Whether you are dealing with a tripped breaker at midnight, planning a full panel upgrade, or need a licensed electrician near you for everyday repairs and installations, we handle it all for residential and commercial customers throughout Greenville County. We offer same-day availability for most jobs and emergency service when the situation can't wait. Call (864) 365-3623 for a quote and let's get your electrical work scheduled.
Seeing flickering lights or a warm outlet? Those symptoms can point to anything from a loose connection to a wiring fault, and most homeowners can't tell a minor wiring issue from a serious one without a trained eye on it. We do. Our team handles the full range of common electrical problems: dead outlets, switches that stopped responding, breakers that trip repeatedly, and lights that flicker or dim without explanation.
We troubleshoot the cause, not just the symptom. If your outlet has stopped working, we'll trace it back to the source. If your breaker keeps tripping, we'll find out why instead of just resetting it. We also install GFCI outlets and AFCI breakers during repair visits, so a service call often doubles as a safety upgrade for the affected circuit.
We stand behind every circuit we touch, and that commitment starts with an honest diagnosis before any work begins. Reach out and we'll get it diagnosed.
A properly wired home is a safer home, and the everyday installation work we do makes a real difference in how a space functions. For outlets and switches, we install new outlets throughout the home, add outdoor and weatherproof outlets, wire garage circuits, and upgrade to GFCI outlets wherever code requires them. Every installation is code-compliant, and we handle permit work when the job calls for it.
For lighting, we install recessed lighting, ceiling fixtures, outdoor and security lighting, motion sensor lights, and under-cabinet lighting. If you are finishing a basement or updating a kitchen, we can wire the whole lighting plan from scratch.
Ceiling fan installation is one of our most common calls. We install, replace, and wire ceiling fans in any room, including rooms that need a new circuit or a switched outlet added to support the fan. We show up on time and ready to wire, every time. We'll have your outlets working again in no time.
Keeping a home safe starts with the wiring behind the walls, and older homes in Greenville County sometimes carry wiring that was never designed for today's electrical demand. Knob-and-tube wiring, aluminum branch circuit wiring, and undersized circuits are all safety concerns we address regularly. We perform whole-home rewiring and targeted old-wiring replacement, bringing the affected circuits up to current code.
For homeowners adding a room, finishing a basement, or upgrading a kitchen or bathroom, we handle the electrical side of the project from start to finish. That includes new circuit installation, subpanel installation when the existing panel needs help carrying the added load, and dedicated circuits for dryers, ranges, refrigerators, and other major appliances that need their own protected circuit.
When you hire local, you hire people who stand behind the job. We do load calculations before we start so you know exactly what your home can carry and what it needs. Pick up the phone and we'll handle the wiring.
Greenville's mix of hot, humid summers, occasional winter storms, and a fast-growing housing stock creates specific electrical demands. The four-season climate means heating and cooling systems run hard all year, and severe thunderstorms, tornadoes, and the occasional ice storm make backup power and surge protection genuinely worthwhile investments here. The following services come up again and again for that reason.
Older homes throughout Greenville County were built with panels sized for far lighter electrical loads than today's households demand. A 60-amp or 100-amp panel that served a home adequately decades ago struggles to keep up with modern appliances, home offices, EV chargers, and HVAC loads. We perform 200-amp panel upgrades, main panel replacements, and service entrance upgrades, and we walk you through the safety case for replacing outdated equipment before it causes a problem. A workmanship guarantee on every wiring job means you can count on the installation long after we leave.
Summer storms and ice events can knock out power for hours or days at a stretch. We handle the electrical side of generator hookups: the transfer switch installation, the dedicated circuit that feeds the generator, and the panel capacity assessment to make sure your system can carry the load. Whether you are connecting a portable generator or a standby unit, we wire it correctly and safely so it's ready when you need it.
South Carolina's storm season brings lightning strikes and grid fluctuations that can damage appliances, electronics, and wiring in seconds. Panel-level surge protection is a different category from the plug-in strips most people are familiar with. A whole-home surge protector installed at the panel intercepts voltage spikes before they reach your circuits, and we pair it with proper grounding and bonding to give your home a complete layer of protection. It is one of the most cost-effective electrical upgrades available for the level of protection it provides.
Scheduling an electrician shouldn't be complicated, especially for specialty work that requires both the right equipment and the right permit. We install Level 2 EV chargers for homeowners who want faster, more reliable charging at home. That includes the dedicated 240-volt circuit, the panel capacity check, and the charger wiring itself. We coordinate permit work so the installation meets local code.
Beyond EV chargers, we handle hot tub and spa electrical hookups, pool electrical wiring, bathroom exhaust fan wiring, and hard-wired smoke detector installation. These are jobs that require a proper dedicated circuit and code-compliant connections, and we treat each one with the same attention we bring to any other service call. Your panel is in good hands with us.
Property managers, business owners, and contractors in the Greenville area need a commercial electrician who shows up prepared and finishes the job on schedule. We work with commercial clients on electrical repair, panel upgrades, commercial lighting installation, and electrical work for office and retail buildouts. We also take on new construction and renovation projects where a reliable electrical contractor is part of the project team from the start.
All commercial work is performed by licensed electricians, and we handle permit applications and code-compliant installations as a standard part of the job, not an add-on. Locally owned and operated electricians who understand the local inspection process make a difference when a project is on a deadline.
Most homeowners can't tell a minor wiring issue from a serious one, and that uncertainty becomes urgent when a home is going on the market or a buyer's inspector flags the electrical system. We perform electrical safety inspections for homeowners preparing to list, buyers who want a full picture before closing, and anyone who received a concern from a home inspector and needs it resolved.
Common inspection findings we address include missing GFCI protection in kitchens and bathrooms, outdated wiring, double-tapped breakers, and the absence of AFCI protection on bedroom circuits. We document what we find, explain what needs to be corrected, and handle the repair work so the inspection report doesn't stall your closing. We'll have your outlets working again in no time.
D.W. Miller Electrical has been serving Greenville and the surrounding Upstate South Carolina area since 2016. We are locally owned and operated electricians who live in this community and take our reputation in it seriously. That means transparent pricing before work begins, honest answers about what a job actually requires, and a commitment to finishing what we started.
We keep our pricing straightforward and our schedules reliable. When we say we'll be there, we show up. When we say the work is done, it's done right.
Fair price every visit. On time every visit. Code-compliant every visit.
We are based in Greenville and travel throughout Greenville County and the broader Upstate South Carolina region for both residential and commercial electrical work. Communities we regularly serve include:
If you are nearby and need an electrician, give us a call. We make the trip.
Yes. When you call (864) 365-3623, you reach a local person who knows Greenville County and can speak to your situation directly. We are locally owned and operated, and the people answering the phone are the same people scheduling the work.
We work with homeowners, landlords, property managers, and commercial clients throughout Greenville County. Whether you need a ceiling fan replaced in a bedroom or a panel upgrade in a commercial suite, we handle it. The same standard of work applies to every job regardless of the property type.
Same-day availability is offered for most jobs, and we provide emergency service when the situation cannot wait. Our hours run every day from 8:00 AM to 9:30 PM, 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.
First, check your main breaker panel to see if a breaker has tripped or if the main breaker has shut off. If the breakers look normal but power is still out in part of the home, the issue may be in the wiring or at the service entrance, and that warrants a call to an electrician. Do not attempt to open the panel or probe wiring yourself. Call us and we will diagnose it safely.
Yes, we operate every day of the week from 8:00 AM to 9:30 PM, including Saturdays and Sundays. Electrical problems do not follow a Monday through Friday schedule, and we make ourselves available accordingly. Call (864) 365-3623 to check availability and get on the schedule.
The main factors are the scope of work, the age and condition of the existing wiring, and whether permit work is required. A straightforward outlet replacement costs far less than a panel upgrade or whole-home rewiring. If we open a wall and find something unexpected, we stop, explain what we found, and get your approval before continuing. You always know the cost before the work proceeds.
Our quote covers the labor and materials for the agreed scope of work. Permit fees, when required, are part of the job and not a surprise add-on. We walk through the pricing with you before any work begins so there are no unexpected line items on the invoice when we are done.
Yes, and we do it regularly throughout Greenville County. Older homes in established neighborhoods often carry knob-and-tube wiring, aluminum branch circuit wiring, or undersized panels that were never designed for today's electrical demand. We assess what is there, explain what needs to be corrected, and handle the repair or replacement work to bring the affected circuits up to current code.
Clear reasonable access to the areas where work will be done, including the breaker panel, the outlets or fixtures involved, and any wall space that may need to be opened. If you have pets, securing them before we arrive helps the visit go smoothly. Beyond that, there is not much preparation required on your end.
We start by reviewing the job with you and confirming the scope of work and pricing before anything begins. Then we assess the specific area or circuit involved, diagnose the problem if it is a repair call, and get to work. We test everything before we leave and walk you through what was done.
Whether you need a same-day repair, a panel upgrade, or a full rewiring project, D.W. Miller Electrical is ready to help. We offer same-day availability for most jobs and emergency service when you can't afford to wait. Our team serves homeowners, landlords, property managers, and businesses throughout Greenville County with the same dependable standard of work on every call.

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.
