Do airconditioners take air from inside or out?
I know it pulls air in from indoors, but does it also bring in air from outside?
Thanks!

The best systems being developed draw outside air, which passes through a HEPA filter and mixes it with the recycled air. The only way to capitalize on its benefits is to ensure your house is sealed from leaks. Various companies offer this. If you are getting a lot of dust in your house it is most likely a leaky duct that is drawing air from dead space (i.e. crawlspace, attic, outside). If your system was not designed in mind then it is the standard setup and all you get is inside recycled air.
From the inside. Every system you see will have a ‘return’ vent. Many times, these are vents on the floor that are bigger than a normal wall vent.
only takes outside air if you open the outside door on them, usually they just recycle the air in the room and the outside takes outside air and blows it across the condensor outside,,
Many window type air conditioners can be set to put in some outside air. These may be adjustable. The type that are fixed to an internal wall with the compressor and other works outside on the ground cannot take in external air as there is no passage for air. Some models may have provision for external air but this would need a hole in the wall or some other arrangement. To a large extent all of this depends on how much you are willing to pay.
