Is HVAC mechanical or electrical?

HVAC systems are a combination of both mechanical and electrical components. The mechanical components include the ductwork, fans, and other components that move air through the system. The electrical components include the thermostat, motors, and other components that control the system. Both mechanical and electrical components are necessary for a functioning HVAC system. The mechanical components are responsible for moving air through the system, while the electrical components are responsible for controlling the system.
