Why do my lights dim when the AC turns on?
Your AC compressor draws a large surge of current at startup, which can momentarily dim lights on the same circuit or even the whole panel. A brief dim is normal. If lights dim significantly or stay dim, your panel may be undersized or the AC circuit may need a dedicated line. A hard-start kit ($150–$300 installed) on the AC can also reduce the startup surge.
Are flickering lights a fire hazard?
They can be. Flickering from loose wiring connections is a fire hazard because arcing generates heat. If accompanied by warm outlets, buzzing sounds, or burning smells, turn off the circuit and call an electrician immediately. A loose connection at a single fixture is lower risk but should still be repaired.
