Your lights stop flickering when the AC kicks on. Your breaker quits tripping every time you run the microwave and coffee maker at the same time. You plug in what you need, when you need it, without wondering if something’s about to short out.
Most homes in Southlake built before 2000 are running on 100-amp panels that weren’t designed for today’s load. You’ve added smart thermostats, multiple TVs, home offices, kitchen appliances that pull serious power—and your electrical system is struggling to keep up. That’s not a “maybe someday” problem when you’re dealing with a panel that heats up or circuits that trip during a summer heat wave.
A home electrician in Southlake, TX handles the full scope: troubleshooting what’s actually wrong, upgrading your panel to handle modern demand, installing dedicated circuits where you need them, and making sure your family isn’t dealing with fire hazards hiding behind your walls. You get a system that works the way you live now—not the way someone lived in 1995.
Carroll Service Co has been handling home electrical repair and installation services in Southlake since 1998. We’re not a franchise. We’re a family-owned electrical contractor that earned an A+ BBB rating by showing up when we say we will and doing the work right the first time.
Every electrician on our team carries full Texas licensing and insurance. We’ve seen what happens when shortcuts get taken—panels installed wrong, wiring that doesn’t meet code, repairs that create bigger problems six months later. That’s not how we operate.
Southlake homeowners call us when they need panel upgrades for EV chargers, when their breaker box is outdated and dangerous, or when they’re buying a home and want an honest assessment before closing. We’ve worked in nearly every neighborhood here—Timarron, Carillon, Southlake Estates—and we know the common issues these homes face as they age.
You call or submit a request online. We schedule a time that actually works for your schedule—not a four-hour window where you’re stuck waiting around. Our electrician shows up on time, walks through what you’re dealing with, and runs a full diagnostic if needed.
Before any work starts, you get upfront pricing. No “we’ll see once we get in there” nonsense. You know what the job costs, what it includes, and how long it takes. If we find something else that needs attention—like outdated wiring or a panel that’s unsafe—we’ll tell you what it is, why it matters, and what it costs to fix. You decide what happens next.
Once you approve the work, we handle permits, pull the right materials, and complete the installation or repair according to Texas electrical code. Most electrical troubleshooting for homes in Southlake gets wrapped up the same day. Larger jobs like panel upgrades or whole-home rewiring get scheduled in stages if that makes more sense for your timeline.
When we’re done, the system gets tested, you get a walkthrough of what we did, and everything comes with a warranty that covers parts and labor. If something doesn’t work right, we come back and make it right.

Panel upgrades are the most common request we get. Your home might be running on a 100-amp or 150-amp panel that can’t support your HVAC system, electric range, EV charger, and everything else you’re plugging in. We install 200-amp panels with room to expand, using commercial-grade components that last decades longer than builder-grade equipment.
Electrical troubleshooting covers the issues you notice but can’t pinpoint—outlets that don’t work, lights that dim randomly, breakers that trip without obvious cause. We trace the problem back to the source, whether that’s faulty wiring, an overloaded circuit, or a connection that’s deteriorating. You’re not paying for guesswork.
Home wiring installation comes up during remodels, additions, or when you’re adding new equipment that needs dedicated circuits. We run new wiring to code, install the outlets or hardwired connections you need, and make sure your electrical load is distributed properly. Southlake homes—especially in older neighborhoods—often need rewiring in sections where the original install is failing or wasn’t done right to begin with.
Surge protection, generator hookups, EV charger installations, recessed lighting, and safety inspections round out the list. If it’s electrical and it’s in your home, we handle it. And because Southlake sits in an area where summer storms and winter freezes knock out power regularly, generator installations have become one of the most requested services we offer.
Your breakers trip frequently, even when you’re not running anything unusual. Your lights flicker when the AC or another large appliance kicks on. You see scorch marks, smell burning plastic, or notice the panel feels warm to the touch. These are all signs your panel is overloaded or failing.
Most homes in Southlake built before 2000 have 100-amp or 150-amp panels. That was fine when homes had fewer electronics, smaller HVAC systems, and no EV chargers. Now you’re pulling more power than the system was designed to handle. If you’re adding any major appliance—EV charger, hot tub, pool equipment, backup generator—you’ll likely need a 200-amp panel to support it safely.
Another indicator: your home inspector flagged the panel during a real estate transaction. Federal Pacific, Zinsco, and some older Square D panels are known fire hazards. If you have one of those, upgrading isn’t optional—it’s a safety issue. We replace outdated panels with modern, code-compliant equipment that gives you room to expand without maxing out your capacity.
We start by asking what you’ve noticed—when the problem happens, what else is running at the time, whether it’s isolated to one area or affecting multiple rooms. Then we test the circuits, check voltage at outlets, inspect your panel for loose connections or signs of overheating, and trace wiring paths to find where the issue originates.
A lot of electrical problems in Southlake homes come from aluminum wiring installed in the 1960s and 70s, backstabbed outlets that have loosened over time, or circuits that were daisy-chained incorrectly during a DIY project. We use diagnostic tools to measure current draw, identify shorts, and locate breaks in wiring that aren’t visible. You’re not paying us to guess—we find the actual source.
Once we identify the problem, we explain what’s wrong, what caused it, and what it takes to fix it permanently. Sometimes it’s a simple repair—replacing a faulty outlet or tightening a connection. Other times it means rewiring a section of your home or splitting an overloaded circuit into two dedicated lines. Either way, you know what you’re paying for before we start the work.
Most service calls for basic repairs or troubleshooting take two to four hours. That includes diagnosing the issue, pulling the right materials from our truck, completing the repair, and testing everything to make sure it works. If we need a part that’s not standard stock, we’ll let you know upfront and schedule a follow-up.
Panel upgrades take longer—usually a full day, sometimes two depending on the scope. We’re pulling permits, shutting off power to your home, removing the old panel, installing the new one, reconnecting all your circuits, and coordinating with Oncor to reconnect service. You’ll be without power for a few hours during the switchover, but we schedule that during a time that works for you and we move fast.
Larger jobs like whole-home rewiring, generator installations, or adding multiple circuits during a remodel get broken into phases. We’ll give you a timeline before we start so you know what to expect. The key is we don’t drag things out—we show up, do the work, and get your power back on as quickly as possible without cutting corners.
Yes. If your power is out, your panel is sparking, or you’re dealing with an electrical fire hazard, call us. We respond to emergency calls 24/7 because electrical emergencies don’t wait for business hours.
Most emergency calls in Southlake involve storm damage, panels that have failed suddenly, or situations where a homeowner notices smoke or burning smells coming from outlets or the breaker box. We’ll walk you through what to do immediately—usually that means shutting off power at the main breaker if it’s safe to do so—and then we get someone to your home as fast as possible.
Emergency service costs more than scheduled work because we’re pulling a licensed electrician off-hours and prioritizing your call over everything else. But if you’re dealing with a legitimate safety issue, that’s not the time to wait until Monday morning. We’ll stabilize the situation, make sure your home is safe, and then schedule any follow-up work that needs to happen once the immediate danger is handled.
Service calls for basic troubleshooting and repairs typically run $200 to $500 depending on what’s involved. That covers diagnosing the issue, making the repair, and testing the system. If you need parts that aren’t standard stock, that gets added to the total, but we tell you the cost before we order anything.
Panel upgrades range from $2,500 to $5,000 for most homes. That includes the new panel, labor, permits, and inspection. If your home needs additional work—like updating the meter base, running a new service line, or rewiring sections that don’t meet code—that adds to the cost. We give you a detailed estimate before we start so there’s no confusion about what you’re paying for.
Generator installations, whole-home rewiring, and large-scale projects get priced individually based on your home’s size, the scope of work, and what equipment you’re installing. We’re not the cheapest option in Southlake, and that’s intentional. You’re paying for licensed electricians, commercial-grade materials, and work that passes inspection the first time. Cheap electrical work ends up costing more when it fails or creates safety issues down the line.
Every electrician we send to your home carries a current Texas electrical license and full liability insurance. That’s not negotiable. It protects you if something goes wrong, and it ensures the person working on your electrical system actually knows what they’re doing.
Texas requires electricians to complete thousands of hours of training and pass a state exam before they can work independently. A licensed electrician understands code requirements, knows how to install equipment safely, and can pull permits for work that requires inspection. If someone shows up without a license, they’re not qualified to touch your electrical system—period.
Insurance matters just as much. If an unlicensed or uninsured contractor damages your property or gets injured on the job, you’re liable. Our insurance covers property damage, injuries, and any issues that arise during the course of work. You can ask to see proof of licensing and insurance before we start—we’ll show you without hesitation. That’s standard practice for any legitimate electrical contractor in Southlake, TX.
