Everyone seems to be making the same mistake here. As you say:

> Generally speaking, an A/C uses approx. 1 unit of electricity for every 3 units of cooling that it produces since it uses heat transfer rather than heat generation

You know you can use a heatpump to heat a space as well right? Then you get to move 3 units of heat into the space, plus you also get to use that extra unit energy used to power the heatpump, because the heatpump turns the unit of energy into waste heat! (After all energy can’t be destroyed, so it has to go somewhere).
