1) Do window A/C units, when set on the fan only setting, blow fresh air
in from the outside, like a regular box window fan, or recirculate air
from
the inside?


The air comes from the inside. It is pulled through the filter then
the evaporator and blown out the vents above. Some units have a
selector you can turn that will open a small door to let fresh air in
to the stream or to blow stale air out but this would only be a
fraction of the air.


2) Same question, but with the A/C turned on. Does the air come from the
outside or inside?



It works the same way. Doesn't matter if the compressor is running or
stoped.


Thanks Steve and to everyone else who answered! This explains why I am
getting warm air then with the fan-only setting. I had to run the A/C even
when it was cold outside, since the heat inside always runs inside the
house, making the temperature 76-77 degrees F. inside at all times! The
thermostat was fine, but something was wrong with the furnace so it almost
never stopped running, even though the thermostat was set at 58 degrees F.!
But my landlord finally called a furnace tech after a few weeks, at my
insistence, so hopefully this won't go on too long!
