professional home EV Charger Installation in Nashua, NH

Licensed electricians installing Tesla, ChargePoint, and Level 2 EV chargers throughout Southern New Hampshire and Northern Massachusetts.

Stop Relying on a Regular Outlet to Charge Your Car

Most electric vehicles come home for the first time plugged into a standard 120-volt outlet. It works, but barely. Charging at that rate can take 24 hours or more to fill a depleted battery. For daily driving, that's not a system, that's a bottleneck.

A Level 2 home charger runs on a dedicated 240-volt circuit, the same type of circuit that powers your dryer or electric range. At that voltage, most EVs charge fully overnight, and many charge in four to six hours. You wake up every morning with a full battery without thinking about it.

Gagnon's Electrical Services installs Level 2 EV chargers for homeowners throughout Nashua, Merrimack, and surrounding towns in southern New Hampshire and nothern Massachusetts. We handle everything from the panel assessment to the finished installation so you're not coordinating between multiple contractors or figuring out the electrical side yourself.

What the Installation Process Actually Looks Like

Step 1: Panel Assessment

Before anything gets installed, we look at your existing electrical panel. We check the amperage, the available capacity, and whether your current setup can support a new 240-volt circuit without upgrades. Most homes in Nashua handle this without issue, but older homes with smaller panels sometimes need an upgrade first.

Step 2: Circuit Installation

We run a dedicated 240-volt circuit from your panel to the location where your charger will be mounted. This is typically in a garage, carport, or on an exterior wall near your parking area. We route wiring cleanly and up to New Hampshire electrical code, and we pull the required permits for the work.

Step 3: Charger Mounting & Connection

We mount your charger at a practical height and angle, make all the connections, and test the unit before we leave. If you already have a charger picked out, we'll install it. If you haven't chosen one yet, we can walk you through the options that make sense for your vehicle and your home.

Step 4: Cleanup and Walkthrough

Before we pack up, we walk you through how the system works and answer any questions you have. We want you to feel confident using your new setup from day one, not troubleshooting it alone a week later. We leave the space clean and the charger ready to use.

EV Charger Choices. Which Charger Should You Install?

There are several reputable Level 2 charger brands on the market, and the right one depends on your vehicle, your preferences, and how you plan to use it. Common options include the ChargePoint Home Flex, the Grizzl-E, the JuiceBox, and chargers made directly by vehicle manufacturers like Tesla and Ford.

A few things worth considering:

  • Amperage

    Most home installations run on a 40 to 50 amp circuit, which supports charging speeds of 30 to 40 miles of range per hour. Some chargers can handle higher amperage if your panel supports it.

  • Smart features

    Many modern chargers connect to your home Wi-Fi and let you schedule charging during off-peak utility hours, which can lower your electric bill. Some also track your energy use over time.

  • Outdoor rating

    If your charger will be mounted outside or in an unheated garage, make sure it carries a weatherproof rating appropriate for New Hampshire winters.

What Nashua Homeowners Say About Our EV Charger Installations

I used Gagnon's electrical services to install the EV charger in my garage. Bill was very friendly from the time he came to do the inspection, was quickly able to figure what we needed as I had the panel in my basement and gave a quick reasonable quote. He and Shawn completed the whole project in a very short time. I'd highly recommend the father and son duo.

Very good experience with Gagnon Electric! The quote was reasonable (given pandemic pricing) for installing a Tesla charging port in our garage. Cleaned up afterwards, you would never know they were well. Stuck to the quote and was able to schedule us in very quickly. We will definitely use them again for future projects.
