Most electrical problems don’t announce themselves until something stops working or starts sparking. By then, you’re dealing with a safety issue, not just an inconvenience.
When your electrical system is working the way it should, you don’t think about it. Lights flip on. Appliances run. Your panel handles the load without tripping breakers every time you run the microwave and the AC at the same time.
That’s what proper electrical work gets you. No burning smells. No flickering lights when the dishwasher kicks on. No wondering if that outlet in the garage is actually safe to use. Just a system that does its job so you can do yours.
Carroll Service Co has been handling electrical work in the Fort Worth and Mid-Cities areas for over 25 years. We’re a family-owned electrical contractor, which means when you call, you’re talking to people who actually care about the outcome.
Every electrician on our team is fully licensed and insured. We hold an A+ rating with the Better Business Bureau and multiple Super Service Awards from Angie’s List because we show up, do the work right, and don’t cut corners.
Denton County homes deal with aging electrical systems that weren’t built for today’s loads. Most homes built before 2000 have 100-amp panels that struggle when you’re running central air, multiple appliances, and charging devices all at once. We’ve upgraded hundreds of these systems and know exactly what your home needs to handle modern electrical demands safely.
You call or reach out online. We schedule a time that works for you, usually within a day or two. For emergencies, we move faster.
When we arrive, we assess the situation and explain what’s going on in plain language. No jargon. No upselling. Just a clear explanation of the problem and what it takes to fix it. You get transparent pricing before any work starts.
Once you approve, we handle the repair or installation with the right materials and code-compliant methods. Our trucks are fully stocked, so we’re not making multiple trips for parts. Most jobs get completed the same day.
After the work is done, we test everything to make sure it’s functioning properly. You get a detailed warranty on parts and labor. If something doesn’t seem right later, you call us back and we make it right.

We handle the full range of electrical work for homes and businesses in Denton County. That includes troubleshooting and repairs when something’s not working, panel upgrades when your system can’t keep up, and installations for everything from recessed lighting to whole-house surge protection.
If you’re adding an EV charging station, we install those too. Electric vehicle adoption jumped 20% in 2024, and most homes need dedicated circuits to handle the load. We make sure your electrical system can support it without overloading your panel.
Generator installations are another common request, especially after ice storms and severe weather knock out power across the region. We install backup generators that kick on automatically when the grid goes down, so your essentials keep running.
All our work follows current National Electrical Code standards and local building requirements. We pull the necessary permits and handle inspections. That matters when you sell your home or file an insurance claim. Unpermitted electrical work creates problems down the line, and we don’t leave you with that headache.
Panel upgrades in Denton County typically run between $1,800 and $3,200, depending on the size of the panel and whether your home needs additional wiring or service line upgrades. Most homes moving from a 100-amp to a 200-amp panel fall somewhere in the middle of that range.
The price includes the panel itself, labor, permits, and inspection fees. If your home has aluminum wiring or outdated components that need replacing at the same time, that adds to the total. We give you a clear estimate upfront so there’s no confusion about what you’re paying for.
Upgrading your panel isn’t just about adding capacity. It’s about safety. Older panels with worn breakers or outdated designs can overheat or fail to trip when they should. That’s a fire risk. A modern panel with proper circuit protection handles today’s electrical loads without putting your home at risk.
Yes. Texas requires anyone doing electrical work to hold a valid electrical license. That’s not just a formality. Licensed electricians have the training and knowledge to do the work safely and according to code.
Unlicensed work creates serious problems. If something goes wrong, your homeowner’s insurance may not cover the damage. If you try to sell your home, unpermitted electrical work can kill the deal or force you to pay for costly corrections. And most importantly, improper electrical work is dangerous. It can cause fires, electrocution, or damage to your appliances and electronics.
When you hire Carroll Service Co, every electrician carries current Texas licensing and full insurance. We handle permits and inspections so everything is documented and compliant. You’re not taking shortcuts that come back to bite you later.
Most electrical repairs take a few hours. Simple fixes like replacing a faulty outlet, fixing a tripped breaker, or troubleshooting a circuit usually get done in one visit. Our trucks carry the parts we need, so we’re not leaving to pick up materials.
Bigger jobs like rewiring a room, upgrading a panel, or installing a generator take longer. Panel upgrades usually take a full day once permits are in place. Generator installations can take one to two days depending on the setup and whether we need to run new gas lines or concrete pads.
We give you a realistic timeline before we start. If something takes longer than expected, we let you know why and what’s involved. You’re not left wondering when your power will be back on or when the job will be finished.
Circuit breakers trip when they’re overloaded, when there’s a short circuit, or when the breaker itself is worn out. In Denton County, the most common cause is overloading. Older homes with 100-amp panels weren’t designed for the electrical load that modern households demand.
When you run your AC, charge devices, use kitchen appliances, and have electronics plugged in throughout the house, you’re pulling more power than those older systems were built to handle. The breaker trips to prevent overheating and fire. That’s actually the breaker doing its job, but it’s a sign your system needs an upgrade.
Short circuits happen when wiring gets damaged or connections come loose. That’s a bigger problem and needs immediate attention. If your breaker trips and won’t reset, or if you smell burning or see scorch marks, don’t keep flipping it. Call us to inspect it. Ignoring that kind of issue leads to fires.
Yes. We install EV charging stations for homes and businesses throughout Denton County. Most electric vehicles need a dedicated 240-volt circuit, similar to what your dryer uses. Depending on your panel’s capacity, we may need to upgrade it to handle the additional load.
The installation process involves running the circuit from your panel to the charging location, mounting the charging unit, and making sure everything is grounded and code-compliant. Most installations take a day. If your garage or carport doesn’t have adequate electrical capacity, we assess what’s needed and give you a clear plan before starting.
EV charging at home is faster and more convenient than relying on public chargers. With a Level 2 home charger, most vehicles fully charge overnight. We make sure your electrical system can support that without tripping breakers or overloading your panel every time you plug in.
Look for a licensed electrical contractor with verifiable experience and a solid local reputation. Check their BBB rating and read reviews from actual customers. Make sure they’re insured, because electrical work carries real risk and you don’t want to be liable if something goes wrong.
Ask about their process for permits and inspections. Any reputable electrical company will handle that as part of the job. If someone tells you permits aren’t necessary or offers to skip that step to save money, walk away. Unpermitted work creates problems with insurance and resale value.
Get a written estimate before work starts. It should include labor, materials, permits, and any other costs. If the estimate is vague or the contractor won’t put it in writing, that’s a red flag. You should know exactly what you’re paying for and what’s included. We provide transparent pricing and detailed estimates so you can make an informed decision without surprises.
