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

Diagnostics and repairs cost $195 for the first 30 minutes, then $60 for each additional 15 minutes. Many common issues can be diagnosed and resolved within 30–60 minutes. Timing depends on the issue; more complex problems can take longer.

Tell us which rooms or equipment are affected, when it began, whether it is constant or intermittent, what was running, and any recent storm, water, renovation, or appliance event. Safe photos and prior records help. Do not recreate the fault, touch a hot device, or remove covers to collect information.

Many common issues can be diagnosed and resolved within 30–60 minutes, depending on the issue. 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.

If you suspect an electrical fire, evacuate and call 911 from a safe location. Do not wait for an electrician or approach electrical equipment to investigate. Keep away from wet equipment, exposed wiring, or damaged service parts. For downed lines, stay clear and contact emergency services and the utility.

A free estimate prices a defined installation or project. Troubleshooting is paid work to identify and, where possible, repair an existing fault. If testing is needed to establish the cause, choose troubleshooting rather than assuming the diagnostic work is part of a free estimate. We discuss any separate installation scope before proceeding.

Yes. A problem affecting one property can still involve the utility connection or service equipment. Neighboring lights being on does not prove the fault is inside your branch circuits. Check the serving utility's outage information from a safe location and describe whether the loss is whole-home or partial.

Share the pattern and any safely collected observations. An intermittent fault may not be present during the visit. Testing can narrow the possibilities, but an unobserved cause should not be represented as confirmed or repaired. We explain remaining uncertainty and reasonable next steps.

Not simply because it trips or loses power. The cause can be connected equipment, wiring, a protective device, or the supply. For example, a GFCI that will not reset may have no incoming power. Diagnosis helps avoid replacing a part while leaving the underlying problem.

Make safe access available to affected rooms and the closed electrical panel, secure pets, and have relevant equipment information ready. Do not move damaged wiring, open covers, or touch wet or overheated equipment. Tell us about access limits or equipment that cannot be interrupted.

No. Staff review the symptoms and contact you about the next step and availability. A request is not a confirmed appointment. Use emergency services for suspected fire or immediate danger rather than waiting for an online response.
