HVAC General Info
The HVAC, or Heating Ventilating and Air Conditioning Assembly, is the unit located under a car’s dashboard that is responsible for controlling the flow of air into the cabin. The HVAC is composed of multiple injection molded polypropylene cases that are fastened together. An array of dampers and motors inside the unit allow incoming or recirculated air to be directed in many ways. It serves to provide hot air to the windshield for defrosting as well as the cabin area for heating. The HVAC unit can also provide cooling to these same locations.
