You flip a switch and the lights come on. You plug in your phone and it charges. Your AC runs all summer without tripping a breaker every other day.
That’s what happens when your electrical system is built to handle what you’re actually asking it to do. Most homes in Forest Hill are running on panels designed decades ago—back when a household had maybe one TV and a window unit. Now you’ve got smart devices, multiple laptops, gaming systems, and central air pulling power all day long. Your 100-amp panel wasn’t built for that kind of load.
We upgrade panels to 200 amps using NEMA-rated components that meet current code. We replace old wiring that flickers your lights or heats up behind the walls. And if a storm knocks out power, we install whole-house generators that kick on automatically—so your fridge stays cold and your house stays comfortable no matter what’s happening outside.
Carroll Service Co is a family-owned electrical contractor based in Fort Worth. We’ve been serving Forest Hill and the surrounding DFW area since the late ’90s, back when most of these neighborhoods were just getting built.
We’re not a call center. You’re working with licensed Texas electricians who know local code requirements, understand how homes in this area are wired, and show up when we say we will. Our A+ BBB rating and multiple Super Service Awards didn’t come from overselling or disappearing after the job—they came from doing the work right and treating people fairly.
You’ll get upfront pricing before we start. No surprises, no upselling things you don’t need. Just honest electrical work from people who’ve been doing this long enough to know what actually matters.
You call or message us with the issue. We ask a few questions to understand what’s going on—whether it’s a breaker that keeps tripping, outlets that don’t work, or you’re just ready to upgrade your panel before something goes wrong.
We schedule a time that works for you. One of our licensed electricians shows up, evaluates your system, and explains what’s happening in plain terms. No jargon, no runaround. If it’s a simple fix, we handle it same-day in most cases. If it’s a bigger project like a panel upgrade or generator install, we walk you through the scope, timeline, and cost before any work begins.
Once you approve, we pull the necessary permits, complete the work to code, and make sure everything passes inspection. You’re left with an electrical system that works the way it should—and documentation proving it was done right.

We handle everything from small repairs to full system upgrades. That includes panel replacements, circuit additions, outlet and switch installations, recessed lighting, whole-house surge protection, and backup generator installs with automatic transfer switches.
Forest Hill homes—especially those built in the ’80s and ’90s—often need panel upgrades to support modern electrical loads. If your breaker trips when you run the dryer and microwave at the same time, that’s a sign your system is maxed out. We’ll evaluate your current setup, recommend the right amp capacity, and install a new panel that gives you room to grow.
Texas storms are unpredictable. One minute it’s clear, the next you’re dealing with high winds and downed lines. A whole-house generator keeps your HVAC, refrigerator, and essentials running without you lifting a finger. We size the unit based on your home’s load, connect it to your gas line, install the transfer switch, and test everything so it’s ready when you need it.
Every job is done with UL-listed materials, proper permits, and a final inspection. You’re not just getting a quick fix—you’re getting electrical work that lasts and meets the standards insurance companies and future buyers expect.
If your breaker trips regularly, especially when running multiple appliances, that’s the clearest sign your panel is overloaded. Most homes in Forest Hill built before 2000 have 100-amp panels, which were fine back then but struggle with today’s electrical demands.
Other signs include flickering lights, outlets that feel warm to the touch, or a burning smell near your breaker box. Those aren’t things to ignore—they’re fire hazards. If your panel still uses fuses instead of breakers, or if you see rust or corrosion inside the box, it’s time for an upgrade.
We’ll inspect your current system, measure your home’s load, and recommend a panel size that handles what you’re using now plus room for future additions. Most residential upgrades go from 100 amps to 200 amps, which is enough for modern homes with central AC, electric appliances, and charging stations.
A repair fixes a specific issue—a dead outlet, a tripped breaker that won’t reset, or a light fixture that stopped working. Most electrical problems can be solved with a targeted repair, and we’ll always start there if it makes sense.
A full rewire means replacing the wiring throughout your home. That’s usually necessary if your house still has old knob-and-tube wiring, aluminum wiring from the ’70s, or wiring that’s deteriorated to the point where it’s unsafe. You’ll know it’s time if multiple outlets aren’t working, your lights flicker constantly in different rooms, or an inspection flagged your wiring as a hazard.
Rewiring is a bigger project—it involves opening walls, running new wire to code, and updating your panel to handle the new system. But if your home needs it, it’s not optional. Old wiring is one of the leading causes of house fires in Texas, and no amount of small repairs will fix a system that’s fundamentally outdated.
Most whole-house generator installations take one to three days depending on the size of the unit and whether we need to run a new gas line. We start with a site evaluation to figure out the best location—usually on a concrete pad near your gas meter and electrical panel.
Once the generator is in place, we connect it to your home’s gas supply, install an automatic transfer switch inside your electrical panel, and run the wiring between the two. The transfer switch is what allows the generator to kick on within seconds of losing power, so you don’t have to go outside and manually start anything.
After installation, we test the system to make sure it’s switching over correctly and running at the right capacity. We’ll also walk you through basic maintenance—most generators just need an oil change and filter replacement once a year. The whole process includes permits and a final inspection, so everything is documented and up to code.
Some electrical issues can wait until morning. A single outlet that stopped working or a light switch that’s acting up—those aren’t emergencies. But if you’re dealing with sparking outlets, a burning smell, or your main breaker keeps tripping and won’t stay on, that’s a same-day problem.
Electrical fires don’t wait for business hours. If something feels off—especially if you see smoke, smell burning plastic, or notice scorch marks near outlets or your panel—shut off power to that area and call immediately. We offer 24-hour emergency service because we know that electrical problems in Texas heat aren’t just inconvenient, they’re dangerous.
Even if you’re not sure whether it’s urgent, call anyway. We’d rather walk you through it over the phone and tell you it can wait than have you second-guess something that turns into a bigger problem overnight. Most emergency calls we get are situations where waiting would’ve made things worse or more expensive to fix.
Simple repairs—like replacing an outlet, fixing a tripped breaker, or installing a new light fixture—usually start around $100 to $150 depending on what’s involved. That includes the service call, diagnosis, and the actual fix if it’s straightforward.
Bigger projects cost more because they require more time, materials, and permits. A panel upgrade typically runs a few thousand dollars depending on the amp capacity and how much rewiring is needed. Whole-house generator installations vary based on the unit size and whether we’re adding a gas line, but most fall in the range of several thousand dollars once everything’s installed and inspected.
We give you a clear price before we start any work. No hidden fees, no surprises when the job’s done. If we find something during the inspection that changes the scope, we’ll explain what it is, why it matters, and what it’ll cost to fix—then you decide whether to move forward. You’re never locked into anything you didn’t agree to upfront.
Yes. Every electrician on our team is licensed by the Texas Department of Licensing and Regulation, and we carry full general liability insurance. That’s not just a legal requirement—it’s protection for you if something goes wrong during the job.
A licensed electrician knows current NEC codes, understands how to pull permits, and has the training to work safely around high-voltage systems. Unlicensed work might be cheaper upfront, but it won’t pass inspection, it voids most home warranties, and it can make your house harder to sell or insure down the road.
We’ve been doing this for over 25 years in the DFW area. Our licensing, insurance, and BBB rating aren’t just credentials—they’re proof that we’ve been doing electrical work the right way long enough to build a reputation on it. You’re hiring people who know what they’re doing and who’ll be around if you ever need us again.
