My neighbor has a short-cycling outdoor A/C unit (Texas) which means it’s turning on and off much faster and more often than it should. This will eventually kill the motor and often leads to needing a new unit. Their unit is quite old and has done this three times in two years now, twice fixed with apparently something minor (don’t know). I did speak to them the first time just to let them know, since I’ve had it happen to me before and it’s expensive. They were total jerks and told me it’s fine and I can pay for it if it bothers me that much. Cussed under their breath as I walked away. The motor died 2 months later (told ya). ANYWAY its back and it’s right by my bedroom, about 10 feet from my head. It turns on and off every 3-4 minutes now, but in a month it will be about every minute, and in two months it will be every 4-6 seconds. I know because this has ruined my sleep/sanity three times now, for that long each of the first two times. The sound is quite loud since the motor is taxed and it wakes me up. I can feel the kick of it turning on through the walls and ground. It also makes my electricity flicker when it turns on - the city came out and checked for me and I lose half my wattage, but not full power so they wouldn’t do anything. I moved to the spare room on the other side of the house last year but darn it this is my house and I want my bedroom. These neighbors won’t go away and are not reasonable so I’m looking for advice. Things I’ve tried besides being a friendly neighbor? Last year I bought sound dampening blankets - like for generators, ceiling panels, plywood, foam egg crate things, and some gym floor mats and made a wacky wall against my wooden fence by their unit. It all got rained on and anything not wood or plastic ended up in the mud and super trashed - took forever to sift out of the dirt. I built a giant sized baffle box like I would for a camping generator - it seemed to shoot the sound up under their roof overhang and I didn’t get any relief. I’ve looked into acoustic panels ($$$ eek), or getting insulation sprayed into my walls (meeeeh..), or a remote controlled generator so I can just drown out their sound with a more consistent sound and at least sleep (I still like this one but kind of a jerk move), or even jerkier some kind of “slap on the wrist bell” where when you make a sound that produces X amount of decibels in my bedroom this device will automatically respond with a sound that will produce the same amount of decibels in your home (can’t flicker their lights though). Found some funny renditions online. I’m not going to be a jerk so.. what can I build or construct, and with what materials, that can help me drown these people out? There are city rules on fence height, but I finally have no HOA!
