I was reading the post about a boiler which dimmed the lights in the house.
It intrigued me, because all of a sudden I have a similar problem.
My lights just started dimming a couple days ago, and I wondered what was
causing it. Now, you may think I'm cuckoo, but I figured it out while
sitting out on my deck at night. Every time my lights dim, it's because my
neighbors A/C kicks on. It never fails, I had my wife sit out there with
me, to make sure it's not my imagination. How is this possible? What steps
do I take to correct this?
