It uses the same amount of energy to create cold as it does to create heat.
Well it's about temperature differences, those are larger in winter I guess. On the other hand there is a lot more radiative heat load in summer...
There's a "sweet spot" for temperatures, so if a compressor and heating agent works well in summer, it won't work well in winter.
Heart pumps don't create heat, they move it.
