Most electrical repair calls in Moline and the river towns are not about a part. They are about finding which part. A dead run of outlets in a Rock Island foursquare may trace to a backstabbed receptacle three rooms away, a tripped GFCI in the garage nobody knew existed, or a splice in a ceiling box that finally let go. The electrician who takes your call diagnoses before he replaces anything, and the quote names the actual cause.
Breakers that keep tripping
A breaker that trips once a winter when the space heater and the microwave run together is an overload, and the honest answer is a dedicated circuit, not a bigger breaker. One that trips instantly when a particular appliance starts is a short or a failing motor. One that trips for no pattern at all, warm to the touch, is often the breaker itself wearing out, which happens to forty-year-old breakers in East Moline panels more than people expect. A GFCI or AFCI breaker that trips on a circuit with nothing plugged in usually means a neutral is touching ground somewhere in a box, and finding that box is the job. Each of those is a different repair with a different price, and the electrician tells you which one you have before quoting it.
Flickering, dimming, and the storm that came before
Lights that dim when the air conditioner starts are normal on a small service and a sign of a loose neutral on a large one; a loose neutral is the one symptom on this page that should not wait until the weekend, because it sends 240 volts through 120-volt appliances. Flickering that began after the last MidAmerican outage points at a damaged main breaker or a corroded meter-base lug, and after the 2020 derecho a good many Moline houses had exactly that. Whole-house flicker with no appliance running is often on the utility side of the meter, in which case the electrician says so and you call the utility instead of paying for a visit that changes nothing.
Dead outlets, warm plates, and buzzing
A single dead outlet in a 1950s Silvis ranch is usually a worn receptacle or a backstab connection that lost its grip. A whole room dead is a tripped GFCI upstream, a failed breaker, or a broken splice. A switch plate that is warm, a receptacle with a brown ring, or a buzz from inside a wall are the calls that get moved to the front of the day, because each one is heat where heat does not belong. Turn the breaker off, leave it off, and phone rather than use the form.
What stays with the electrician and what does not
Everything from the meter base into the house is the electrician's work: breakers, wiring, boxes, devices, fixtures, the disconnect for the air conditioner. The condenser itself and the furnace are a mechanical contractor's equipment. The gas valve on a furnace or water heater is a licensed plumber's, because Illinois licenses plumbing at the state level. A doorbell camera is yours to install; a monitored alarm panel is licensed alarm-contractor work. When a repair crosses one of those lines the quote says which.
