Your electrical service is the backbone of your entire home's power system, encompassing everything from the utility transformer connection through the meter base, service entrance cables, and main panel. When your home's electrical demands exceed the capacity of your existing service, you need a complete service upgrade -- not just a panel swap. AJ Long Electric performs comprehensive electrical service upgrades throughout Northern Virginia, coordinating directly with Dominion Energy for meter disconnects, reconnects, and service capacity increases. Many Northern Virginia homes built in the 1960s through 1980s still operate on 100-amp or even 60-amp service that cannot safely support modern electrical demands including EV chargers, heat pumps, electric cooking, home offices, and multiple high-draw appliances. Our licensed electricians upgrade service entrance cables, meter bases, weatherheads, grounding electrode systems, and main panels as a complete, integrated project. We handle all coordination with Dominion Energy, obtain permits from Fairfax County, Loudoun County, Prince William County, Arlington, or your specific jurisdiction, and ensure the installation meets current NEC standards. A typical service upgrade from 100A to 200A or from 200A to 400A involves replacing the service entrance conductors, upgrading the meter base, installing a new main panel, and verifying the grounding electrode system meets NEC 250 requirements. We complete most residential service upgrades in 1-2 days with minimal disruption.
