Fucken hell. On top of all the other stuff I have to worry about, now I have to worry about the capacitors in my AC? I am already stressed out about harmonic distortion and power factors.
But thanks anyway for the heads-up.I have had ongoing issues with my bedroom AC and maybe a wonky capacitor is the answer.
Don't stress out too much... add in line conditioners between the outlet and any valuable electronics which would be sensitive to it. There's no real "fixing" the problem unless you're going to rewire your entire neighborhood, including the power station... but you can mitigate it's impact on your personal electronics with high quality conditioners.
Experience source: Common problem with pro audio rigs running on generators or on warehouse power, which we often used at event when I was a younger man having much more fun. A $300 conditioner saved us from having to repair/replace a $10,000 amp and control board after each gig.
That said, not a lot of things are sensitive enough to be bothered about it... stuff with capacitors or logic boards but not already going through a transformer (like the AC, a Fridge, TV, etc) before reaching said circuits... as the transformers should even things out before they hit the device in question.
