      Air conditioners are Heatpumps without a valve to reverse the direction of cooling/heating. If you flip an air conditioner around, it will produce heat at about 3 to 4x greater efficiency compared to an electric resistance heater.

        Most modern ACs have heating available as a function, so no need to flip it.

          Oddly, I’ve never seen a reversible window AC in my area. Checking my local stores, they’re definitely a bit more expensive than the non-heating models (cheapest I could find was $489), which might explain it.
