D.W. Miller Electrical has been serving Greenville, South Carolina since 2016. What started as a straightforward idea, put licensed electricians to work for neighbors who needed honest, dependable service, has grown into a trusted name across Greenville County. We handle everything from a single tripped breaker to a full-home rewiring, and we work with homeowners, property managers, and business owners alike. Locally owned and operated electricians who know this area, know the housing stock, and show up ready to solve the problem. Dependable service. Honest rates. Local know-how.
Keeping a home safe starts with the wiring behind the walls, and that is where we have focused our work for nearly a decade. The business grew out of a simple conviction: Greenville deserved an electrical contractor that treated every job, large or small, with the same care and attention. We built the company on that idea, and it has guided every service call since.
When you hire local, you hire people who stand behind the job. Our crew knows Greenville County. We know the neighborhoods, the older housing stock in the established districts, and the newer construction spreading through the county. That local knowledge shapes how we approach every estimate and every repair.
We work for homeowners, landlords, property managers, and commercial clients. Whether you need a ceiling fan replaced in a bedroom or a panel upgraded in a commercial suite, we show up on time and ready to wire. Reach out and we'll get it diagnosed.
Seeing flickering lights or a warm outlet? Those are not problems to put off. A flickering light can point to a loose connection, a failing breaker, or a wiring fault deeper in the circuit. A warm outlet is a warning sign that deserves a same-day look. These are the calls we handle every day, and we take each one seriously.
Our electricians diagnose the problem first. We explain what we found, what it will take to fix it, and what it will cost before any work begins. Common repairs we handle include:
We stand behind every circuit we touch. When the repair is done, we test it thoroughly and make sure you understand what was wrong and why it is now right. We'll have your outlets working again in no time.
Most homeowners can't tell a minor wiring issue from a serious one, and that is exactly why a proper diagnosis matters. Older homes throughout Greenville County carry wiring that was never designed for today's electrical loads. Knob-and-tube systems, aluminum branch wiring, and undersized panels are common in the area's established neighborhoods, and they can create real safety and reliability problems as demand grows.
We handle the full range of higher-stakes wiring work:
A workmanship guarantee on every wiring job means you are not left wondering whether the work was done right. We pull the permits, follow the code, and leave the job site clean. Your panel is in good hands with us.
A properly wired home is a safer home, and a lot of what keeps it that way is the everyday work: the outlets that need replacing, the ceiling fan that needs a dedicated run, the outdoor lights that have not worked since last summer. These jobs may seem small, but they add up to a home that functions the way it should.
We install and replace:
Every one of these jobs gets the same attention we bring to a full panel replacement. Pick up the phone and we'll handle the wiring.
More Greenville homeowners are adding electric vehicles, and a Level 2 home charger makes a real difference in daily convenience. A standard 120-volt outlet charges slowly. A dedicated 240-volt circuit, properly sized and installed by licensed electricians, can fully charge most EVs overnight.
We handle the full electrical scope: running the dedicated circuit from your panel, installing the outlet or hardwired charging station, and checking panel capacity before we start. If your current panel cannot carry the added load, we talk through an upgrade before any work begins. We work with Tesla home chargers and all standard EV charging station equipment.
A portable or standby generator is only as safe as the transfer switch behind it. Connecting a generator directly to your home's wiring without a proper transfer switch creates a serious backfeed hazard. We install manual and automatic transfer switches that isolate your home from the utility line, let the generator carry the load safely, and switch back cleanly when power returns.
Whole-home surge protection pairs naturally with generator work. When power comes back on after an outage, the surge that follows can damage appliances and electronics throughout the house. A whole-home surge protector at the panel stops that damage before it starts.
Scheduling an electrician shouldn't be complicated, and for commercial clients it especially should not be. Property managers, office managers, retail operators, and light-industrial contacts all have one thing in common: downtime costs money. We work efficiently, communicate clearly about scope and timing, and do not leave a job half-finished.
Commercial work we handle includes panel upgrades for office and retail spaces, commercial lighting installation and retrofits, outlet and circuit work for expanding offices, and electrical troubleshooting for properties that need a fast diagnosis. We can coordinate around your business hours when scheduling allows. We'll have your space back up and running as quickly as the work allows.
We quote the job before we start it. That means you know the price before any work begins, and you will not find surprise line items on the invoice when we are done. If we open a wall and find something unexpected, we stop, explain what we found, and get your approval before going further.
Same-day service is available when our schedule allows, and we work to accommodate urgent situations quickly. We understand that electrical problems rarely happen at a convenient time, and we are reachable when you need help.
Fair price every visit. On time every visit. Code-compliant every visit.

The table below covers every service we offer, what each one includes, and who it fits best. If you do not see your situation listed, call us and we will point you in the right direction.
| Service | What's Included | Ideal For | Good to Know |
|---|---|---|---|
| Lighting Installation | recessed and ceiling fixture installation, outdoor and security lighting, motion sensor lights, under-cabinet and accent lighting | homeowners updating a room, finishing a basement, or adding outdoor lighting | We can wire a full lighting plan from scratch for remodels and additions, including permit work when required. |
| Breaker & Fuse Repair | breaker replacement, fuse panel assessment, double-tapped breaker correction, AFCI breaker installation | homes with a breaker that will not hold or a fuse panel that needs attention | A breaker that trips repeatedly is often a sign of an overloaded circuit or a wiring fault, not just a worn breaker. |
| Older-Home Rewiring | knob-and-tube wiring replacement, aluminum branch circuit correction, grounding and bonding upgrades, panel capacity evaluation | owners of established Greenville County homes with wiring that has not been updated in decades | Older wiring was not designed for today's loads. We assess what is there, explain what needs to change, and bring it up to current code. |
| Basement & Sump-Pump Circuits | dedicated sump-pump circuit, basement outlet and lighting wiring, GFCI protection in wet areas | homeowners finishing a basement or adding a sump pump that needs its own protected circuit | A sump pump on a shared circuit can lose power at the worst moment. A dedicated circuit keeps it running independently. |
| EV Charger Installation | Level 2 charger wiring, dedicated 240-volt circuit, panel capacity check, permit coordination | homeowners who want faster, code-compliant EV charging at home | Most Level 2 charger installations require a dedicated 50-amp circuit and a permit. We handle both from start to finish. |
| Wiring & Rewiring | whole-home rewiring, knob-and-tube replacement, aluminum branch circuit wiring correction, targeted old-wiring updates | older homes with wiring that was not designed for today's electrical demand | We bring affected circuits up to current code and document what was replaced so you have a clear record for insurance or resale. |
| Dedicated Appliance Circuits | dryer and range circuits, refrigerator and dishwasher circuits, workshop and garage circuits, 240-volt circuit installation | homeowners adding a major appliance or a workshop that needs its own protected circuit | Major appliances that share a circuit with other loads are more likely to trip breakers. A dedicated circuit solves that reliably. |
| Whole-Home Surge Protection | panel-level surge protector installation, grounding and bonding check, protection for appliances and electronics | any home in South Carolina's storm season where lightning and grid fluctuations are a real risk | Panel-level surge protection intercepts voltage spikes before they reach your circuits. It is one of the most cost-effective upgrades we install. |
| Ceiling Fan Installation | fan installation and replacement, new circuit or switched outlet where needed, wiring in any room type | any room that needs a ceiling fan added, replaced, or properly wired for the first time | Rooms without an existing ceiling box or switched outlet may need a new circuit. We handle that as part of the installation. |
| Wiring for Additions & Remodels | new room circuit installation, kitchen and bathroom wiring, subpanel addition for added load, permit and inspection coordination | homeowners finishing a basement, adding a room, or remodeling a kitchen or bathroom | We do a load calculation before we start so you know exactly what your panel can carry and whether an upgrade is needed. |
| Electrical Repairs & Troubleshooting | dead outlets and switches, breakers that trip repeatedly, flickering or dimming lights, tracing wiring faults to the source | any homeowner or business with an electrical problem that needs a diagnosis | We troubleshoot the cause, not just the symptom. If a breaker keeps tripping, we find out why before resetting it. |
| Electrical Panel UpgradesMost Popular | 200-amp panel upgrades, main panel replacement, service entrance upgrades, subpanel installation | homes with a 60- or 100-amp panel that can no longer carry modern electrical loads | Panel upgrades require a permit and inspection. We handle both, and we walk you through the safety case before any work begins. |
| Outlet & Switch Installation | new outlet installation, GFCI outlet upgrades, outdoor and weatherproof outlets, switch replacement and wiring | homeowners adding outlets, upgrading to GFCI, or replacing switches that stopped responding | GFCI protection is required by code in kitchens, bathrooms, garages, and outdoor areas. We install and test them to spec. |
| Electrical Safety Inspections | full home wiring assessment, pre-sale and pre-purchase inspections, home inspector finding resolution, written documentation of findings | homeowners listing a property, buyers before closing, or anyone who received a concern from a home inspector | Common findings include missing GFCI protection, double-tapped breakers, and outdated wiring. We document what we find and handle the repair work. |
| Backup Generator Installation | transfer switch installation, dedicated generator circuit, panel capacity assessment, portable and standby hookups | Greenville homeowners who want reliable backup power during summer storms or winter ice events | We handle the electrical side only: the transfer switch, the circuit, and the panel load assessment. The generator is ready when the power goes out. |
How do I know if my electrical panel needs to be upgraded?
A few signs point to a panel that is running out of capacity: breakers that trip often under normal use, a panel rated at 60 or 100 amps in a home with modern appliances, a fuse box that was never converted to breakers, or a home inspector who flagged the panel on a recent report. If you are adding an EV charger, a hot tub, or a major appliance and the panel is already close to capacity, an upgrade is worth discussing before the work begins. Call us and we will assess what you have.
Why does my breaker keep tripping?
Repeated tripping usually means one of three things: the circuit is overloaded with more draw than it was designed to carry, there is a wiring fault somewhere on the circuit, or the breaker itself has worn out and is no longer holding correctly. Resetting it without finding the cause just delays the problem. We trace the circuit, find out what is actually happening, and fix it at the source.
Is the electrical work permitted and inspected?
Yes. Jobs that require a permit under South Carolina's electrical code, such as panel upgrades, new circuit installation, and EV charger hookups, are pulled and inspected as a standard part of the job. We handle the permit application and coordinate the inspection. You get a code-compliant installation with a record of the inspection on file.
Same-Day and Emergency Availability
We offer same-day scheduling for most jobs and emergency service when the situation cannot wait. We are available every day from 8:00 AM to 9:30 PM, including weekends.
What do flickering or dimming lights usually mean?
Occasional flickering when a large appliance starts up can be normal, but persistent flickering or lights that dim without explanation often point to a loose connection, an overloaded circuit, or a wiring problem. Flickering that affects multiple rooms or the whole house may indicate a utility issue or a problem at the service entrance. Either way, it is worth having us look at it before the underlying cause gets worse.
Is it safe to have aluminum or knob-and-tube wiring in an older home?
Knob-and-tube wiring and aluminum branch circuit wiring are not automatically dangerous, but both carry risks that modern wiring does not. Knob-and-tube was not designed for today's electrical loads and lacks a ground wire. Aluminum branch circuit wiring can loosen at connections over time and create a fire hazard if not maintained or updated. We assess what is in your home, explain what the actual risk level is, and give you honest options for addressing it.
What does a whole-home surge protector actually do?
A plug-in surge strip protects the single outlet it is plugged into. A panel-level surge protector intercepts voltage spikes at the main panel before they can travel through your circuits and reach your appliances, electronics, and wiring. In South Carolina, where summer storms and lightning strikes are common, panel-level protection covers the whole house in a way that individual strips cannot. We install it at the panel and pair it with proper grounding for complete coverage.
Work Performed by Licensed Electricians
Every job we take on is performed by licensed electricians who know the local code requirements and handle permit work as a standard part of the process.
What does EV charger installation involve?
A Level 2 home charger requires a dedicated 240-volt circuit, typically a 50-amp circuit run from your main panel to the garage or driveway location where you want the charger mounted. We check your panel capacity first to make sure it can carry the added load, pull the required permit, run the circuit, and wire the charger. The whole job usually takes a few hours once the permit is in hand.
Do I need to be home while the work is being done?
For most jobs, yes. We review the scope and pricing with you before anything begins, and we walk you through what was done when we finish. If access to specific areas of the home is needed, such as the panel, attic, or crawl space, someone should be available to let us in and answer questions if something unexpected comes up. For commercial jobs, a property manager or authorized contact on site works fine.
Workmanship We Stand Behind
We back every wiring job with a workmanship guarantee and give you an honest assessment of what the work involves before anything begins.
How does pricing and the estimate process work?
We go over the scope of work with you before any work begins and give you a clear price. If we open a wall or access a panel and find something unexpected, we stop, explain what we found, and get your approval before continuing. You always know the cost before we proceed. Permit fees, when required, are part of the job and not a surprise line item at the end.
Do you offer same-day or emergency electrical service?
Same-day availability is offered for most jobs. When the situation cannot wait, we provide emergency service as well. We operate every day from 8:00 AM to 9:30 PM, including weekends, so you can reach us well into the evening when something urgent comes up. Call (864) 365-3623 and we will let you know how quickly we can get to you.
How do I know if my home is ready for added electrical load?
The short answer is a load calculation. We look at what your panel is rated for, what is already drawing from it, and what the new load will add. If you are adding an EV charger, a hot tub, a major appliance, or finishing a basement with new circuits, we run those numbers before we start so there are no surprises. Sometimes the existing panel can carry it. Sometimes a subpanel or a full upgrade is the right move. We explain the options and let you decide.
Every electrical situation is a little different. Call (864) 365-3623 and we will talk through what you are dealing with and give you a straight answer on what it takes to fix it.
