Run a dedicated line to your electronics and make sure the AC is on the other side of the panel from the dedicated line.
If you can't run a dedicated line, then have an electrician move your audio line to the other side of the panel, isolating it from the AC line.
Perhaps if an old home, you may need to update the panel or you could add on a poney panel and isolate some lines.
Make sure the wiring in the walls meets code,they can get pretty hot if they aren't the proper guage and AC is drawing a lot of juice.
Old homes have been known to lack the proper guage wiring for all of todays conveniences.
