A-1 Heating, Air Conditioning & Electric installs Level 2 home EV chargers in Boise and across the Treasure Valley, licensed under Idaho contractor license RCE-873 / 012266. A-1 also installs commercial EV charging stations for Boise businesses, workplaces, and multi-unit properties, including the load assessment, dedicated circuit, and permitting each job needs.
Every charger is installed by licensed electricians who pull the permit, size the circuit to the equipment, and verify the install passes inspection before they leave.
A-1 Heating, Air Conditioning & Electric is the Boise electrical contractor homeowners call to install a Level 2 charger in the garage, carport, or driveway. Most drivers who charge at home want a 240-volt Level 2 unit because it fits an overnight routine. A Level 1 cord plugged into a standard outlet adds only about 3 to 5 miles of range per hour, while a Level 2 charger on a 240-volt circuit adds roughly 25 to 40 miles per hour, according to U.S. Department of Energy and Department of Transportation charging data. For a Boise commuter, that’s the difference between a car that’s never quite full and one that’s ready every morning.
The work is handled by licensed Boise electricians, not a subcontractor sent to your door. That matters because a home charger is a permanent 240-volt circuit tied into your panel, and the National Electrical Code requires a licensed electrician for permanent EV charger installation.
Level 2 charging is the right choice for almost every Boise household that drives daily. Level 1 uses the 120-volt cord that ships with the car and needs no new wiring, but it charges slowly enough that it rarely keeps up with a normal commute. Level 2 runs on a dedicated 240-volt circuit and recharges most EVs overnight in about 6 to 12 hours depending on battery size.
The practical question is not which level charges faster, since Level 2 clearly does. It’s whether your home’s electrical system can support the new circuit without changes. That’s where the panel comes in.
Some Boise homes need an electrical panel upgrade before a Level 2 charger can be added safely, and some do not. A Level 2 charger typically draws 40 to 60 amps, so the panel has to have both the spare capacity and an open slot for a new double-pole breaker. Newer Boise and Eagle homes built with 200-amp service usually have room. Older homes in the Boise Bench, the North End, or a 100-amp panel often do not.
A-1’s electricians run a load calculation first to see what your panel can handle. If the panel is full or undersized, we’ll tell you before any work starts, and can then provide you with additional options such as an EV load manager or service upgrade.
An EV load manager is often the lower-cost route. It balances the charger against the home’s existing electrical loads so the charger draws full power only when spare capacity is available, which can let an older 100-amp panel support a Level 2 charger without a full service upgrade. Homeowners who do upgrade the panel sometimes pair the work with standby generator installation, which keeps the whole home covered during a Treasure Valley power outage.

A-1 Heating, Air Conditioning & Electric installs both Tesla and non-Tesla EV chargers for Boise homes and businesses. Tesla’s connector, now published as the SAE J3400 (NACS) standard, is supported by most major brands, and the Tesla Universal Wall Connector combines NACS and J1772 in one unit so it charges a Tesla, a Ford, a Rivian, a Hyundai, or a GM vehicle without a separate adapter. That unit delivers up to 44 miles of range per hour at a 48-amp output.
A-1 installs whatever charger you buy, whether that’s a Tesla Wall Connector, a ChargePoint, an Emporia, a Grizzl-E, or another brand. The electricians wire the unit you chose to the correct circuit. If you haven’t picked one yet, we’ll walk you through the amperage and connector choice for your vehicle before we quote the job.
A-1 Heating, Air Conditioning & Electric installs commercial EV charging stations for Boise workplaces, retail sites, apartment complexes, and fleet yards. A commercial install starts with a service and load assessment, because a bank of charging ports draws far more than a single home unit and often needs a dedicated subpanel or a service upgrade. The commercial electrician team handles the design, the trenching and conduit where ports sit away from the building, the permitting, and the utility coordination.
For a Boise employer, on-site charging is a low-cost benefit that keeps staff and customers parked at your property longer. For a property manager, it’s an amenity tenants increasingly expect. A-1 scopes each project to the number of ports you need now and the capacity you’ll want to add later, so the infrastructure doesn’t have to be rebuilt when demand grows.
The cost of an EV charger installation in Boise depends on four things: the charger you choose, the distance from your electrical panel, whether the panel needs an upgrade, and whether the run is indoors or requires outdoor conduit. A straightforward garage install next to the panel is the low end. A long wire run, an outdoor pedestal, or a panel upgrade raises it.
Boise-area buyers should factor in the Idaho Power residential EV charger rebate, currently $200 as of 2026, plus Idaho Power’s EV time-of-use rates that lower the price of charging during off-peak overnight hours. Note that the federal 30C EV charger tax credit expired on June 30, 2026, so it is no longer available for new installs. A-1 Heating, Air Conditioning & Electric provides a free written estimate for every EV charger project, so you see the full number before you commit.
Installing a home EV charger in Idaho requires a permit and a licensed electrician, and A-1 handles both. The National Electrical Code treats a Level 2 charger as a permanent 240-volt circuit, which must be installed to code and inspected. A-1 pulls the electrical permit, installs the circuit and equipment to NEC and Idaho Division of Building Safety standards, and schedules the inspection. Skipping the permit can create insurance and resale problems later, which is why A-1 does every job by the book.
A-1 Heating, Air Conditioning & Electric has served the Treasure Valley since 1956 and is a 15-time Dave Lennox Award winner and a 2025 Top 25 Contractor in North America. For an EV charger, that track record means licensed electricians under license RCE-873 / 012266, honest load assessments, permitted work, and a company that will still be here to stand behind the install. A-1 Heating, Air Conditioning & Electric also covers EV charger installation in Nampa and EV chargers in Caldwell, and is licensed in Oregon for the Ontario area.
