Heat is a form of energy right? So if we take away the energy from the Air we have concentrated some heat elswhere which we should be able to harvest? So i ask myself why are Air conditioners not a source of energy?

There is at least one device that uses the heat that is pumped out of your house as an energy source. A “heat pump water heater” extracts heat energy from your home and put it into your water.
A heat pump is most efficient when the temperature of the exhausted heat is only slightly above ambient. The higher the exhaust temperature, the more energy you needlessly added to the refrigerant.
For the heat pump water heater, “ambient” is the desired temperature of the hot water, not the outside air. It would be more efficient for the water heater to draw air from the hot outdoors, but by operating indoors, it also reduces the load on the air conditioning.
