Your breakers stop tripping every time you run the dryer and microwave at the same time. Your lights don’t flicker when the AC kicks on. You can charge your phone, run your home office, and keep your family comfortable without wondering if your panel can handle it.
That’s what a properly functioning electrical system looks like. And if yours isn’t there yet, you’re not alone—most homes in Hackberry built before 2000 are still running on 100-amp panels that weren’t designed for modern life.
You shouldn’t have to ration power in your own home. When your electrical system is upgraded to handle today’s demands, you get reliability. You get safety. You get the confidence that comes from knowing your home’s wiring won’t fail you during a Texas heat wave or winter freeze.
Carroll Service Co is a family-owned electrical contractor serving Hackberry and the broader Dallas-Fort Worth area for over 25 years. We’re not a franchise. We’re not a call center routing you to the lowest bidder. We’re Texas licensed electricians who live and work in this community.
Our A+ BBB rating and multiple Super Service Awards didn’t come from marketing. They came from showing up on time, doing the work right, and standing behind it. Every electrician on our team carries current Texas licensing and insurance, because that’s not optional—it’s the baseline for doing this work safely.
Hackberry sits in one of the fastest-growing parts of Denton County, and we’ve watched this area expand. We know the housing stock here. We know the common electrical issues older homes face, and we know how to bring them up to code without unnecessary upselling.
You call or submit a request. We schedule a time that works for you—same day if it’s urgent. No waiting around for a four-hour window.
Our electrician shows up in a fully stocked truck. We assess the issue, explain what’s going on in plain terms, and give you upfront pricing before any work starts. No surprises on the invoice.
If it’s a simple repair, we often finish it the same visit. If it’s a bigger job—like a panel upgrade or home rewiring—we walk you through the timeline, pull the necessary permits, and coordinate inspections. You’re not left guessing what happens next.
Once the work is done, we test everything, clean up, and make sure it passes inspection the first time. Then we back it with a warranty that actually means something. If something goes wrong with our work, we fix it. That’s the deal.

We handle electrical panel upgrades for homes that need more capacity. If your panel is over 20 years old or you’re adding major appliances or an EV charger, an upgrade isn’t optional—it’s a safety requirement. We install UL-listed panels that meet current NEC code and can handle modern electrical loads.
Home rewiring services cover older homes with outdated or unsafe wiring. Aluminum wiring, knob-and-tube, ungrounded outlets—these aren’t just code violations, they’re fire hazards. We rewire sections or entire homes depending on what the inspection reveals.
Electrical troubleshooting is where experience matters. Intermittent problems, phantom tripping, voltage drops—we’ve seen it all. We don’t guess. We test, diagnose, and fix the actual problem, not just the symptom.
We also install whole-house surge protection, backup generators, recessed lighting, and EV charging stations. Hackberry homeowners are increasingly adding these features, and we make sure they’re installed correctly the first time. Texas storms and grid issues aren’t going anywhere, so having a backup generator isn’t just convenient—it’s becoming essential for families who can’t afford to lose power for days.
Panel upgrades in Hackberry typically range from $2,500 to $4,500 depending on the amperage, location of your existing panel, and whether any additional wiring or grounding work is needed. A standard upgrade from a 100-amp to a 200-amp panel with a new breaker box usually falls in the middle of that range.
The price includes the panel itself, labor, permits, and inspection fees. If your home needs a new meter base or service line from the utility, that adds cost. We give you a detailed quote before starting so you know exactly what you’re paying for.
Financing options are available if you need them. But more importantly, a panel upgrade isn’t just an expense—it’s a safety investment that protects your home from electrical fires and gives you the capacity to run modern appliances without overloading your system.
Yes. Any significant electrical work in Hackberry requires a permit, and that includes panel upgrades, rewiring, new circuits, and generator installations. Minor repairs like replacing an outlet or switch typically don’t require one, but anything that involves new wiring or changes to your electrical system does.
Permits aren’t red tape—they ensure the work gets inspected and meets safety codes. If you ever sell your home, unpermitted electrical work can kill a deal or force you to redo it at your expense. Insurance companies can also deny claims if they find out major electrical work was done without permits.
We pull permits for every job that requires one. We schedule the inspections. We make sure everything passes the first time. You don’t have to deal with the city or worry about whether the work is legal. That’s part of what you’re paying a licensed electrical contractor to handle.
A full home rewiring in Hackberry typically takes three to seven days depending on the size of your home, whether walls need to be opened, and how accessible your attic and crawl spaces are. A 1,500-square-foot home with good access might take three to four days. A larger two-story home with limited access can take a full week.
We work in phases to minimize disruption. You won’t be without power for days—we rewire sections at a time and keep essential circuits active. If you need to stay in the home during the work, we coordinate around your schedule.
The timeline also depends on inspections. We schedule those as we go, and once the final inspection passes, you’re done. Rewiring isn’t a quick job, but it’s one of the most important upgrades you can make to an older home. It eliminates fire hazards, brings your home up to code, and gives you a safe electrical system that’ll last decades.
If your breakers trip frequently, that’s the most obvious sign. But it’s not the only one. Flickering lights when appliances turn on, outlets that feel warm to the touch, a panel that’s warm or makes buzzing sounds—these all point to an overloaded or failing panel.
Another red flag is if you’re still using a fuse box or your panel is over 20 years old. Older panels weren’t designed for the electrical load modern homes demand. Between HVAC systems, kitchen appliances, home offices, and EV chargers, today’s homes pull significantly more power than they did even a decade ago.
If you’re planning any major renovations or adding high-draw appliances, your existing panel might not have the capacity. We can assess your current setup and tell you whether an upgrade is necessary or if you can get by with what you have. But if you’re already seeing warning signs, waiting doesn’t make it cheaper—it just increases the risk.
Yes. We install Level 2 EV chargers for Hackberry homeowners, and we make sure your electrical system can handle the load before we start. A Level 2 charger typically requires a 240-volt circuit and draws 30 to 50 amps depending on the model.
If your panel has the capacity, installation is straightforward. We run a dedicated circuit from your panel to the charger location, mount the unit, and test it. If your panel is already maxed out, we’ll recommend an upgrade first—you don’t want to overload your system just to charge your car.
Many state and federal programs in 2026 offer rebates and tax credits for EV charger installations, which can offset a significant portion of the cost. We can point you toward those programs, but you’ll need to verify eligibility on your own. The installation itself usually takes half a day, and once it’s done, you’ll charge your vehicle faster and cheaper than relying on public charging stations.
Yes. We offer 24/7 emergency electrical services for situations that can’t wait—like complete power loss, sparking outlets, burning smells from your panel, or exposed wiring. Electrical emergencies are safety hazards, and we prioritize those calls.
When you contact us for an emergency, we assess the situation and dispatch an electrician as quickly as possible. We can’t always arrive within minutes, but we respond the same day for true emergencies. If it’s something that can wait until morning without risk, we’ll tell you that too.
Emergency rates are higher than standard service calls because you’re paying for availability and fast response. But if your home is unsafe, waiting until business hours isn’t an option. We carry the tools and parts to handle most emergency repairs on the spot, so you’re not left without power or dealing with a dangerous situation overnight.
