Not every HVAC system includes a fresh air intake. Some systems rely solely on recirculating indoor air, while others incorporate a fresh air intake to improve indoor air quality.
The fresh air intake would be the vent from the roof of the house that allows the system to breathe, unless the sewage lines are plugged

The purpose of an HVAC intake vent is to bring in fresh air from outside into the system. This fresh air is then heated or cooled before being circulated throughout the building. The intake vent helps maintain proper air circulation, temperature control, and air quality within the building, contributing to the overall functioning of the HVAC system.
The Chevy Cavalier does have a fresh air intake filter. The fresh air intake filter is located behind the passenger side kick plate.
Maintaining the furnace fresh air intake is important for ensuring proper functioning and efficiency of the heating system because it allows the furnace to receive the necessary oxygen for combustion. Without enough fresh air, the furnace may not burn fuel efficiently, leading to decreased performance and potential safety hazards. Regularly checking and cleaning the fresh air intake can help prevent issues and keep the heating system running smoothly.
The difference between a fresh air and a regular intake on a vehicle is the location of the inlet. Fresh air uses and inlet at the extreme front of the vehicle, while a regular intake can be anywhere and pull in heated air from the engine.
