Electrical Installations in Naperville, IL — Residential & Commercial

When something needs to be installed in your home or business — a new panel, an EV charger, a run of recessed lights, a dedicated circuit for a piece of equipment — the install only goes well if it’s done by an electrician who’s pulled the same permit a hundred times and knows what the inspector is going to look for. Cob Services LLC has been doing electrical installations in Naperville, IL for more than ten years, and we work on both sides of the meter: homes and businesses.

Searching for “electrical installations near me” in Naperville and not sure who picks up the phone? You’ll get Alexandr — owner, licensed Illinois electrician (License #26-00032356), and the person who walks every install before we quote it. No call center, no project hand-off, no surprise crew you didn’t hire showing up at the door.

Residential Electrical Installations in Naperville

Most install calls we get from Naperville homeowners fall into a handful of buckets. Here’s how we handle each one, and what tends to make these jobs go sideways when an unlicensed handyman tries them.

Electrical panel installations and service upgrades

A lot of Naperville homes built before the mid-90s came with 100-amp service, and that panel was never sized for a modern household running AC, an EV in the garage, an induction range, and a finished basement. We install 200-amp panels (and 400-amp on larger custom homes), replace failed Federal Pacific and Zinsco panels, and coordinate the meter pull with ComEd so the power’s only off for a few hours, not a full day. Permit and final inspection through the City of Naperville’s building department are part of the price — we don’t quote it as an “extra”.

EV charger installations

Level 2 EV charger installs come down to three things: where the car parks, where the panel is, and whether the panel can carry another 40–60 amp circuit. We install Tesla Wall Connectors, ChargePoint, Wallbox, JuiceBox, and hardwired NEMA 14-50 outlets. If the existing service can’t handle the load, we’ll tell you upfront — and quote the panel upgrade separately so you can see what each piece costs. Permits get pulled with the City of Naperville, and we’ll point you at ComEd’s EV time-of-use rate plans, which usually pay back the install faster than people expect.

Lighting installations — recessed, interior, exterior

Lighting is half design, half wiring, and the design half is where most installs go wrong. Recessed cans spaced too far apart leave dark patches. LEDs on the wrong dimmer flicker. Vanity fixtures put in the wrong spot wash out anyone trying to use the mirror. We sit down with you, walk the space, and lay out a plan before we cut a single hole in the ceiling. Kitchen under-cabinet, bathroom vanity, recessed wafer retrofits, two-story foyer chandeliers, basement work on occupancy sensors, exterior soffit and landscape — we install all of it.

Outlets, switches, and dedicated circuit installations

A lot of “I just need an outlet installed” jobs in older Naperville homes turn into something bigger once we’re behind the wall. Two-prong outlets need a real ground path, not a cheater plug. Kitchens and baths need GFCI. Bedrooms need AFCI. Dedicated circuits get installed for window AC units, sump pumps, freezers in the garage, home gyms, and home offices that run a desktop plus three monitors plus a laser printer. We size the circuit for the load, run the home run back to the panel correctly, and label the breaker so you (or the next homeowner) can find it again.

Ceiling fan and smoke detector installations

Ceiling fans go on a fan-rated box. Most original light-fixture boxes are not fan-rated, so a “swap the fixture for a fan” install is really a “rebuild the box, run new wiring, and then install the fan” job. We do that work the right way, including separate switches for fan and light, and downrod and brace work for vaulted ceilings. Smoke detector installs in Illinois are tightly regulated — hardwired, interconnected, with battery backup, in every bedroom, outside every sleep area, and on every level. If you’re selling your house and the inspector flagged battery-only smokes, we handle the rewire and the sign-off.

Hot tub, pool, and outdoor electrical installations

Anything where electricity meets water gets a different level of attention. Hot tub circuits need a 50-amp or 60-amp dedicated GFCI feed, a disconnect within sight of the tub, and bonding back to the equipment. Pool installs add the copper bonding ring around the pool itself, weather-rated pump outlets, and underwater light circuits run on their own GFCI. We pull the permit, get the inspection, and sign off on the bonding because the inspector will check it and “it works” isn’t the same as “it passed”.

Commercial Electrical Installations in Naperville

Commercial installs run on a different clock. Tenants need to open. GCs need rough-in done before drywall lands. Property managers need work scheduled around tenant business hours. We install for restaurants, retail, offices, multifamily, hotels, and grocery — with a crew that shows up badged, quiet, and out of the customer-facing space.

Commercial install work on existing buildings

A lot of the commercial work we install isn’t part of a brand-new build. A property manager needs four new dedicated circuits added for a tenant’s new equipment. An office adds a server room and needs the panel reworked. A restaurant gets a new piece of kitchen equipment and the breaker it landed on can’t carry it. We handle these one-off installs and small upgrades on existing commercial spaces across Naperville, Aurora, Lisle, Plainfield, and Bolingbrook — without pulling you into a full remodel scope. For ground-up commercial wiring, tenant build-outs of white-box shells, and projects involving service entrance and ComEd coordination, see our new construction electricians page.

Commercial panel, sub-panel, and switchgear installations

Older Naperville commercial buildings — office parks along Diehl Road, retail along the Route 59 corridor, downtown buildings — were wired for the loads of their era. New tenants bring new loads. We install commercial panels, sub-panels, switchgear, and transformer feeds, and we coordinate the ComEd side when a service drop or meter relocation is part of the work. That’s the piece that quietly adds weeks to a project if it isn’t started early, so we start it early.

Commercial lighting installations

Lighting installs in a commercial space are about more than fixtures. Photocell controls on parking lot poles, occupancy sensors for offices and back-of-house, emergency and exit lighting that meets Illinois code, sign and pylon circuits for retail. We design and install full commercial lighting packages, retrofit older buildings to LED for energy savings (often with utility rebate paperwork handled for you), and handle storefront and pylon sign circuits for retail tenants.

Specialty commercial installations

The work that doesn’t fit a category but still has to get done: walk-in cooler and freezer dedicated circuits and refrigeration alarm wiring for grocery and restaurant. Hood circuits, range and fryer hookups, and small-appliance branch circuits for kitchens. Server room dedicated circuits and conference room floor boxes for offices. Laundry room high-load circuits for hotels and multifamily. EV charging station installs for guest parking and Illinois multifamily compliance. If it’s something a building needs installed and it’s powered, we install it.

Working with Naperville’s Permit & Inspection Process

Most installs we do in Naperville need a permit. Panels, service upgrades, EV chargers, hot tubs and pools, additions, and significant remodels all go through the City of Naperville’s Building Department, which has its own submission, plan review, and inspection workflow. Surrounding suburbs — Aurora, Plainfield, Bolingbrook, Lisle, Downers Grove — each have their own process, too. We pull permits in our own contractor name, submit load calculations the city expects, and schedule rough-in and final inspections around your project timeline. ComEd coordination — the meter pull for a service upgrade, a new commercial drop — is part of the job, and we start that conversation early because it’s the part that adds weeks if it isn’t.

Frequently Asked Questions About Electrical Installations in Naperville

How much does an electrical installation cost in Naperville?

It depends on what’s being installed. A single outlet install runs a couple hundred. A 200-amp panel upgrade typically lands between $2,500 and $4,500 in our area, depending on whether the meter and service drop need work too. A Level 2 EV charger install is usually $800–$1,800 if the panel can handle it, more if it needs a panel upgrade first. We give you a flat price after walking the job — no hourly surprise on the invoice.

Do I need a permit for an electrical installation in Naperville?

For most jobs that involve new circuits, panel work, EV chargers, hot tubs, pools, additions, or significant lighting work — yes. Replacing an existing fixture or outlet usually doesn’t need one. We pull the permit in our contractor name when the job calls for it, so you’re not chasing City Hall.

Are you licensed and insured for both residential and commercial installations?

Yes. License #26-00032356, fully bonded and insured, and we install on both residential and commercial jobs every week.

How long does an electrical installation take?

An outlet or switch install is a same-day job, often under an hour. A panel upgrade is usually a one-day job, with the power off for half of it. EV chargers run half a day to a full day. Larger commercial installs and equipment changeouts run on the customer’s schedule — we work around your hours so the install doesn’t shut down the space. (Timelines for ground-up new builds and rough-in/trim-out work are covered on our new construction page.)

Do you install equipment I bought myself?

Most of the time, yes — Tesla Wall Connectors, ceiling fans, light fixtures, smart switches, hot tubs you already had delivered. Two caveats: the equipment has to be UL-listed, and if the manufacturer’s warranty requires a licensed install (which most do), we’ll document it for you. If we think the equipment is wrong for the job, we’ll tell you before we put it on the wall.

Can you handle an installation in an older Naperville home?

Yes — and that’s most of what we do. Knob-and-tube, cloth-insulated wiring, aluminum branch circuits, and Federal Pacific or Zinsco panels are all common in pre-1980s housing stock around downtown Naperville and the older near-suburbs. We install around what’s there, replace what’s failing, and make sure the new work is code-compliant with the old wiring it ties into.
