Why do my lights flicker?

Occasional flicker when a big appliance starts (AC, dryer) is usually normal — a brief voltage dip. Lights that flicker constantly, in one room, or across the whole house are a connection problem until proven otherwise: a loose wire, a failing breaker, or a deteriorating service connection. Whole-house flicker is the one to take seriously — a loose service connection can arc and overheat.
