My SO said the above statement and gave me an explanation “Cold is the absence of heat or energy”, it does make sense however in my head it is like saying (in very simplistic terms) “the countryside is the absence of a city” and that is just a ridiculous statement.

if you want to heat something up, you add heat
if you want to cool something, you don’t add cold, you remove heat
in case the retort is “but my air conditioner adds cold air to the room & that cools it down”
no, it takes in air, removes heat from it & places that air back into the room.
that’s why window units are window units, the heat is spit out the back to the outside.
also why central air units are outside the house but water heaters can be inside.
(central AC is spewing the removed heat, water heater is not putting out removed “cold” it’s just adding heat to the water inside it)
