The AC is a whole house unit. I know the breaker that a tried turning it off. It still didn't make a difference. I was wondering that even though it is off, can it still cause noise? Any suggestions for a good noise filter?
Since your Air Conditioning unit is a whole house unit, then I doubt that it is causing the problem. If it is a noise problem, then do as I sujested earlier, start turning off breakers until the problem disapears, then turn the breaker back on and identify the device that is causing the problem, this could be a TV, DVR, UPS, Computer, etc. Once you identfy the problem, you can get a Noise filter from such places as Smarthome.com
