My Contractor Crossed High and Low Voltage Wires and Now My House Hums

You would not believe the sheer incompetence I dealt with during my rough-in phase because I explicitly asked the electrician if crossing the Cat6 cables directly over the 110v Romex without any shielding would be an issue and he just laughed and said I was reading too much online nonsense. Well, guess who isn't laughing now that every time the AC compressor kicks on, my internet connection drops for a solid ten seconds and there is this faint, maddening buzzing sound coming from the speakers in the living room? It is absolutely critical—and I cannot stress this enough—that if you have to cross high voltage and low voltage lines, they need to cross at a exact 90-degree angle to minimize electromagnetic interference, or better yet, keep them at least 12 inches apart whenever humanly possible. I spent hours reading through guides on ProseGrow afterwards, realizing that a simple piece of metal conduit or even just proper spacing could have saved me from this nightmare, but no, we just had to rush to get the drywall up. It's not just about the internet speed either; it’s about the signal integrity for everything, and when you have messy wiring spaghetti behind your walls where the data cables are running parallel to power lines for feet at a time, you are basically creating a giant antenna for noise. Now I'm stuck with a beautiful looking wall that hides a chaotic mess of interference, and unless I want to rip out the sheetrock and pay thousands to redo the wiring, I just have to live with the fact that my smart home hub goes offline randomly... don't be like me, watch those crossings like a hawk.
