Serving Fairfax, Arlington, Alexandria, Loudoun, and Prince William Counties.
Fairfax, Arlington, Alexandria, Loudoun & Prince William Counties
Northern Virginia's commercial electrical landscape is uniquely shaped by the region's position as a major technology, government, and business hub. Loudoun County hosts the largest concentration of data centers in the world, driving demand for mission-critical electrical infrastructure with redundant power systems and massive three-phase installations. Arlington and Fairfax counties are home to hundreds of government contractors and defense firms that require secure, reliable electrical systems meeting federal facility standards. The Tysons Corner area has undergone a dramatic transformation from suburban office parks to a true urban center, with the Silver Line Metro driving demand for mixed-use developments that need sophisticated commercial electrical systems. Along the Route 28 corridor from Manassas through Centreville to Sterling, the growing technology sector is filling office parks and flex spaces that require modern data cabling and high-density power distribution. Reston Town Center continues to attract restaurants, retail, and professional offices, all competing for tenants who expect modern electrical amenities including EV charging stations, LED lighting, and smart building controls. The region's commercial real estate market commands premium lease rates, making energy efficiency upgrades particularly attractive -- a well-executed LED retrofit or power quality improvement can deliver ROI within 18 to 24 months while making properties more competitive for tenant acquisition.
See how we have helped homeowners across Northern Virginia with their commercial services needs.
Challenge
A 45,000 sq ft office complex built in the early 1990s was experiencing recurring breaker trips, dimming lights during peak hours, and tenant complaints about insufficient outlets for modern workstation setups. The building's original 800-amp service and outdated fluorescent lighting were driving operating costs well above market average.
Solution
AJ Long Electric performed a comprehensive electrical overhaul including a main switchgear upgrade to 1,200 amps, a full LED lighting retrofit across all three floors with occupancy sensors and daylight harvesting controls, and installation of additional 20-amp circuits to every office suite to support modern power demands.
Result
Monthly electricity costs dropped 42% within the first quarter after the retrofit. Tenant satisfaction scores improved dramatically, and the building owner secured two new long-term leases within six months, citing the modernized electrical infrastructure as a key differentiator.
Challenge
A newly leased restaurant space in Reston Town Center required a complete electrical build-out for a commercial kitchen with heavy-draw equipment including a convection oven, commercial dishwasher, walk-in cooler, and hood ventilation system. The existing tenant space had only basic office-grade electrical service with no three-phase power.
Solution
We installed a 400-amp three-phase subpanel dedicated to the kitchen, ran heavy-gauge circuits for each piece of commercial kitchen equipment, added GFCI-protected outlets at all wet locations, and installed a grease hood exhaust fan on a dedicated circuit with emergency disconnect. All work was completed during a tight four-week construction timeline coordinated with the general contractor.
Result
The restaurant opened on schedule and passed its health department and fire marshal inspections on the first attempt. The owner reported zero electrical issues during the critical first six months of operation, including during peak holiday service periods.
Challenge
A growing orthopedic practice needed to install an in-office MRI machine, digital X-ray equipment, and additional exam room lighting in their 8,000 sq ft suite. The existing single-phase 200-amp service could not support the imaging equipment's power requirements, and the practice needed dedicated isolated ground circuits to prevent electromagnetic interference.
Solution
AJ Long Electric coordinated with the building owner and Dominion Energy to bring three-phase power to the suite, installed a new 600-amp three-phase distribution panel, ran isolated ground circuits for all imaging equipment, and added dedicated UPS-backed circuits for the practice's electronic health records servers.
Result
The orthopedic practice successfully brought diagnostic imaging in-house, reducing patient referral wait times from weeks to same-day. The clean power installation eliminated the electromagnetic interference issues that had plagued a previous attempt by another contractor.
Challenge
A 12-unit strip mall with a large parking lot was spending over $4,200 per month on electricity, much of it wasted by aging metal halide parking lot fixtures and outdated T12 fluorescent lighting in tenant spaces. Several parking lot lights had failed entirely, creating dark spots that tenants flagged as a safety and liability concern.
Solution
We replaced all 24 parking lot pole fixtures with commercial-grade LED units featuring photocell and timer controls, retrofitted interior lighting in common areas and vacant units with LED tubes and new fixtures, and installed a centralized lighting control panel for the property management company to manage exterior lighting schedules remotely.
Result
The property's combined electricity bill dropped to under $1,800 per month, a savings exceeding 57%. The improved parking lot lighting increased foot traffic to evening-hour tenants, and the property qualified for over $8,000 in Dominion Energy commercial rebates.
Permit requirements for commercial services vary by county. We handle the entire permitting process for you.
Permit Process
Fairfax County requires commercial electrical permits for all new installations, modifications, and tenant build-outs. Applications are submitted through the Land Development Services portal, and commercial permits typically require plan review taking 5-10 business days. A licensed master electrician must be listed on the permit, and inspections must be scheduled at each phase of work.
Inspection Notes
Fairfax commercial inspectors conduct rough-in and final inspections. They verify conduit fill ratios, proper fire-stopping at wall and floor penetrations, NEC-compliant wire sizing for commercial loads, and correct emergency lighting placement per the approved plan. Three-phase installations receive additional scrutiny for phase balancing and disconnecting means.
Special Requirements
Permit Process
Loudoun County processes commercial electrical permits through the Department of Building and Development with typical plan review times of 7-14 business days for commercial projects. The county's rapid growth along the Route 28 and Dulles corridors means inspectors are in high demand, so scheduling inspections early is critical to maintaining project timelines.
Inspection Notes
Loudoun commercial inspectors pay close attention to data center-grade electrical work given the county's concentration of data facilities. They verify proper grounding and bonding for sensitive equipment, conduit specifications, and generator transfer switch installations.
Special Requirements
Permit Process
Prince William County commercial electrical permits are processed through the Development Services department. Plan review for commercial projects typically takes 5-10 business days. The county offers expedited review for an additional fee, which can reduce turnaround to 2-3 business days for time-sensitive projects.
Inspection Notes
Prince William commercial inspectors verify NEC compliance, proper labeling of all commercial panels and disconnects, and correct sizing of feeders and branch circuits. They require accessible panel directories and may request load calculations for larger installations.
Special Requirements
Permit Process
Arlington County has a rigorous commercial permit process managed by the Inspections Services Division. Commercial electrical permits require architectural and engineering plan submissions, with plan review typically taking 10-15 business days. Arlington's dense urban environment and proximity to federal facilities mean commercial electrical work may require additional security or coordination considerations.
Inspection Notes
Arlington commercial inspectors are among the most detail-oriented in Northern Virginia. They verify proper separation of low-voltage and line-voltage systems, check for compliance with the latest NEC edition adopted by the state, and require thorough documentation of all commercial installations including as-built drawings.
