Good grief, there are certainly a lot of "logic"
answers here, most with some but not much merit.
Simply stated, it takes a LOT more energy to drop the
temp a degree than to raise the temp a degree, because
of the methodologies. The technology for increasing
temperature is simply much more efficient that that for
lowering the temperature.

Explain please.

If you have a mass and remove 5,000 Btu or add 5,000 Btu, it is still the
same amount of energy it is still the same mass. Since Btu is really an
expression of Btu PER HOUR, the same amount of energy is being moved in the
same time period.

Take the window AC unit and mount it backwards so it exhausts from the
condensing coil the heat into the room. Would the effect of running it
raise the temperature more or less than a heater that gives of 5,000 Btu of
heat? If two rooms were the same temperature and one had the heater, the
other h ad the AC (assuming the outside air is at the temperature used to
get the 5k rating), which room would be heated more?
