Central Indiana is not a single city. It is a region built from eight distinct counties, each with its own housing stock, growth patterns, electrical code jurisdictions, and service needs. A homeowner in Zionsville faces different challenges than a business owner on the US-31 corridor in Greenwood. A Shelbyville resident with a 1970s ranch home has different electrical priorities than a new-construction buyer in McCordsville. What they share is a need for a licensed, accountable electrician who actually knows the area.

That is what we have built. Zach and Kara Zimmerman started this company to serve Central Indiana the right way, with our own licensed team, real local knowledge, and a commitment that extends to every corner of the eight-county metro. This guide walks through our full service area, what we do in each county, and how to get started.

What Is Central Indiana? Our 8-County Service Area

When people ask what counties are in Central Indiana, the answer depends on who is defining the boundaries. For most regional planning purposes, Central Indiana refers to the Indianapolis metro statistical area and the surrounding ring of communities that form the economic and geographic core of the state.

For Zimmerman Electric Indy, Central Indiana means the eight counties where our team operates every day:

Electrical Services Available Across All of Central Indiana

No matter which county you call from, you have access to our complete range of residential and commercial electrical services. Here is a breakdown of what we provide throughout the region.

Residential Electrical Services

Our residential electrical services cover the full scope of home electrical work, from simple outlet additions and ceiling fan installation to full-home rewiring, dedicated circuit installation, GFCI outlet upgrades, and indoor and outdoor lighting projects. Most residential calls we receive fall into one of three categories: homeowners dealing with older wiring that has reached the end of its safe service life, renovations or additions that require updated circuits, and new amenities like EV chargers, home theaters, or smart home devices that need new dedicated circuits.

We work in all types of homes across the region, from 1950s bungalows in Broad Ripple that may still have original wiring to brand-new construction in Westfield or McCordsville where the builder left panel capacity for future additions. Whatever the age or style of your home, our team knows how to approach it safely and to current Indiana electrical code.

Electrical Panel Upgrades

Panel upgrades are among the most requested services across all eight counties we serve. The Indianapolis metro has a substantial inventory of homes built between the 1960s and the 1990s, many of which are still running on 100-amp or even 60-amp service. As those homes add central air conditioning, EV chargers, home offices, and modern appliances, original panels reach capacity fast. Our electrical panel upgrade services include 100-to-200 amp upgrades, full fuse-to-breaker conversions, service entrance replacements, and meter base work. We also handle Federal Pacific Stab-Lok and Zinsco panel replacements, both of which are common in older Central Indiana homes and carry documented safety concerns.

EV Charger Installation

Hamilton County has the highest EV ownership rate in Indiana, and demand for Level 2 home charger installation is growing across every county we serve. Our EV charger installation services include hardwired Level 2 charger installation, NEMA 14-50 outlet installation for plug-in chargers, panel assessment and upgrade bundling when needed, and commercial EV station installation for businesses, parking facilities, and fleet operations. We install all major brands including Tesla Wall Connector, ChargePoint, and Clipper Creek.

EV Charger Note for Hamilton County Homeowners

EV charger installation in Carmel, Fishers, Noblesville, and Westfield often requires a panel assessment before installation. Many homes in these communities already have 200-amp service and are ready for a Level 2 charger. Homes in older subdivisions may need a panel upgrade first. When you call us for an EV charger quote, we assess your panel at no charge as part of the estimate process.


Whole-House Surge Protection

Indiana's storm season is real. Summer lightning storms and utility grid switching events send power surges through homes that can silently degrade or instantly destroy electronics, HVAC systems, appliances, and EV chargers. A whole-house surge protector installed at your electrical panel protects everything in the home from surges coming through the utility line, not just the devices plugged into individual power strips. Installation cost in Indianapolis runs between $200 and $600 total, making it one of the best value electrical upgrades a homeowner can make.

Commercial Electrical Services

We serve businesses across all eight counties, from single-location retail shops to multi-tenant commercial buildings, restaurants, warehouses, and office complexes. Our commercial electrical services include new construction rough-in wiring, tenant buildout and renovation electrical, panel service and upgrades, commercial lighting systems, three-phase service installation, and ongoing preventive maintenance contracts. We work with property managers, general contractors, business owners, and facility managers throughout Central Indiana.

County-by-County Electrical Services Breakdown

Each county in our service area has its own character, housing stock, and electrical service needs. Here is what we see most in each of the eight counties and how we address those needs.

Marion County — Indianapolis and Surrounding Communities

Marion County is Indiana's most populous county and encompasses the City of Indianapolis along with communities like Lawrence, Beech Grove, Speedway, and Southport. The county has a wide range of housing stock, from early twentieth century Craftsman bungalows in Broad Ripple and Irvington to mid-century ranches in Southport and more recent builds on the near-northeast side.

The most common electrical issues we address in Marion County include outdated panels in homes built before 1980, aluminum branch circuit wiring from the 1965 to 1973 era, Federal Pacific Stab-Lok panel replacements, and commercial electrical work in the downtown Indianapolis corridor, along with retail and restaurant spaces throughout the county. We also handle a significant volume of residential service upgrades as homeowners add EV chargers and home offices to older homes that were never wired for today's electrical loads.

Hamilton County — Carmel, Fishers, Noblesville, and Westfield

Hamilton County is Indiana's fastest-growing and highest-income county. Carmel, Fishers, Noblesville, and Westfield consistently rank among the best places to live in the state, and new residential construction is a constant presence across the county. Hamilton County also has the highest EV adoption rate in Indiana, which drives significant demand for Level 2 home charger installation.

Our Hamilton County work skews toward premium installations: smart home electrical upgrades, EV charger installation bundled with panel assessments, whole-house surge protection for homes loaded with high-value electronics, and new construction electrical for custom builds throughout the county. Commercial work in Carmel's Arts and Design District and Fishers' Tech District also keeps our commercial team busy.

Hendricks County — Avon, Plainfield, Brownsburg, and Danville

Hendricks County is one of the fastest-growing suburban markets west of Indianapolis. Avon and Brownsburg are seeing rapid residential growth with new subdivisions going up year over year. Plainfield sits along the I-70 corridor and has become a major logistics and light industrial hub. We serve both the residential and commercial sides of this dynamic market.

In Hendricks County, we handle panel upgrades for older ranch homes in established Avon and Brownsburg neighborhoods, new construction electrical for the county's growing residential developments, and commercial electrical work for the warehousing and distribution facilities along the I-70 and Ronald Reagan Parkway corridors.

Boone County — Zionsville, Lebanon, and Whitestown

Boone County is home to some of the most desirable communities in Indiana. Zionsville's historic downtown, excellent school system, and high-income residential market make it a consistent top performer for premium electrical services. Lebanon and Whitestown are growing fast with new development along I-65.

Zionsville homeowners frequently request whole-house surge protection, EV charger installation, and smart panel upgrades as part of broader home renovation projects. Whitestown's new residential construction drives demand for new service installation and panel sizing consultations for future EV charger and home addition loads.

Johnson County — Greenwood, Franklin, and Bargersville

Johnson County is the fastest-growing county south of Indianapolis. Greenwood's US-31 commercial corridor is one of the most active retail and restaurant strips in Central Indiana, and new residential development in Bargersville and Whiteland has accelerated significantly in recent years. Franklin serves as the county seat with a mix of historic homes and growing new construction.

We handle a high volume of EV charger installations in newer Greenwood and Bargersville subdivisions, panel upgrades in older Greenwood and Franklin homes, and commercial electrical work for the US-31 business corridor. Johnson County businesses increasingly ask about commercial EV charging stations as employee and customer amenities.

Morgan County — Martinsville and Mooresville

Morgan County sits southwest of Indianapolis and has a mix of rural properties, agricultural parcels, and suburban communities. Martinsville is the county seat with established neighborhoods and commercial activity along Indiana 37. Mooresville has grown significantly due to its proximity to Hendricks County's development corridor.

In Morgan County, we most commonly work on service upgrades for older rural homes, subpanel installations for detached garages and workshops, generator transfer switch installation, and general residential electrical work in Martinsville and Mooresville. The rural character of much of the county means longer service runs and occasional need for underground conduit for detached structures.

Shelby County — Shelbyville and Surrounding Communities

Shelby County is located east of Marion County along the I-74 corridor. Shelbyville is the county seat and has a mix of manufacturing and residential communities. Morristown and Waldron serve smaller residential markets in the county.

Our Shelby County work includes residential electrical upgrades in older Shelbyville neighborhoods, panel replacements, and commercial electrical for Shelbyville's manufacturing base. We also handle rural property electrical work, including service upgrades and barn and outbuilding wiring throughout the county.

Hancock County — Greenfield and McCordsville

Hancock County is experiencing significant growth, particularly in McCordsville, which has seen some of the fastest residential development in the entire metro area. Greenfield remains the county seat with established neighborhoods and a growing commercial base along the US-40 and I-70 corridors.

In Hancock County, we see strong demand for new construction electrical work in McCordsville's growing subdivisions, panel upgrades in older Greenfield homes, and commercial electrical for the county's I-70 business corridor. New homebuyers in McCordsville frequently ask about future-proofing their panel for EV charger installation.

Why a Local Central Indiana Electrician Beats a National Chain

This is a question we hear from homeowners and business owners who are weighing their options. Why not call the biggest electrical company available? The answer comes down to three things: local knowledge, local accountability, and local investment.

The Local Electrician Advantage

A national chain dispatches technicians who work off national templates. They may not know that Marion County has specific permit requirements that differ from Hamilton County, or that Hendricks County's I-70 commercial corridor operates under a different inspection timeline than residential Avon. They do not know that a neighborhood built in Greenwood in 1968 likely has aluminum branch circuit wiring that requires a specific remediation approach, not a standard replacement.

We do. And that local knowledge speeds up every job, reduces surprises on your invoice, and protects our customers from code violations and failed inspections.


We Know Central Indiana's Permit Requirements

Every municipality in our service area has its own permit office, inspection timeline, and specific code interpretations. Carmel's building department operates differently from Marion County's permit process. Greenwood has specific requirements for commercial buildout permits that differ from Franklin. We have navigated these processes hundreds of times and we handle all permit pulling and inspection scheduling for our customers.

We Know the Housing Stock

Central Indiana's eight-county area has a distinct electrical history. Homes built before 1960 in Marion County neighborhoods often have knob-and-tube wiring or early aluminum service entrances. Homes built between 1965 and 1973 across all eight counties may have aluminum branch circuit wiring, which requires special handling. Homes with Federal Pacific or Zinsco panels, common in 1970s-era Central Indiana construction, require replacement. These are not things you learn from a national training manual. They are things you learn from years of working in these specific neighborhoods.

Accountability Belongs to People, Not Brands

When you call Zimmerman Electric Indy, Zach and Kara Zimmerman's names are on the work. Our 4.8-star Google rating reflects hundreds of real Central Indiana homeowners and business owners who have trusted us with their electrical systems. When something needs attention after a job, we answer the phone and we make it right. That accountability is only possible because we are a local, owner-operated business with a real stake in this community.

 

Why Zimmerman Electric Indy Serves All of Central Indiana

Building an eight-county service area is not the easy path for an electrical contractor. Most small and mid-size contractors concentrate in one or two cities where they can operate efficiently. We made a different decision when we built this company, and it was intentional.

When we looked at the Central Indiana market, we saw a real gap. Homeowners in Shelbyville, Martinsville, and Greenfield were having difficulty finding licensed electricians willing to travel to them. Communities like Bargersville and McCordsville were growing fast but lacked the depth of qualified contractors that Indianapolis proper had access to. Smaller cities in Morgan and Shelby counties were underserved.

We built our team and our logistics to serve the full eight-county area with the same quality and responsiveness we deliver in Indianapolis. There is no geographic surcharge for Morgan County vs. Marion County. Every service area gets the same licensed team, the same workmanship standards, and the same free estimate process.
