Will an air conditioner pull cold air from your house after all of the warm air is already pulled out of it? I was told it is impossible for an air conditioner to pull anything but warm heat.

If functioning normally, the AC should draw air from the outside (presumably same temp air at starting point as what is inside). As the AC unit runs, the warm air passes over freon cooled array of copper tubing from a fan which drops the temperature and delivers a cooler mass of forced air into a closed space (home, room, etc.) If the unit is run in colder weather the noticeable difference in temp will be between the ambient RT and what is outside.

AC unit should not pull cold air from your house unless the direction of the blowers were reversed- in effect creating a vacuum in your home as air was being drawn out. I think you may be thinking in terms of an add-on electric heat pump.

When the compressor is running, the AC is
blowing cold air and sucking warm air out.
When the compressor cuts off it is blowing air
but it is not cold and at the same time it is
sucking out the air that is in the house. However,
that does not occur for a long period cause
the thermostat causes the compressor to kick
in again.

That's correct -- once the air conditioner has pulled all the heat from a room/house, it will shut off until the temperature rises again. It is against the laws of thermodynamics for cold to go to hot -- only heat can travel to cold.

hi Nancy: 2 straightforward issues you are able to attempt is to change the filter out and sparkling the indoor and exterior coils. i've got considered this improve the performance of structures by 50%. to verify in case your helpful air unit is working right, turn the gadget on and take a sturdy thermometer (i exploit a cooking thermometer) and place it interior the return vent (the vent happening your furnace). supply it a jiffy, then write down the temperature. Then visit a grant sign in (one that ingredients air to the room) and place the thermometer there for type of 5 minutes. The air popping out could be sixteen-20 stages cooler than the air entering into. whether it particularly is 15 stages or much less OR 22 stages or extra, you have a concern which will would desire to be dealt with by a professional. in case you have a sturdy temperature drop, the gadget may well be undersized; you will prefer one "ton" of cooling means (12,000 Btu) in line with 900 squareft of floor area. (In KS, you are able to prefer 1T in line with seven-hundred ft2.) different than changing your gadget, you should upload a wall or window mount unit on the south side of your place. are you able to plant some poplar trees and different deciduous trees on the south side of your components? they gained't help this or next 3 hundred and sixty 5 days, yet after that...
