Your breaker stops tripping every time you run the dryer and microwave at once. Your panel can handle the load your home actually needs—not what it had 30 years ago.
You’re not dealing with flickering lights, warm outlets, or that nagging worry about whether your electrical system is safe. You’ve got whole-house surge protection, so a lightning strike doesn’t fry your HVAC, your appliances, and everything plugged into the wall.
If the power goes out during the next storm, your generator kicks on automatically. Your fridge stays cold. Your family stays comfortable. And you’re not scrambling to find an electric repair company in Tarrant County at 9 p.m. on a Saturday because something finally gave out.
Carroll Service Co has been serving Tarrant County for over 25 years. We’ve seen the DFW area grow, watched neighborhoods expand, and worked in homes built in every decade from the 1950s to last year.
We know the pier and beam foundations. We know the older panels that need upgrading. We know Oncor’s requirements and Fort Worth’s codes, and we pull permits the right way every time. A+ BBB rating. Multiple Super Service Awards. Fully licensed and insured.
We’re not a call center dispatching the cheapest guy available. We’re a family-owned electrical company in Tarrant County, and the people who answer the phone are the same ones who show up to do the work.
You call or fill out the form. We schedule a time that works for you—not just whenever we feel like showing up. If it’s an emergency, we’re available 24/7.
We come out, assess what’s going on, and give you transparent pricing before we start. No surprise fees. No hidden permit costs or inspection charges that show up later. You know what you’re paying and why.
Then we do the work. We pull the permits. We use commercial-grade materials and UL-listed components that last. When we’re done, the system is inspected, code-compliant, and safe. You get documentation for everything—permits, inspections, warranties.
If it’s a panel upgrade, we coordinate with Oncor. If it’s a generator install, we handle the gas line, the transfer switch, and the startup. You don’t have to call three different contractors or figure out who’s responsible for what.
Ready to get started?
Panel upgrades from 100-amp to 200-amp service, because your home’s electrical load isn’t what it was in 1985. Whole-house surge protection—critical in Tarrant County where we average over 50 thunderstorm days a year and sit in one of Texas’s most active lightning corridors.
Generator installations with automatic transfer switches, so you’re not outside in the rain flipping breakers when the power cuts out. Emergency electrical repairs when something fails and you need someone who actually answers the phone after 5 p.m.
Wiring services for additions, remodels, or older homes where the wiring is cloth-covered and failing. Recessed lighting. EV charger installations. Safety inspections that catch problems before they become fires or insurance claims.
Every job includes permit pulling, code compliance, and inspection coordination. We don’t skip steps. We don’t use residential-grade parts on jobs that need commercial-grade components. And we don’t leave until the work is done right.
If your home was built before 1990 and still has a 100-amp panel, you’re probably pushing it too hard. Modern homes use significantly more power than they did 30 years ago—think central air, multiple computers, phone chargers, big-screen TVs, kitchen appliances that all run at once.
A 100-amp panel wasn’t designed for that load. You’ll notice breakers tripping frequently, lights dimming when the AC kicks on, or outlets that feel warm to the touch. Those are signs your system is overloaded.
Upgrading to a 200-amp panel isn’t just about convenience. It’s about safety. Overloaded panels are a fire risk. And if you’re planning to sell your home, buyers and inspectors will flag an outdated panel. Most insurance companies won’t even cover surge damage if your system isn’t up to code. The upgrade pays for itself in safety, functionality, and resale value.
Fort Worth requires permits for most electrical work beyond simple fixture replacements. The permit itself typically runs $50 to $150 depending on the scope of work. Inspection fees are usually around $75.
If you’re doing a panel upgrade or generator installation, you’ll also have utility connection fees when Oncor comes out to disconnect and reconnect service. That’s another $100 to $200, depending on timing and complexity.
Here’s the thing: a lot of contractors don’t mention these costs upfront. They give you a price for labor and materials, then hit you with permit and inspection fees after the fact. We include everything in the estimate so there’s no surprise when the bill comes. You know what you’re paying before we start, and that includes permits, inspections, and any utility coordination fees that apply to your job.
Power strips with surge protection only cover what’s plugged into them—and most of them are cheap, wear out over time, and don’t actually stop a serious surge. A direct lightning strike or a major power surge from the grid will blow right through a $15 power strip.
Whole-house surge protection installs at your main panel and protects everything in your home—HVAC system, appliances, electronics, anything hardwired or plugged in. Tarrant County sees over 50 thunderstorm days a year, and we’re in one of the most active lightning corridors in Texas. Surge damage is common here.
Most homeowners insurance policies don’t cover power surge damage unless you can prove the surge came from outside your home—and even then, coverage is limited. A whole-house surge protector costs a few hundred dollars to install and can save you thousands in replacement costs when the next storm rolls through. It’s also required by the 2020 National Electrical Code for all new dwelling unit services, so it’s becoming standard anyway.
For emergency work, we’re available 24/7. If your power’s out, you’ve got sparking outlets, or something’s creating an immediate safety risk, we’ll get someone to you as fast as possible—usually within a few hours.
For scheduled work like panel upgrades, generator installs, or rewiring projects, we’re typically booking 2 to 4 weeks out. That’s normal for reputable electrical contractors in Tarrant County. If someone can start tomorrow, it usually means they’re either desperate for work or they’re cutting corners somewhere.
We’d rather be honest about timing than overpromise and underdeliver. When we give you a date, we show up. And if something changes, we’ll let you know ahead of time—not the morning of your appointment. You’re not sitting around wondering if we’re coming or rearranging your schedule because we didn’t communicate.
The generator produces the power. The transfer switch is what safely connects that power to your home’s electrical system. You can’t run a backup generator without a transfer switch—or at least, you can’t do it safely or legally.
When the power goes out, the transfer switch detects the outage and automatically disconnects your home from the utility grid. Then it connects your home to the generator. When utility power comes back, it switches everything back and shuts the generator down. This all happens in seconds, and you don’t have to do anything.
Without a transfer switch, you’d be running extension cords from a portable generator or risking backfeeding power into the grid—which is illegal, dangerous, and can kill a lineman working to restore power. A properly installed standby generator with an automatic transfer switch is the only way to safely power your whole home during an outage. We handle the generator, the transfer switch, the gas line connection, and the startup, so everything works the way it’s supposed to when you actually need it.
Yes. A lot of older homes in Tarrant County still have knob-and-tube wiring, cloth-covered wiring, or aluminum wiring from the 1960s and 70s. These systems weren’t designed for modern electrical loads, and they’re often deteriorating or improperly modified by previous owners.
We’ll assess what you’ve got, tell you what’s safe and what’s not, and give you a realistic plan for upgrading or replacing it. Sometimes that means rewiring the whole house. Sometimes it means addressing the most critical areas first and phasing the rest over time.
We’ve worked on homes built in every decade from the 1950s to now. We know pier and beam foundations. We know how to fish wire through old plaster walls without tearing everything apart. And we know how to bring an outdated system up to code without making it a bigger project than it needs to be. If your home’s wiring is old and you’re not sure what shape it’s in, we’ll give you a straight answer about what needs to happen and why.
