Coolness is actually a lack of energy whereas heat is a concentration of energy. Entropy (the eventual breakdown of matter ie why icecream melts and coffee gets cold) to cool something requires that you displace the energy in something whereas heating something just requires adding to it. I suppose it’s easier to add energy than to displace it.
Hope this helps!
