I have wondered something very similar to this myself. I think (at least in most cases) it is easier, on evolutionary timescales, to adapt to local climate conditions, rather than develop the machinery (and spend the metabolic energy) fighting against those conditions.
As far as I know, there are also no organisms that directly extract metabolic energy from wind, wave, tidal, other mechanical motion. Chemosynthesis based on thermal gradients AFAIK only happens in bacteria near hydrothermal vents. I assume any biological heat pumps that could exist would need to be macroscopic to be useful, but really insulation, coloring, and evaporation are just simpler.
