One lamp flickering is a $2 problem. Every light in the house dimming when the AC compressor kicks on can be a utility problem — or the early signature of a loose service connection, which is the kind of thing you want found early. The diagnosis ladder goes bulb → fixture → circuit → house, and each rung takes about two minutes.

Scan It FreeLEDs flicker from age, cheap drivers, or loose contact. Try the suspect bulb in another fixture — if the flicker follows the bulb, done for $4.
Old dimmers chop power in a way cheap LEDs hate. Fix: 'dimmable' rated bulbs AND an LED-compatible (trailing-edge) dimmer, ~$25. This combination is behind a massive share of modern flickering.
Breaker off. Drop the fixture, check the wire nuts snug, look for the push-in connector or scorched insulation. Loose neutrals at the fixture read as random flicker.
Flicker across a circuit usually traces to a loose backstabbed outlet or switch daisy-chaining power onward (see our dead outlet guide — same fix, move to screw terminals).
Brief dim when the AC/dryer starts is normal-ish (motor inrush). But regular deep dips, flicker without appliance triggers, or brightness that surges up deserve attention at the service level.
Loose neutral at the weatherhead/meter is the dangerous one — symptoms include some outlets reading weird voltages and lights brightening while others dim. Utility checks their side free. Scan your symptoms in SpotFix AI to build the timeline before the visit; it makes the diagnosis faster.
