I've heard from several customers of mine that they have been offered this, and now seen a friend post on Facebook. They are offering to "service and clean your electrical panel" with the promise of "lowering your utility bills". They have even claimed that old breakers will somehow use more power than new ones. From everything I've been taught this is complete BS. Does anyone here have any scientific reason that these claims are anything more than just a way to scare customers into unnecessary work?
