Is Your McKinney Home's Electrical Panel Keeping Up?
Many homes across McKinney and North DFW were built between the 1980s and early 2000s, back when a 100-amp panel was plenty. That's just not the case anymore. Today, EV chargers, smart home systems, dual-zone HVAC, induction cooktops, and whole-home generators can place a much greater load on the electrical system. An electrical panel upgrade may be appropriate when the existing panel no longer has enough capacity for planned additions or the home's current load.
McKinney's rapid growth has also brought many older homes back onto the market. Homebuyers sometimes discover an undersized, outdated, or unsafe panel during inspection. Others notice the problem only after moving in, when breakers begin tripping as multiple appliances operate at once. The right solution is not always a larger panel. A qualified assessment can determine whether your home needs a full upgrade, panel replacement, or a sub-panel for a specific area.



Eaton Certified Panel Installations: What It Means for You
Benchmark Electrical Services uses Eaton panels and components for the majority of our residential panel work. The reason is straightforward: Eaton's equipment carries a higher surge current capacity rating than standard builder-grade panels, giving your home a stronger baseline of protection.
Eaton is also the primary brand our main supplier carries, and it happens to be one of the best in the industry, so the practical and the technical reasons line up. We've built our supply chain and technical familiarity around Eaton's BR and CH series products, which means faster parts availability and equipment our team installs consistently, job after job.
Signs Your Electrical Panel Needs to Be Replaced
Not sure if your panel needs attention? Here's what to look, and listen, for.
Circuit Breakers Trip Frequently
An occasional trip is normal. But if the same breaker or worse, your main breaker keeps tripping, that's your panel telling you it can't keep up with the load you're asking of it, or a breaker inside is starting to fail.
Flickering or Dimming Lights
If your lights dim or flicker every time the HVAC kicks on or the dishwasher starts, that's not a bulb problem. That's your panel struggling to distribute power consistently across your home.
Burning Smell or Discoloration
A burning smell near your panel, scorch marks around the breakers, or visible arcing and pitting on the breakers, bus bar, or other termination points inside the box are serious warning signs of overheating and a real fire risk. If you notice burning, unusual heat, smoke, or visible damage around the panel, stop using the affected equipment and call us right away.
Warm or Hot Panel
Your panel shouldn't be warm to the touch, ever. Heat usually points to overloaded circuits or a main breaker that's starting to fail.
Outdated Fuse Box
Some older homes still have original fuse boxes rather than modern circuit breakers. These systems may lack the capacity and protection features required for today's electrical loads and may make future electrical additions more difficult. If your home still relies on fuses, Benchmark Electrical Services can evaluate the system and determine whether an upgrade is appropriate.

Zinsco or Federal Pacific Brand
Check the label on your panel. If it reads Zinsco, Sylvania, or Federal Pacific (FPE), we'd recommend prioritizing replacement whether or not you're seeing symptoms yet. These older brands have documented safety concerns and can cause problems that aren't immediately apparent during normal use.

Electrical Panel Upgrade Cost in McKinney & North DFW
A complete panel upgrade with current National Electrical Code requirements typically runs $8,000 to $10,000. That's up from the $3,000 to $5,000 range electricians could offer in years past, the increase reflects code requirements that have gotten more demanding over time, not a change in what individual homes need. Because these code requirements apply everywhere, cost doesn't really move downward from project to project, it moves up as code standards evolve.
Costs can still vary based on the condition of your specific panel and service: a straightforward upgrade is less involved when the meter base, service entrance, and existing wiring are already in good shape. Costs can increase further when the meter base needs replacement, the service entrance requires additional work, or the panel is located farther from the meter.
If the cost is a stretch right now, we offer financing through Service Finance Company. And every estimate is free, so there's no risk in finding out where you stand.

Subpanel or Full Panel Upgrade: Which Do You Need?
This is one of the most common questions we get on a panel call, so let's break it down.

When a Sub-Panel Makes Sense
A subpanel may be appropriate for a detached garage, workshop, pool equipment, or home addition that needs several dedicated circuits. It can also make sense when the main panel has enough unused capacity but a particular area needs additional circuits.

When a Full Upgrade Makes More Sense
A full upgrade may be the better option when the main service is undersized, such as a 100-amp system, or when you're adding significant electrical loads across the home. An outdated or failing main panel is another reason replacement may be preferable to adding a subpanel. A subpanel installed at the same time as the main panel is also often due for replacement alongside it, since both tend to reach the end of their service life together.

How Benchmark Electrical Services Makes the Call
Benchmark Electrical Services evaluates the home's total electrical load, available breaker capacity, panel age and condition, and the equipment you plan to add. That assessment helps determine whether a subpanel or full upgrade is the more appropriate solution.
Frequently Asked Questions
The time required for an electrical installation service depends on the type of project. Simple tasks like installing new outlets or switches can take less than an hour, while larger jobs like adding dedicated circuits or wiring outdoor spaces may require several hours. Our electricians provide a clear time estimate before starting work, so you know exactly what to expect.
Yes. Every panel upgrade in McKinney and across North DFW requires an electrical permit and a city inspection. Benchmark Electrical Services pulls the permit and schedules the inspection for you. That inspection matters for insurance purposes and for your home's resale value down the line.

Many modern homes use 200-amp service, but the appropriate size depends on the home's electrical load.
