</p><h3 id="section---Systems">Systems</h3><p>Industrial and commercial HVAC-R systems include such components as air ducts, piping, vents and thermostats. Technicians are responsible for installing and maintaining these systems and ensuring that each part is functioning correctly. Refrigerators, freezers and air conditioners operate with liquid refrigerants to expel heat from indoor areas. Similarly, heating systems use oil, gas and electric components to generate heat, which is then distributed through air ducts and vents.
