It's pretty easy to determine.
Listen to your system over a few weeks at 2AM or another time when electricity usage is low vs other times of high usage like 8PM on a weeknight. If there's a significant difference and you'd like your system to sound more like the low usage times all the time you get a quality power conditioner.
I live in a city; the difference was pretty dramatic.
