Our 4-Step EV Charger Installation Process
1. Panel & Power Check
First, we look at your electrical panel to make sure it has the room to handle a new charger. We calculate the power draw for your home or shop to ensure you won't be tripping breakers the second you plug in your car.
2. Custom Wiring Layout
We map out the best path to run the wires from your panel to the charger. Our goal is to keep the run as short and clean as possible, using high-quality conduit that keeps the setup looking professional and out of the way.
3. Mounting & Connection
We bolt the charging station to the wall and handle all the heavy-duty wiring. Whether it’s an indoor garage or an outdoor parking spot, we make sure the unit is rock-solid and all connections are sealed tight to meet local electrical codes.
4. Live Power Test
Once it's on the wall, we flip the breaker and test the output. We check the speeds and the safety shut-offs to make sure the unit is talking to your car correctly. We don't pack up until we see that it’s actually charging.
Residential EV Charger Installation
Charging your vehicle at home should be convenient and efficient. We install Level 2 EV chargers that significantly reduce charging times compared to standard outlets.
Panel Capacity Assessment
Before installation, we confirm your electrical panel can safely support the additional load and recommend upgrades if needed.
Dedicated 240V Circuits
Level 2 chargers require a dedicated 240V circuit. We ensure your system is properly configured to handle the demand without overloading your home.
Smart Charger Options
We install modern smart EV chargers that allow scheduling, usage tracking, and energy management directly from your smartphone.
Commercial EV Charger Installation
We help businesses meet the growing demand for EV charging. Whether for employees, customers, or fleets, we design systems built for performance and scalability.
Our commercial installations account for:
Amperage Capacity

Frequently Asked Questions About EV Chargers
What are the different types of EV chargers?
There are three main types:
- Level 1 Chargers plug into a standard 120V household outlet and provide slower charging, ideal for overnight use.
- Level 2 Chargers use a 240V outlet and offer much faster charging, making them the most common choice for homes and workplaces.
DC Fast Chargers (Level 3) provide the fastest charging speeds and are typically found at public stations along highways and major routes.
How fast do EV chargers work?
Charging speed depends on the charger type and your vehicle’s battery capacity.
- Level 1 chargers add about 2 to 5 miles of range per hour.
- Level 2 chargers deliver roughly 10 to 30 miles of range per hour.
- DC fast chargers can add up to 60 to 80 miles of range in about 20 minutes.
What connector types are used in North America?
Common connector types include:
- J1772 for Level 1 and Level 2 charging
- CCS (Combined Charging System) for DC fast charging
- CHAdeMO used by some Japanese and Korean manufacturers
Tesla connector designed for Tesla vehicles, with adapters available for compatibility
How do I find public charging stations?
Public charging networks vary by region and provider. Many EV manufacturers offer built-in navigation systems or mobile apps that show nearby charging stations and real-time availability.
How much does it cost to charge an EV?
Charging costs depend on local electricity rates, charger speed, and the network’s pricing model. Some stations offer free charging, while others charge per kWh consumed or by time connected.
What’s required for home EV charger installation?
Installing a Level 2 charger typically requires a dedicated 240V circuit and professional installation by a licensed electrician. Utility providers may offer rebates or incentives to help offset installation costs.
How do I maintain my EV charger safely?
Regularly inspect charging cables and connectors for wear or damage. Ensure equipment meets safety standards and follow manufacturer guidelines to protect battery health and maximize performance.
