My system here is still running Ubuntu 20.04 so almost 4 years without
an upgrade or reinstall, and I use a few extra snaps such as ccls,
Emacs, and valgrind as well as the system snaps.  I refresh regularly.

My /var/snap is tiny:

  ~$ snap list | wc -l
  18

  ~$ sudo du -sh /var/snap
  25M     /var/snap

Maybe next time you notice it to be so large you should investigate
further first (for example, find out WHICH snap is using all the space
via "du -sh /var/snap/*" or similar) before tossing everything.
