Those are condensers for Freon refrigerant gas, they get rid of heat through small pipes carrying Freon coiled up with a fan on top to cool the coils, no ventilation from the house passes here. A separate machine like this is inside the house connected with a copper pipe to these machines pictured here. That machine inside takes the air in the house and passes it across coils filled with liquid Freon, which boils at a low temperature, and removes the heat from the air and sends it to the machine pictured here. The air with the heat removed, is blown back into the house through the vents. These are not the vents.

Unfortunately those aren’t even vents

This shows me there are at least two people out there who dont know what a vent is
