Regardless of whether it technically qualifies as “Chessed,” you did a favor for a friend. It should be obvious that Hashem expects us to act in such a way, even if not specifically mandated to do so under the rubric of Chessed (much like inviting friends for Shabbos Seudos is not technically Hachnasas Orchim). The only caveat (in my opinion) is to make sure your friend is not taking advantage of you, which a true friend would never do.
I would venture to say that the idea that “if it isn’t technically the Mitzvah of Chessed, I’m not doing it,” is described by the Gemara as ?????? ?????? ?? ??? ????, which is given as the reason for ????? ??? ?????.
