Sorry but that is not true.
15 years ago the neutral failed at the transformer and our aAC was
cycling
up dan down smoething wierd. My low voltage alarm tripped, and woke us
up. I killed the breakers and called the utility.

The other 3 homes had damge to their refridgerator and heat pump
compressors. Motors don't like AC that runs from near 0 to well over
normal.
