Certified installation for Tesla, ChargePoint, and all major EV charger brands.

Wake up to a fully charged vehicle every morning with a professionally installed Level 2 EV charger. Unlike Level 1 charging on a standard 120V outlet that adds only 3-5 miles of range per hour, a Level 2 charger on a dedicated 240V circuit delivers 25-40 miles per hour, fully charging most EVs overnight. Our certified installers handle everything from initial load calculation and panel assessment to permitting and final commissioning. We are experienced with all major charger brands including Tesla Wall Connector, ChargePoint Home Flex, JuiceBox, Grizzl-E, and ClipperCreek, and we ensure compatibility whether you drive a Tesla, Ford, Rivian, Chevy, BMW, or any J1772-equipped vehicle. We size your circuit to the NEC 625 continuous load rule (125% of charger amperage) and install with proper GFCI protection on a dedicated circuit. Our team also helps you navigate available federal tax credits and local utility rebates so you save on installation costs. Whether you need a garage-mounted hardwired unit or a weatherproof outdoor NEMA 4-rated installation for your driveway, we deliver a safe, code-compliant setup optimized for your daily charging needs.

Our licensed electricians are ready to assist you in Northern Virginia.
Serving Fairfax, Arlington, Alexandria, Loudoun, and Prince William Counties.
Fairfax, Arlington, Alexandria, Loudoun & Prince William Counties
Northern Virginia is one of the fastest-growing EV markets on the East Coast, driven by the region's high household incomes, long commuting distances, and strong environmental awareness. The typical NoVA commuter drives 30-50 miles daily between residential areas in Fairfax, Loudoun, and Prince William counties and employment centers in Tysons, Arlington, and Washington DC, making Level 2 home charging essential rather than optional. Dominion Energy's residential electricity rates, while rising, still make home EV charging significantly cheaper than gasoline -- typically equivalent to paying $1.00-$1.50 per gallon. The region's housing stock presents diverse installation challenges: colonial homes in McLean and Vienna with detached garages require longer circuit runs, while townhomes throughout Ashburn and Reston demand compact installations that satisfy HOA requirements. Virginia's EV-friendly policies, including HOV lane access for EVs and state tax incentives, continue to accelerate adoption. The climate also plays a role -- Northern Virginia's cold winters reduce EV range by 15-25%, making reliable home charging even more critical so drivers start each day with a full battery. Our team understands the specific permitting requirements across Fairfax, Loudoun, Prince William, and Arlington counties, and we maintain relationships with local inspectors to ensure smooth project completion.
See how we have helped homeowners across Northern Virginia with their ev charger installation needs.
Challenge
The homeowner purchased a Tesla Model Y and needed Level 2 charging, but their detached garage was 85 feet from the main panel. The 1978 colonial had a fully loaded 200-amp panel with no available breaker slots.
Solution
We installed a 60-amp subpanel in the garage fed by a buried conduit run from the main panel. A Tesla Wall Connector was hardwired to a dedicated 60-amp circuit with GFCI protection, and we added a load management device to prevent overloading the main service.
Result
The homeowner now charges their Tesla overnight at the full 48-amp rate, gaining approximately 44 miles of range per hour. The subpanel also provides capacity for a future second EV charger.
Challenge
A two-EV household in a Brambleton townhome community needed charging for both a Rivian R1S and a Chevy Bolt. The attached single-car garage had limited wall space and the panel was on the opposite side of the home.
Solution
We ran a dedicated 100-amp feeder through the basement ceiling to a new garage subpanel. Two ChargePoint Home Flex units were installed with load-sharing capability, allowing both vehicles to charge simultaneously at reduced rates or one vehicle at full speed.
Result
Both vehicles charge overnight without issue. The load-sharing feature automatically balances power between the two chargers, and the homeowners save over $200/month compared to their previous gas costs.
Challenge
This 1960s split-level had no garage, and the homeowner needed an outdoor EV charger for their Ford Mustang Mach-E parked in the driveway. The panel was in the basement, requiring a long exterior conduit run through a finished living space.
Solution
We installed a NEMA 4-rated weatherproof ChargePoint Home Flex on a custom mounting post near the driveway. The circuit was routed through the crawl space beneath the addition to avoid disrupting finished walls, emerging through the foundation wall with proper sealing.
Result
The outdoor installation withstands Northern Virginia's hot summers and freezing winters without issue. The homeowner charges their Mach-E to full every night and appreciates the clean, professional-looking pedestal mount.
Challenge
A Great Falls estate owner with a Rivian R1S, Tesla Model S, and a Porsche Taycan needed three EV chargers in their multi-bay garage. The existing 200-amp service was insufficient for the combined charging load along with the home's existing demand.
Solution
We coordinated a full service upgrade to 400-amp service with Dominion Energy, installed a new 200-amp subpanel in the garage, and mounted three dedicated chargers with an intelligent load management system that prioritizes charging based on the owner's daily schedule.
Result
All three vehicles charge overnight using scheduled load management that shifts power between chargers based on departure times. The 400-amp service provides ample headroom for the estate's total electrical needs.

Get answers to common questions about our ev charger installation services.
Level 1 charging uses a standard 120-volt outlet and adds about 3-5 miles of range per hour. Level 2 charging uses a 240-volt dedicated circuit and adds 25-40 miles per hour, fully charging most EVs overnight. For daily drivers in Northern Virginia with commutes, Level 2 is essential for convenience.
Not always. Many homes with 200-amp service have sufficient capacity for a 50-amp EV charger circuit. However, older homes with 100-amp panels or heavily loaded systems may require an upgrade. We perform a load calculation during our assessment to determine your needs.
Yes, we install Tesla Wall Connectors, Tesla Universal Wall Connectors, and all other major brands including ChargePoint, JuiceBox, Grizzl-E, and ClipperCreek. Tesla does not require brand-specific certification for Wall Connector installation by licensed electricians.
Most homeowners install EV chargers in their garage near the vehicle's charge port location. We can also install outdoor-rated chargers in driveways or carports with weatherproof NEMA enclosures. Consider your vehicle's charge port location (front, rear, left, right) when choosing placement.
A typical EV charger installation takes 2-4 hours when the panel is nearby with available capacity. If we need to run a longer circuit, install a subpanel, or make panel modifications, the job may take 4-6 hours. We complete all installations in a single visit.
Yes, the federal government offers a tax credit of up to 30% of installation costs through the Alternative Fuel Vehicle Refueling Property Credit. Some utility companies and local jurisdictions offer additional rebates. We provide the documentation you need for tax credit claims.
Absolutely. We install NEMA 4-rated (weatherproof) EV chargers and enclosures for outdoor installations. These are fully protected against rain, snow, and extreme temperatures common in the DC metro area. Outdoor installations require a few additional considerations for conduit and mounting.
EV charger installation in the Washington DC metro area typically costs $800-$2,500 for a complete Level 2 installation. The price includes the dedicated 240V circuit, labor, and permit fees. Panel upgrades, if needed, add $1,800-$4,500. The charger unit itself ranges from $300-$700 depending on features.
A 50-amp circuit is recommended for future-proofing. While many current EVs charge at 32-40 amps, newer vehicles increasingly support faster home charging. A 50-amp circuit with a 40-amp charger gives you room to upgrade later without rewiring. The installation cost difference is minimal.
Yes, with limitations. Some smart chargers support load sharing between two vehicles, though this splits the charging speed. Alternatively, we can install a single 14-50 outlet that two vehicles share with a portable EVSE. For fastest charging of two EVs, we recommend two dedicated circuits.
Yes, EV chargers require a dedicated 240V circuit that powers only the charger. This prevents overloading and ensures consistent, safe charging. The National Electrical Code requires this for all Level 2 EV charging installations. We install appropriately sized circuits based on your charger's requirements.
Top-rated home EV chargers include ChargePoint Home Flex, Tesla Wall Connector, JuiceBox, and Grizzl-E. For non-Tesla vehicles, ChargePoint and JuiceBox offer excellent smart features and reliability. Tesla owners benefit from the Wall Connector's seamless integration. We install all major brands and help you choose based on your needs.
