"how come you measure both a heater's ability to heat and an air conditioner's ability to cool in BTUs?"
Because they are both heat transfer devices and you are measuring the British THERMAL Units, the HEAT, they produce.
Your air conditioner does not produce cold, it produces HEAT on the exhaust side. Or more correctly, it transfers HEAT from one side to the other. When it moves the heat outside, you call it an air conditioner. When you reverse the heat flow...that's also called "reverse cycle" heating, and yes, there are systems that work in both directions--making the "inside" hot or cold.
Still comes down to how much HEAT they move or produce, so it is still British THERMAL units.
It sure would make good reality TV if little gray men came down one night and stole all the air conditioners south of the Mason-Dixon Line. Somebody buy me seats on THAT 50-yard line! Or better yet, not on that line...just someplace way cooler north of that.
Cold good! Heat bad! Humid heat, worse! Leave it to the gators and bugs!
