I had the exact same thing catch my attention yesterday too. I was gonna post it but couldn't think of a good way to describe it.
AC was on, cause it hit 90 already!, sounded as if an air pump was filling something up (ramping up) for a few seconds, then it would stop for a few. Was very consistent.
