Electrical systems rarely fail without warning. The signs are usually subtle for months before anything dramatic happens — a flicker here, a warm outlet there, an oddly tripping breaker. Here's the short list of what to take seriously.
Take any of these seriously
- 01Burning, fishy, or plastic smell near outlets, switches, or the panel
- 02Outlets or switch plates that feel warm to the touch
- 03Lights that flicker, dim, or pulse when other appliances cycle on
- 04Breakers that trip repeatedly on the same circuit
- 05Two-prong (ungrounded) outlets throughout the house
- 06Discolored or scorched outlets and switch plates
- 07A buzzing or sizzling sound from outlets, switches, or the panel
- 08Mild shocks from appliances, faucets, or light switches
- 09Lights or outlets that work intermittently
- 010Visible cloth-insulated wiring, knob-and-tube, or aluminum branch wire
What's normal vs. what's not
- —Brief light dim when the AC compressor kicks on — usually normal on a 100A panel
- —Persistent dim or flicker every time the fridge or dryer cycles — not normal, get checked
- —One occasional breaker trip during a thunderstorm — normal
- —Same breaker tripping weekly — circuit is overloaded or there's a fault
- —Slight warmth at a dimmer switch — normal (LEDs help)
- —Outlet too hot to keep your finger on — not normal
What an inspection involves
A thorough residential electrical inspection in San Diego takes 60 to 90 minutes. The electrician opens the panel, samples a representative number of outlets and switches, tests grounding and GFCI/AFCI protection, identifies the wiring type behind the walls (knob-and-tube, cloth, aluminum, modern Romex), and writes up a prioritized punch list.
When to upgrade vs. just repair
Single failed outlet? Replace it. Repeated failures across multiple circuits, or any sign of knob-and-tube, aluminum branch wiring, or Zinsco/FPE panel? It's time to think about a partial or full rewire and a panel upgrade. We do free, no-pressure inspections in San Diego and surrounding cities.
Quick answers, straight up.
Why do my lights flicker when the AC turns on?
+
A brief dim when a large motor (AC compressor, well pump, garage door) starts is normal. A pronounced flicker every time, or flicker that lingers, usually means a loose neutral connection at the panel, the meter, or a major junction — call an electrician.
What does a burning smell near an outlet mean?
+
Almost always overheated insulation from a loose connection or overloaded circuit. Kill the breaker for that circuit immediately and call a licensed electrician the same day — this is the most reliable warning sign of an active fire risk.
Are two-prong outlets safe?
+
They're legal if they were original to the home, but they offer no ground path for modern electronics or surge protection. The right fix depends on the wiring: in some cases a GFCI replacement is code-compliant; in others you need to pull a new grounded circuit.
How often should I have my home's electrical inspected?
+
Every 5 years for newer homes, every 3 years for homes 30+ years old, and immediately before buying or selling. Insurance carriers increasingly request a recent inspection for renewals on older homes.
