You shouldn’t think about your electrical system until you need to plug something in. No breakers tripping when you run the dishwasher and microwave at the same time. No lights dimming when the AC kicks on. No warm outlets or burning smells near your panel.
That’s what properly functioning residential electrical services look like. Your home handles the load without complaint. Your family stays safe. Your electronics last longer because they’re not getting fried by power surges every time a storm rolls through Lake Dallas.
Most homes built before 2000 weren’t designed for how you live now. You’ve got more devices, bigger appliances, and higher power demands than the original wiring was meant to handle. When your electrical system can’t keep up, you get the warning signs: repeated breaker trips, outlets that don’t work consistently, or panels that feel warm to the touch. Those aren’t just inconveniences. They’re fire risks.
Carroll Service Co is a family-owned electrical contractor that’s been serving Lake Dallas and the Dallas-Fort Worth area for over 25 years. We’re fully licensed, insured, and hold an A+ rating with the Better Business Bureau.
We’re not the cheapest option, and that’s intentional. You’re paying for electricians who show up with fully stocked trucks, find the actual source of your electrical problems, and use commercial-grade materials that last decades instead of years. We explain what’s wrong in plain English, give you real options, and complete most repairs during the first visit.
Lake Dallas has a mix of older homes and newer construction, and we’ve worked on both. We know which neighborhoods have aluminum wiring that needs updating. We know how many homes are still running on 100-amp panels that can’t handle modern electrical loads. We’ve seen what happens when DIY repairs go wrong or when someone hires the lowest bidder who cuts corners.
You call or submit a request online. We typically respond within an hour during business hours and schedule a time that works for you. For emergencies, we’re usually on-site in Lake Dallas within 60 to 90 minutes.
When we arrive, we listen to what’s been happening. Then we inspect your electrical system to find the real issue, not just the symptom. A breaker that keeps tripping might be overloaded, or it might be a sign of faulty wiring, a failing breaker, or a short circuit somewhere in your home. We test, diagnose, and explain what we find.
Before we do any work, you get upfront pricing. No surprises when the job’s done. If you approve, we handle the repair or installation right then if we have the parts on our truck, which we usually do. After the work is complete, we test everything to make sure it’s functioning properly and meets current electrical codes.
You get a warranty covering both parts and labor. If something goes wrong with our work, we come back and fix it at no additional cost. Most panel upgrades come with warranties lasting up to five years.

Electrical troubleshooting for homes covers everything from outlets that stopped working to circuits that trip without explanation. We trace the problem through your wiring system, identify what’s causing it, and fix it properly. That includes checking for loose connections, damaged wiring, overloaded circuits, or outdated components that don’t meet current safety standards.
Panel upgrades are common in Lake Dallas because many homes were built with 100-amp service. When you’re running central air, a dryer, kitchen appliances, and charging multiple devices, that’s not enough. We install 200-amp panels that give you the capacity to power your home without constant breaker trips. This includes pulling permits, passing inspections, and making sure your new panel meets National Electrical Code requirements.
Home wiring installation covers new circuits for additions, updated wiring to replace old aluminum or cloth-insulated wire, and GFCI outlets in kitchens, bathrooms, and outdoor areas where water and electricity don’t mix well. We also install whole-house surge protection, which is critical in North Texas where summer storms cause power fluctuations that damage electronics, appliances, and HVAC systems over time. Lighting installation includes recessed lighting, outdoor security lights, and modern fixtures that work with smart home systems.
If you’re adding an electric vehicle charging station or a backup generator, we handle the entire installation: site evaluation, electrical integration, automatic transfer switches, permits, and inspections. Generators turn on automatically within seconds of losing power, keeping your refrigerator, HVAC, and essential systems running during outages.
Your panel needs an upgrade if breakers trip frequently, especially when you’re running multiple appliances at the same time. If your lights dim when the AC or another large appliance turns on, that’s a sign your panel can’t handle the load.
Other warning signs include a panel that feels warm to the touch, outlets or switches that are discolored or smell like burning plastic, or breakers that won’t reset after tripping. If your home was built before 1990 and still has the original panel, it’s likely undersized for how you use electricity today.
Most older Lake Dallas homes have 100-amp panels. Modern homes typically need 200-amp service to safely power HVAC systems, kitchen appliances, electronics, and everything else you plug in daily. Upgrading your panel reduces fire risk, prevents constant breaker trips, and gives you the capacity to add new circuits for things like EV chargers or home additions.
Outlets stop working for several reasons. The most common is a tripped GFCI outlet somewhere on the same circuit. GFCI outlets have reset buttons and are usually found in kitchens, bathrooms, garages, and outdoor areas. If one trips, it cuts power to other outlets downstream.
Loose wiring connections inside the outlet box can also cause outlets to fail or work inconsistently. Over time, wires can come loose from the terminal screws, especially in older homes. Sparking outlets are more serious and usually mean you have a loose connection, a damaged outlet, or a short circuit. Don’t keep using an outlet that sparks.
If multiple outlets stop working at once, you might have a tripped breaker or a bigger wiring issue. Aluminum wiring, which was common in homes built during the 1960s and 70s, expands and contracts with temperature changes, leading to loose connections that cause outlets to fail or overheat. We can test your outlets, trace the circuit, and fix whatever’s causing the problem.
Service call fees typically range from $89 to $150, which covers the trip to your home and the initial diagnosis. Once we identify the problem, you get upfront pricing for the repair before any work starts. Simple fixes like replacing an outlet or resetting a tripped breaker might cost $100 to $200.
More involved repairs like replacing a circuit breaker, rewiring a room, or installing new circuits range from $300 to $1,500 depending on the scope. Panel upgrades usually run between $2,000 and $4,500, depending on whether you’re upgrading from 100-amp to 200-amp service and how much additional work is needed to bring everything up to code.
Whole-house surge protection costs around $400 to $800 installed. Generator installations vary widely based on the size of the unit and whether you need a new gas line, but expect to invest $5,000 to $15,000 for a complete setup. We give you exact pricing before starting any work, so there’s no confusion about what you’re paying for.
Lights that flicker or dim when your AC, refrigerator, or other large appliances kick on usually mean your electrical system is struggling to handle the load. This happens when your panel doesn’t have enough capacity or when multiple high-draw appliances share the same circuit.
It can also indicate loose wiring connections at your panel, at the meter base, or at the utility connection outside your home. Loose connections create resistance, which causes voltage drops that make your lights flicker. In some cases, the problem is with the utility company’s equipment, not your home’s wiring.
If flickering happens throughout your home and isn’t tied to a specific appliance, you might have a loose neutral wire, which is a serious safety issue. If it only happens in one room or on one circuit, the problem is likely isolated to that area. We can test your electrical system, measure voltage drops, and determine whether you need a panel upgrade, dedicated circuits for large appliances, or repairs to your existing wiring.
Most panel upgrades take four to eight hours, depending on the complexity of your electrical system and whether we need to run new circuits or update other components at the same time. The work includes shutting off power to your home, removing the old panel, installing the new one, reconnecting all your circuits, and testing everything to make sure it works properly.
You’ll be without power during the installation, so plan accordingly. We schedule panel upgrades during times that minimize disruption, and we work efficiently to get your power back on as quickly as possible. If your upgrade requires coordination with the utility company to disconnect and reconnect service, that can add time to the process.
After installation, we handle the permit and inspection process. Your new panel needs to pass inspection before it’s fully approved, but you’ll have power restored as soon as the installation is complete. The entire process from scheduling to final inspection usually takes one to two weeks, with most of that time spent waiting for inspection appointments, not actual work.
If you want your electronics, appliances, and HVAC system to last as long as they’re designed to, yes. North Texas gets severe thunderstorms that cause power surges, and those surges degrade sensitive electronics over time even if they don’t cause immediate failure. You might not notice the damage right away, but your devices die sooner than they should.
Whole-house surge protection installs at your electrical panel and stops surges before they reach your outlets. It protects everything in your home, not just what’s plugged into individual surge protector strips. Power surges don’t just come from lightning. They also happen when large appliances cycle on and off, when there are issues with the power grid, or when utility companies switch equipment.
A whole-house surge protector costs a few hundred dollars installed and can save you thousands in damaged electronics, appliances, and HVAC components. HVAC circuit boards are especially vulnerable to surge damage and expensive to replace. If you’ve already invested in a new panel, adding surge protection at the same time makes sense and usually costs less than adding it later.
