units running efficiently and when it makes more financial sense to replace them with newer, better energy-efficient units.

When working on a project, they may also be required to comply with government regulations and local HVAC codes concerning the safe handling, conservation, recycling and disposal of refrigerants and other fluids used in heating and cooling systems. They also need to understand the physics involved in the operation of HVAC systems, and explain them in a way that homeowners can easily comprehend.
