The home base for the DMV's electrical work since 1996
Our Fairfax headquarters at 2724 Dorr Ave, Suite 102 is where the business has been based since AJ Long Electric was founded in 1996. This is the office where mail goes, where dispatch runs, and where the master electricians who anchor the company are based. If you call (703) 997-0026, you reach Fairfax. We're open 24 hours for emergency electrical situations across Northern Virginia.
Fairfax County's electrical landscape is uniquely demanding. The City of Fairfax and surrounding communities span every housing era from 1950s split-levels in Mantua and Mosby Woods to the 1970s colonials around Kings Park, the contemporary smart homes rising throughout the county, and the dense commercial corridors near George Mason University. We've worked in every one of them.
Most of our Fairfax work falls into a few categories: panel upgrades for homes that have outgrown their 100A or 150A service (the modern HVAC + EV charger + induction-cooktop load just doesn't fit anymore), EV charger installations driven by the shift to Tesla and ChargePoint hardware, aluminum-wiring remediation in the late-1960s housing stock around Robinson Secondary, and the Federal Pacific / Zinsco panel replacements that insurance companies and home-inspection reports keep flagging.
We hold a Virginia Class A contractor license (#2705031092) issued by the Virginia Department of Professional and Occupational Regulation (DPOR) — you can confirm any Fairfax electrician's license there before hiring. We pull permits through Fairfax County Land Development Services, which enforces the National Electrical Code (NFPA 70) through Virginia's Uniform Statewide Building Code on the 2020 NEC cycle. Our technicians know the local inspectors and the patterns of how jobs in different parts of the county get scheduled — meaning your project moves through inspection without the delays that trip up out-of-area contractors.

Panel sizing for Fairfax homes
The right service size depends on the home's era and how much of it runs on electricity. These are the typical Fairfax scenarios we size against a full NEC Article 220 dwelling-unit load calculation:
| Fairfax home type | Typical existing service | Recommended service |
|---|---|---|
| 1950s Mantua / Mosby Woods split-level, gas heat | 100A | 200A |
| 1970s Kings Park colonial adding an EV charger | 100A–150A | 200A |
| Contemporary smart home, heat pump + induction | 150A–200A | 200A |
| Large or all-electric home, dual EV + workshop | 200A | 400A |
Panel sizes are starting points, not quotes — the binding number comes from the NEC 220 load calculation we run for your specific square footage, appliances, and planned additions.

What Fairfax customers say
Reviews from this Google Business Profile
“AJ Long consistently performs great work. They were able to install the Tesla charger without having to cut any holes in the drywall in my basement. This was important for me since I had special drywall on my ceiling to soundproof noise between the floors. The work was done very cleanly and professionally. Sai and Bo were great! Thanks guys.”
“Terrific experience with AJ Electric from start to finish. The team was responsive, punctual, and incredibly efficient. The quality of the work was excellent, and their pricing was fair and transparent, especially given how quickly they were able to schedule and complete the job. It’s rare to find a company that delivers both great craftsmanship and great communication, but AJ Electric did exactly that.”
“They were upfront a honest with me during the troubleshooting & estimate process. When they did the actual "heavy up" and bringing our house up to code, their work was great. Professional service, I highly recommend them. We already have other projects we will be hiring them for.”
“Fantastic job hanging my new stairway light! Your company was perfect from scheduling to completion. The electrician was professional and very nice. He did an excellent job and I couldn’t be happier. The cost was very reasonable and I will definitely use your services again. Thank you!”
“Technician was kind and respectful. He made a recommendation that made our project even better and added an additional outlet that we didn’t know we needed, but already use extensively. Work was quick and done right the first time.”
