why is it easier to heat things up, than it is to cool them down?

It’s not, it just depends on the relative energy levels and how efficient the materials are at retaining or transmitting thermal energy.
Take two objects, both with the same mass and thermal conductivity (assume a closed system and these are the only two objects in it). One is 0C and the other is 100C. Place them together (or don’t it doesn’t really matter where they are in this scenario). Over time the one that started at 0C will be heated to 50C. At the same time, the one that started at 100C will cool to 50C. They both heat up/cool down the same. It’s not a matter of heating up or cooling down, its just movement of energy between relative levels.
