Who we're a fit for
AJ Long Electric has been a residential master electrician in Northern Virginia for 30 years. The same diagnostic skill, communication, and cleanup standards that earned 1,400+ five-star reviews translate directly to small-commercial repair work. We're a strong fit for: small offices and professional-services suites, retail tenants and storefronts, restaurants and small commercial kitchens, property managers handling small portfolios or HOA-managed buildings, and tenant-improvement repair work that happens between leases.
For the full overview of our commercial work — panel upgrades, lighting retrofits, EV charging, inspections, and tenant fit-outs — see our commercial electrical hub. This page focuses specifically on repair and troubleshooting calls.
Commercial repairs we handle most often
Dead outlets and intermittent power
Wall outlets that stop working in offices, retail floors, or back-of-house. Often a tripped GFCI elsewhere on the circuit, a loose connection at the panel, or a failed outlet — we trace and fix.
Tripping breakers under normal load
A circuit that's been fine for years suddenly trips daily. Usually means added load (new equipment, more workstations) pushed it past capacity, or a wiring fault is drawing extra current. We diagnose with clamp meters and either rebalance or add a circuit.
Flickering or failing lights
Buzzing fluorescents, flickering LEDs (often a driver or dimmer-compatibility issue), exit signs out, or display lighting failing. Common in retail and older office stock — usually a fast fix.
Code-correction line items
GFCI updates, missing junction-box covers, emergency-lighting battery replacements, exit-sign repairs, panel labeling — the punch list after a failed inspection. We document everything for the inspector or property manager.
Panel diagnostic and small repairs
Warm panel covers, loose neutral connections, breakers that won't reset, missing labels. We diagnose and repair small-commercial panels (under 400A single-phase). Larger commercial service work goes on the panel-upgrades subservice.
Dedicated-circuit issues
Kitchen equipment circuits failing, server-room outlets browning out, HVAC control-board issues. Often a sizing problem or a worn receptacle — we identify and fix.

Frequently asked questions
Do you handle commercial electrical repairs for small businesses?
Yes. Most of our commercial repair calls are for offices, retail tenants, restaurants, and property managers handling small properties. We use the same diagnostic toolkit (Fluke meters, thermal imaging, circuit analyzers) we run on residential calls — the difference is documentation: we provide COI, W-9, and itemized invoicing on every commercial visit.
What kinds of commercial repairs do you take?
Dead outlets, tripping breakers, flickering lights, failed fixtures, intermittent power, GFCI issues, panel diagnostic, dedicated-circuit problems for kitchen/equipment loads, and code-correction line items after a failed inspection. If it's small-commercial electrical and not industrial-scale, it's in our wheelhouse.
Can you work after hours so we don't have to close?
Yes. Evenings, early mornings, and weekends are normal scheduling for commercial work. For non-emergency repairs we'll coordinate timing with the building manager. For larger jobs we phase the work so the business stays open during peak hours.
What about emergency commercial repairs?
For urgent safety issues — burning smells, sparking, complete power loss — call us immediately. We prioritize commercial emergency calls during business hours. Full 24/7 commercial dispatch isn't our current model; if it's after hours and not a safety emergency, we'll typically schedule same-day or next-day depending on availability.
Do you handle large industrial repairs?
No. Industrial plants, large 3-phase industrial loads, healthcare-specialty work (NEC 517), and high-rise base-building electrical are outside our scope. We'll tell you up front and refer to a specialty contractor when that's the right answer. Our strength is light-commercial repair for offices, retail, restaurants, and property managers.
How do you bill commercial repairs?
We provide a written quote before work starts whenever scope is predictable, and time-and-materials with itemized invoicing for diagnostic-heavy calls. Property managers can be set up on net-30 invoicing after we've worked together once or twice. We carry standard COI levels for property-manager and lease requirements.
