Why do my lights flicker when my neighbors AC turns on? Any heavy current draw on one branch of the circuit will be seen as a voltage droop back up the line toward its source. As that droop passes the point where your mains connection joins in with the neighbor's mains your branch will see a corresponding droop in voltage.
Why do my lights flicker when my AC turns on?
This damage, such as discolored or charred wiring, is likely causing current loss to your lightbulb. In combination with the temporary voltage drop that occurs when your AC turns on, it could cause your lights to dim or flicker more significantly than is normal.

Why do the lights dim momentarily when the refrigerator motor comes on?
When a motor, any motor, starts up it requires about twice as much electricity to get started than it does to keep turning.
