Your breakers trip when you run the AC and microwave at the same time. Lights dim when the dryer kicks on. Outlets feel warm to the touch.
These aren’t minor annoyances. They’re warnings that your electrical system is overloaded and potentially dangerous.
Most homes in Flower Mound built before 1990 run on 100-amp panels. That was fine when homes had one TV and a window unit. Now you’re running central air, smart devices, multiple computers, electric vehicle chargers, and high-efficiency appliances. Your panel can’t keep up.
Upgrading to a 200-amp panel means your system can handle modern electrical demands without strain. You’ll stop worrying about tripped breakers during dinner. Your lights stay steady. Your electronics stay protected from voltage fluctuations that shorten their lifespan.
You also get real protection during North Texas storms. Whole-house surge protection guards everything plugged into your home. A backup generator keeps your AC running during summer outages and your heat working during winter freezes.
Carroll Service Co is a family-owned electrical contractor serving Flower Mound and the Dallas-Fort Worth area for over 25 years. We hold an A+ rating with the Better Business Bureau and multiple Super Service Awards from Angie’s List.
Every electrician on our team carries current Texas licensing and insurance. We know Flower Mound’s building codes, understand how North Texas weather affects electrical systems, and stock our trucks with commercial-grade components that last.
We’re not the cheapest option in town, and that’s intentional. You’re paying for work that passes inspection the first time, components that won’t need replacing in five years, and electricians who show up when they say they will. We’ve built our reputation here by doing the job right, not by doing it fast or cheap.
You call or submit a request online. We schedule a time that works for you, usually within 24 hours for non-emergencies. For urgent issues like sparking outlets or complete power loss, we offer same-day emergency service.
Our electrician arrives in a fully stocked truck. We assess the problem, explain what’s wrong in plain language, and give you an upfront price before starting any work. No surprises when the job’s done.
Most repairs finish during the first visit. Panel upgrades and generator installations take longer and require permits. We handle all the paperwork, schedule inspections, and make sure everything meets current code requirements.
When we’re done, we test the system, clean up completely, and walk you through what we did. All work comes with a warranty covering both parts and labor. Most installations carry a 2-5 year warranty depending on the scope.
If something doesn’t work right after we leave, we come back and fix it. That’s not a marketing line. It’s how we’ve stayed in business for 25 years in the same community.

We handle the full range of residential and commercial electrical work. Panel upgrades from 100-amp to 200-amp service. Complete rewiring for older homes with outdated or dangerous wiring. New circuit installation for home additions, workshops, or EV chargers.
Flower Mound’s summer heat and winter storms make backup power essential. We install whole-home generators that kick on automatically when the grid goes down. Your AC keeps running during August outages. Your pipes don’t freeze when winter storms knock out power for days.
Whole-house surge protection is standard on most of our installations. North Texas sees frequent lightning strikes and grid fluctuations that fry electronics. A quality surge protector at your panel guards everything in your home, not just what’s plugged into power strips.
We also install recessed lighting, upgrade outlets to USB-equipped models, add dedicated circuits for high-draw appliances, and perform electrical safety inspections for home buyers. Every job uses UL-listed parts and commercial-grade components that outlast standard residential materials.
All work gets permitted and inspected according to Flower Mound and Texas Department of Licensing and Regulation requirements. We don’t cut corners on code compliance because that’s what keeps your family safe and your insurance valid.
Your panel needs upgrading if breakers trip frequently, lights dim when appliances start, you smell burning near the panel, or you see rust or scorch marks on the panel box. These are safety issues, not just inconveniences.
Most Flower Mound homes built before 1990 have 100-amp panels. If you’ve added central AC, a hot tub, an EV charger, or multiple high-efficiency appliances since then, your panel is likely undersized. Modern homes typically need 200-amp service to safely handle today’s electrical load.
Another clear sign is if you’re using extension cords regularly because you don’t have enough outlets. That means you’re overloading circuits, which creates fire risk. Upgrading your panel and adding circuits solves that problem permanently.
Power strip surge protectors guard whatever’s plugged into them. They’re better than nothing, but they don’t protect hardwired appliances like your AC, refrigerator, garage door opener, or smart home system.
A whole-house surge protection system installs at your electrical panel and protects everything in your home. When lightning strikes nearby or the grid fluctuates, the system diverts excess voltage before it reaches your devices.
North Texas gets severe thunderstorms year-round. A single surge can destroy thousands of dollars in electronics. Whole-house protection costs a fraction of replacing a fried AC compressor, smart thermostat, TV, and computer. We install them on most panel upgrades because the protection is worth far more than the cost.
Most residential panel upgrades take one full day. We start in the morning, shut off power to your home, remove the old panel, install the new 200-amp panel, reconnect all circuits, and restore power by late afternoon.
The job requires a permit from the Town of Flower Mound and a final inspection. We handle all the paperwork and schedule the inspection. The inspector typically comes within a few days of completion.
Your power is only off during the actual installation, usually 4-6 hours. We work efficiently because we know you need your AC, refrigerator, and internet running. If the job runs longer than expected, we stay until it’s finished correctly. We don’t leave your home without power overnight.
That depends on what happens when your power goes out. If you can handle a few hours without AC in August or heat in February, you might not need one. But North Texas storms can knock out power for days, not hours.
Summer outages mean no AC when it’s 100 degrees outside. Your refrigerator stops working. Your sump pump quits if you have one. Winter outages mean no heat, and frozen pipes can cause thousands in damage.
A whole-home generator connects to your natural gas line and starts automatically within seconds of losing grid power. You don’t do anything. Your AC, heat, refrigerator, and essential circuits keep running like nothing happened. Most Flower Mound homeowners who install generators wish they’d done it years earlier, especially after living through a multi-day outage.
First, verify they hold a current license from the Texas Department of Licensing and Regulation. Every legitimate electrician in Texas must be licensed. Ask to see it. Check that they carry general liability insurance and workers’ compensation coverage.
Second, check their Better Business Bureau rating and online reviews. Look for patterns in complaints, not just star ratings. Do they show up on time? Do they clean up after themselves? Do they stand behind their work when something goes wrong?
Third, get a written estimate before work starts. The estimate should specify what’s included, what materials they’ll use, and the total cost. If an electrician won’t give you a written price upfront, that’s a red flag. You shouldn’t be surprised by the bill when the job’s done.
Simple repairs like replacing an outlet or fixing a tripped breaker usually run $150-$300. Adding a new circuit for an appliance typically costs $400-$800 depending on distance from the panel and complexity.
Panel upgrades from 100-amp to 200-amp service generally range from $2,500-$4,500 for most Flower Mound homes. That includes the new panel, permit, labor, and inspection. Whole-house surge protection adds another $400-$700.
Backup generator installation varies widely based on size and features. A basic system that covers essential circuits starts around $4,000-$6,000 installed. Whole-home generators that power everything run $8,000-$15,000 depending on your home’s electrical load. These prices include the generator, transfer switch, gas line connection, permit, and startup.
