Stupid question about A/C :)?

Question

when you put a window or central AC on "fan" mode does it pull in air from outside or recirculate the inside air? thanks!

Answer 1

A central unit ONLY uses inside air. Some window units have provision for outside air and some don't.

Answer 2

No it is true your question is valid.

if it is a window A/C i think it does a little of both.

i want to see what others have to say also , perhaps, somebody that actualy works in air/cond. would be

good.

Answer 3

The "fan" mode on an air conditioning unit---either window or central---will recirculate air.

The "auto" mode is the one you should  use when you wish to have your air cooled.

Answer 4

It's really not a stupid question..because I'm going to watch to see the answer to it too! lol

Answer 5

inside air

Answer 6

Most window units only pull it from outside. The ones that recirculate inside air are rare.
