Default Does cooling require more BTU/hr than heating to maintain same temp difference?

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?


True, but the LOSSES (efficiency) of causing that are
grossly different. Your analogy is sound, but it ignores
the losses involved in makng that change occur, which is
what the OP was asking about. I'm afraid getting into a
technical debate, especially one with the lossless descrip
you're trying to use would be futile and take way too much
ether and time. Keep reading; it's there.
