Your breaker shouldn’t trip every time you run the microwave and the AC at the same time. That’s not normal, and it’s not something you should just live with.
Most homes in Lake Dallas—especially those built before 2000—weren’t wired for the kind of power load we’re putting on them today. You’ve added smart TVs, home offices, EV chargers, high-efficiency HVAC systems, and a dozen devices plugged in at all times. Your electrical panel is doing its best, but it wasn’t designed for this.
When your system can’t keep up, you get flickering lights, warm outlets, breakers that trip constantly, and in the worst cases, real fire hazards. As a residential electrician in Lake Dallas, we can assess your load, identify weak points, and either redistribute circuits or recommend an upgrade that actually matches how you live now. You shouldn’t have to unplug things to use your home.
Carroll Service Co has been serving Lake Dallas and the surrounding DFW area for over 25 years. We’re not a franchise or a call center—we’re a family-owned electrical contractor with licensed electricians who show up when we say we will.
We hold an A+ rating with the Better Business Bureau and multiple Super Service Awards from Angie’s List. Every job is permitted, inspected, and done to current Texas electrical code. That’s not something every contractor can say, and it matters when you’re dealing with something as critical as your home’s electrical system.
Lake Dallas sits in a deregulated energy market, which means you’ve got options when it comes to your provider—but your wiring, panel, and surge protection still need to meet code and handle real-world demand. We’ve worked in this area long enough to know what fails first and what lasts.
When you call, we’ll ask a few questions to understand what’s going on—whether it’s an emergency or something you’ve been putting off. If it’s urgent, we offer same-day service and can typically get to Lake Dallas within 60 to 90 minutes.
Once we’re on-site, we’ll inspect the issue, test your system, and explain what’s happening in plain terms. You’ll get upfront pricing before any work starts—materials, labor, timeline. No hidden fees, no vague estimates that balloon later.
If the job requires a permit, we pull it. If it needs an inspection, we schedule it. You’re not responsible for chasing down code compliance or wondering if the work was done right. That’s on us, and we make sure it passes the first time.
After the work is done, we walk you through what we did, answer any questions, and provide warranty coverage on both parts and labor. If something doesn’t perform the way it should, we come back and make it right.

We handle the full range of residential and commercial electrical work. That includes troubleshooting and repairing faulty wiring, upgrading outdated breaker panels, installing GFCI outlets in kitchens and bathrooms, adding dedicated circuits for high-draw appliances, and designing recessed lighting layouts that actually make sense for your space.
Whole-home surge protection is now required under the 2023 National Electrical Code for any new service or panel upgrade in municipalities enforcing current code. Even if your city hasn’t adopted it yet, it’s worth installing. Lake Dallas sees severe thunderstorms, and lightning-induced surges can fry electronics, shorten appliance lifespan, and cost you thousands in replacements. A quality surge protector at the panel level stops that before it reaches your devices.
We also install backup generators and size them correctly based on your actual load—not just a guess. A 20kW unit typically covers most homes between 2,000 and 3,000 square feet with central air, but we calculate your specific needs during a free on-site assessment. If you work from home or have medical equipment that can’t go offline, a generator isn’t a luxury—it’s a necessity.
EV charging stations are another growing request. We’ll install a Level 2 charger, run a dedicated 240V circuit, and make sure your panel can handle the load without compromising the rest of your system.
If your breakers trip frequently, your panel feels warm to the touch, or you’re still using a fuse box, it’s time to upgrade. Panels typically last 25 to 40 years, but they can become obsolete sooner if your power demands increase.
Most older panels in Lake Dallas were installed when homes used far less electricity. Adding a home office, EV charger, or high-efficiency HVAC system can push your panel past its safe capacity. When that happens, you’ll notice lights dimming when appliances kick on, outlets that don’t work reliably, or breakers that won’t reset.
We can perform a load calculation to see if your current panel can handle your usage. If it can’t, upgrading to a 200-amp panel gives you room to grow and brings your system up to current code. It also makes your home safer and more attractive to buyers if you ever sell.
A plug-in surge protector only protects the devices connected to it. A whole-home surge protector installs at your electrical panel and protects everything in your house—appliances, HVAC systems, electronics, and anything else wired into your system.
Surge protectors work by diverting excess voltage away from your equipment during a power surge. Surges can come from lightning strikes, utility grid switching, or even large appliances cycling on and off inside your home. Over time, repeated smaller surges degrade sensitive electronics and shorten their lifespan.
Whole-home surge protection is now required by the 2023 NEC for new electrical services and panel upgrades in areas enforcing the updated code. Even if it’s not required in your area yet, it’s one of the best investments you can make. Installation typically costs between $300 and $1,200 depending on the unit and your panel setup, and it can save you thousands in damaged equipment.
It depends on your current load and how your circuits are distributed. Adding outlets doesn’t automatically mean you need a panel upgrade, but it does require careful planning to avoid overloading existing circuits.
Each circuit in your home is rated for a specific amperage—usually 15 or 20 amps. If you’re adding outlets to a room that’s already maxing out its circuit, you’ll either need to run a new dedicated circuit or redistribute the load. We’ll test your panel, calculate your total usage, and determine whether you have capacity to spare.
In some cases, older panels are already running at or near capacity, especially if you’ve added modern appliances or technology over the years. If that’s the situation, adding outlets safely might require a panel upgrade. It’s not about the outlets themselves—it’s about whether your system can handle the additional draw without creating a safety risk.
A full standby generator installation typically takes one to three days, depending on the size of the unit, your home’s electrical setup, and whether you need a concrete pad or natural gas line run.
The process starts with a site assessment to determine the best location for the generator—it needs to be close enough to your home for efficient wiring but far enough to meet code clearances. We’ll calculate your electrical load to size the generator correctly, then coordinate with your utility company if a gas line needs to be installed or upgraded.
Once the generator is in place, we install a transfer switch that automatically detects when you lose power and switches your home over to generator power within seconds. After installation, we test the system to make sure it kicks on properly and handles your load without issue. You’ll also receive a walkthrough on basic operation and maintenance so you know what to expect when the power goes out.
Yes. Most electrical work beyond simple repairs requires a permit in Lake Dallas, and it’s our responsibility to pull it—not yours.
Permits exist to ensure that electrical work meets current safety codes and gets inspected by a qualified official. Work that typically requires a permit includes panel upgrades, new circuits, generator installations, EV charger installations, and any rewiring or additions that affect your home’s electrical capacity.
Some homeowners try to skip the permit process to save time or money, but that’s a mistake. Unpermitted work can fail inspection when you sell your home, void your homeowner’s insurance if something goes wrong, and create serious safety hazards if the work wasn’t done correctly. When you hire us as your licensed electrician in Lake Dallas, we’ll handle the permit, schedule the inspection, and make sure everything passes the first time.
If your neighbors have power but you don’t, the issue is likely inside your home—not with the utility company. Start by checking your main breaker panel to see if the main breaker or any individual breakers have tripped.
If the main breaker is off or won’t stay on when you try to reset it, don’t keep flipping it. That usually means there’s a short circuit, ground fault, or overload somewhere in your system, and forcing the breaker back on can cause damage or create a fire hazard. Call us right away.
If some rooms have power and others don’t, you might have a tripped breaker on a specific circuit, a blown fuse (if you have an older fuse box), or a problem with the wiring in that part of your home. We can trace the issue, identify the cause, and get your power restored safely. We offer 24-hour emergency service in Lake Dallas for situations like this, and we can typically arrive within 60 to 90 minutes.
