Electrical Troubleshooting & Service Calls — Fairfax, Vienna & Northern Virginia

Note when the symptom started, which rooms or equipment are affected, what was operating at the time, whether a breaker tripped, and any recent storm, water, renovation, appliance, or utility event. Photos or prior repair records can also help.

That cannot be promised before diagnosis. Completion depends on the fault, safe access, required materials, panel or equipment condition, permit needs, utility involvement, and whether opening or restoration work is required.

Possible causes include overload, a short circuit, a ground fault, damaged wiring, a failing device, incompatible equipment, or a breaker problem. Repeatedly resetting it without finding the cause can be unsafe.

Thermal imaging can show surface temperature patterns under the conditions present during the visit, but it does not see through walls and cannot prove the condition of concealed wiring. It is one possible diagnostic input, not a complete diagnosis by itself.

Diagnostic testing itself may not require one, while the resulting repair could. Requirements depend on the address and defined work, so AJ Long Electric confirms the permit and inspection path after the cause and repair scope are known.

Keep people away from the affected area. If it is safe to do so, stop using the equipment or circuit and call for guidance. Smoke, fire, downed lines, or immediate danger require emergency services and utility instructions as appropriate.
