i know the air conditioner pulls air from inside the room and cools it, then returns the cool air to the room...but does it also pull any air from outside?

"As a very generalisation, window units and 'through the wall' units do not draw air from outside unless they have a specific control for drawing in outside air. Any outside air leaking in, or being purposely let in, will lower the efficiency of the system.
Very few homes are anywhere near 'airtight' closing the windows and doors will keep out some odours but not all. Doors are particularly difficult to get anywhere near airtight. Then look at all the other openings you may have, dryer vents, exhaust vents from bathrooms and laundries, range hoods exhausting to outside, all these allow air and odours in."
No, air conditioners do not bring in fresh air from the outside. The air that comes from the outside is contained with harmful elements. These elements can cause allergies and asthma symptoms. But, before the air enters a house, it goes through an air filter. Air filters are used to trap pollutants to make the air healthy to breathe in.
A common misconception is that window air conditioners pull in outside air to cool a room. In reality, most window AC units recirculate indoor air rather than drawing in fresh air from outside. However, some models include a vent control feature that allows limited outside air intake, which can help improve ventilation.
How Window AC Units Work
Window air conditioners work by drawing warm air from inside the room, passing it over cooling coils, and then blowing the cooled air back into the space. The hot air is expelled outside through the rear of the unit. This closed-loop system ensures efficient cooling without directly relying on outside air.
