EV Charger Repair in Boston, MA
Diagnosing why the charge stopped
A charger that has stopped working is usually one of four things, and telling them apart is most of the job. It can be the supply: a tripping breaker, a loose lug, a neutral or ground problem in the run. It can be the unit: failed internal relay, water ingress, a burned connector face. It can be the vehicle's own charge port or its charging settings. Or it can be a communication fault on a networked unit that has nothing wrong with it electrically at all. We test rather than swap. That order matters because the most expensive assumption in charger repair is that a unit which will not deliver current must be dead. Older Boston installs bring their own patterns. Conduit run along an exterior wall takes freeze-thaw cycles and road salt, and outdoor units that were never in a NEMA-rated enclosure for the exposure show corrosion at the terminations long before the electronics fail. Chargers installed by a general electrician in a rush sometimes land on an undersized conductor that worked fine until the car started asking for full current in cold weather. What you get is the fault identified, the fix quoted before it happens, and the supply side checked properly rather than left as the thing nobody looked at.
A repair visit starts with the fault history: when it stopped, what the unit displays, and whether it charges on a different circuit or a different car. We then test the supply under load, inspect the terminations and the enclosure, and read whatever fault log the unit keeps. You get the diagnosis in plain terms, a price for the repair and a price for replacement where both are real options, and the supply-side findings documented. If the original install was not to code, you get that in writing too.

Comprehensive EV Charging Services in Boston
Tailored to Your Needs
Ten services, from a single garage circuit to a commercial lot. The install work splits by what the panel can carry and by who owns the parking. Repair and maintenance keep an existing charger delivering full current instead of quietly derating.
A load study decides how many commercial ports a building can actually carry.
A load calculation decides whether the charger needs new service or a shared circuit.
Diagnosis separates a charger fault from a circuit fault before anything gets replaced.
Board approval and metering decide a condo charger install more than the wiring does.
An annual check catches loose terminations and enclosure failures before they cook the connector.
Charger circuits are licensed electrical work, permitted and inspected like any new circuit.
Circuit size and mounting position set how fast a Wall Connector actually charges.
A Level 2 circuit turns overnight parking into a full battery every morning.
Fleet charging is designed from the duty cycle, not from the number of vehicles.
A 240-volt outlet lets a portable charger do most of what a wall unit does.
Where we install across Greater Boston
EV charging installed by licensed Boston electricians
Outside Boston we work in Cambridge, Somerville, Newton, Quincy and Medford. Each one files electrical permits through its own office and sits in its own utility territory, so the rebate route and the inspection timing shift from city to city. We confirm both before the first invoice.
Frequently Asked Questions
EV Charging can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
Frequently Asked Questions about ev charger installation Boston MA
How much does EV charger installation cost in Boston?
Most Boston home installs land somewhere between roughly $1,700 and $4,000, and the spread is almost entirely about the panel and the distance. A charger mounted beside an existing panel with spare capacity sits at the bottom of that range; a run to a detached garage, or one that needs a panel upgrade first, sits at the top. We price after we have looked at the panel and the parking spot, because a number given before that is not a quote.
Do I need a permit to install an EV charger in Boston?
Yes. A new charger circuit is electrical work, and Massachusetts requires that it be filed with the municipal wiring inspector before it gets energized. We pull the permit under our license and meet the inspector for the rough and final. If an installer offers to skip that step, the circuit never gets inspected and the paperwork you need for a rebate does not exist.
Can my condo association block me from installing an EV charger in Massachusetts?
Not unreasonably. The Massachusetts Right-to-Charge law limits what a condo association can refuse when a unit owner wants a charger at their own parking space, though the association can still set reasonable conditions about routing, metering and insurance. What actually stalls these projects is incomplete paperwork rather than a flat refusal. We prepare the scope drawing, the equipment specification and the electrical detail the board needs to vote on.
Does installing an EV charger require a panel upgrade?
Sometimes, and it comes down to the load calculation rather than the age of the panel. A 100-amp service with electric heat or a large air conditioner often has no room for a 40-amp charger circuit, while another 100-amp house has plenty. We run the calculation during the site visit. Where the load is tight, a load-management device can occasionally solve it for less than a service upgrade would.
What rebates are available for EV charger installation in Massachusetts in 2026?
The state runs MOR-EV, the utilities run charger and make-ready rebates through Mass Save, and MassEVIP grants cover charging at multifamily buildings, workplaces, fleets and public sites. The federal residential charger credit ended on June 30, 2026, so a charger placed in service after that date does not qualify. Amounts and eligibility change, so we confirm what your address and utility actually qualify for before you commit to equipment.
How long does EV charger installation take in Boston?
The wiring on a straightforward residential install is usually a single day. What sets the overall timeline is the permit and inspection sequence, equipment lead time, and any utility work if the service itself has to change. A condo or commercial project adds the approval step ahead of all of that. We give you the sequence in writing, with the inspection date, so you know what is waiting on us and what is waiting on somebody else.
Frequently Asked Questions about EV Charger Repair
Why does my EV charger keep tripping the breaker?
A charger that trips under load is usually telling you about the circuit, not about itself. Common causes are a loose termination heating up, an undersized conductor for a continuous 40-amp draw, moisture in an outdoor connection, or a genuine fault in the unit's internal electronics. Resetting it repeatedly is the one thing to avoid: a breaker that trips on load is doing its job.
Is it worth repairing an EV charger or should I replace it?
If the fault is in the supply, repair it and keep the unit. If the fault is inside a unit that is out of warranty and several years into its life, replacement is often the better value, particularly where the newer generation charges faster on the same circuit. We price both once the diagnosis is done rather than deciding for you.
Can you repair a charger another company installed?
Yes, and a fair number of our repair calls are exactly that. We check the original circuit as part of the diagnosis, because a fault that shows up months after an install is frequently a termination or a conductor sizing issue rather than the hardware. If we find something that was not to code, we document it and quote the correction.
My charger works but charges slowly. Is that a fault?
Often it is not. Chargers derate deliberately when the unit is hot, when the vehicle asks for less, or when a load-management device is sharing current with the rest of the building. Cold batteries also accept charge slowly regardless of the charger. We check whether the unit is actually delivering what the circuit allows before treating slow charging as a fault.
