What does the Vent/Pull switch do? - Kenmore 75085 Air Conditioner

Vent allows fresh/outside air to be mixed in with the room air when you desire some fresh air instead of just recirculated room air only.

It is best to allow some fresh air when the temps aren't all that high, or when it's not too humid, or when you have a smoker in the room, otherwise the same old (stale) air keeps getting passed through the A/C.

If you keep the vent closed, your A/C will usually keep the room cooler, as it keep cooling the existing room air and can extract more moisture from that air, which is especially beneficial when it is extremely humid outside. In the most basic description, A/C is really just a dehumidifier with a cooling unit built in, which extracts moisture from the existing air and then chills it to make us people more comfortable.
