Electrical Panel Upgrades Stories & Advice in Fairfax County

Peter’s Guide to Electrical Panel Upgrades in Fairfax County, VA (Stories & Advice)

Hello, I’m Peter – the owner of PRO Electric plus HVAC. If you’re a homeowner in Fairfax County, Virginia, and wondering about electrical panel upgrades, you’re in the right place.

I’ve been an electrician in Northern Virginia for years, helping folks in Fairfax, Herndon, Reston, Vienna, McLean, and all across Fairfax County keep their homes safe and powered. One of the most common (and important) jobs I handle is upgrading outdated electrical panels – whether it’s a 200 amp service upgrade for a growing family or a fuse box replacement in a historic home. In this conversational guide, I want to share some real customer stories, helpful insights, and friendly advice about electrical panel upgrades. My goal is to explain when and why you might need an upgrade, what the process (and cost) looks like, and why choosing a local expert matters.

No heavy technical jargon here – just an honest chat from me to you, the homeowner. By the end of this page, you’ll know the signs of a struggling panel, understand the benefits of a modern electrical service panel, and hopefully feel confident about the next steps. Upgrading your electrical panel can sound daunting, but I’m here to make it easy to understand.

So, grab a cup of coffee, and let me walk you through everything you should know about electrical panel upgrades in Fairfax County – sprinkled with a few stories from my own experiences helping your neighbors. Let’s get started!

Why Upgrading Your Electrical Panel is Crucial

You might be wondering, “Do I really need to worry about my electrical panel?” In many cases, the answer is yes – especially if you live in an older home or you’re pushing the limits of what your panel can handle. Your electrical panel (also called a breaker box or service panel) is the heart of your home’s electrical system. It’s what distributes electricity throughout your house, from your kitchen lights to your HVAC system. When that “heart” gets old, weak, or overloaded, everything connected to it is at risk.

Safety First: An outdated or malfunctioning panel can be more than just inconvenient – it can be dangerous. I’ve seen scorch marks inside old fuse boxes and melted wires behind ancient circuit breakers. Over the years working in places like Vienna and Annandale, I’ve come across panels that were literally overheating to the point of burning. Old electrical panels (or those infamous Federal Pacific or Zinsco breaker panels from decades ago) can fail to trip properly, meaning they won’t shut off when there’s an overload. That’s a serious fire hazard. Upgrading a worn-out panel is about protecting your home and family from electrical fires and shocks.

Modern Power Needs: Beyond safety, think about how much our lives have changed electrically. Many Fairfax County homes built in the 1960s or 1970s (there are plenty in Fairfax City, Herndon, and Springfield, for example) were originally equipped with 100-amp panels or small fuse boxes. Back then, folks didn’t have central AC, high-powered computers, multiple big-screen TVs, or electric car chargers. Today, we plug in so many devices and appliances that older panels struggle to keep up. If you’ve added new appliances (like a second refrigerator, a high-end HVAC system, or a hot tub), or if you’re considering an electric vehicle (EV) charger, you may absolutely need a service upgrade to 200 amps to handle the load.

Avoiding Unplanned Blackouts: I like to tell homeowners that an upgrade is cheaper and less stressful than dealing with an emergency. Imagine it’s a freezing winter night in McLean, and your aging panel finally gives out—suddenly half your house goes dark. I’ve responded to emergency calls where families were left without heat or lights because their old electrical panel failed unexpectedly. By upgrading on your own terms (instead of waiting for a failure), you avoid the chaos of losing power at the worst possible time.

In short, a healthy electrical panel is crucial for a safe, reliable home. If your panel is out-of-date or maxed out, it’s not a matter of if you’ll need an upgrade – it’s when. And it’s always better to upgrade before problems strike, rather than after. Next, let’s talk about how to tell when your panel might be giving you warning signs.

Signs Your Electrical Panel May Need an Upgrade

How do you know if your electrical panel is due for a change? Here are some telltale signs I’ve seen time and again in homes around Fairfax County. If you’re experiencing any of these, it might be time to consider an electrical panel upgrade or replacement:

Breakers Trip Frequently: If your circuit breakers are constantly tripping or fuses are blowing (in the case of an old fuse box) whenever you run certain appliances, that’s a red flag. For instance, if turning on the microwave and toaster at the same time causes a trip, your panel might be at capacity.
Lights Flicker or Dim: Do your lights flicker when the AC kicks in, or dim briefly when you vacuum? I helped a family in Reston who noticed their living room lights would dim every time their refrigerator compressor started. This often means your panel is struggling to supply consistent power and could use a capacity upgrade.
You Still Have a Fuse Box: Many older homes in areas like Herndon and Falls Church still have fuse-based panels. Fuses are old technology; they work, but they’re less convenient and can be a safety concern if the wrong fuses are used. If you have a fuse box (you screw in little fuses instead of flipping breakers), it’s definitely time to upgrade to a modern circuit breaker panel.
Old or Outdated Panel Model: Some electrical panel brands from the past have known safety issues. If your home has a Federal Pacific Electric (FPE) Stab-Lok panel or a Zinsco panel (common in mid-century homes), electricians like me consider them ticking time bombs. These panels have a history of breakers failing to trip when they should. If you see those names or an obviously decades-old panel in your home, you should have it inspected and likely replaced.
Burning Smell or Visible Damage: This one’s urgent. If you ever smell burnt plastic or see charring around the panel, or if the panel feels hot to the touch, turn off power and call an electrician immediately. Heat or burn marks indicate overheating or arcing inside the panel. I once encountered this in a Fairfax townhouse – the homeowner smelled something burning in the basement, and it turned out the main breaker was overheating and melting insulation. We performed an emergency panel replacement the very same day.
Not Enough Circuits / Reliance on Power Strips: If your home is using a lot of extension cords, power strips, or “octopus” outlets to have enough plugs, it might mean your panel doesn’t have enough circuits to meet your needs. Sometimes, older panels only have a limited number of circuits (say 8 or 12), whereas a modern panel can have many more. A panel upgrade can give you more circuits to distribute power more safely and conveniently.
Planning Major Upgrades: Okay, this one is more of a heads-up than a sign. If you’re planning a big renovation, adding a new appliance (like a second oven or an EV charging station), or finishing your basement in your Vienna or Oakton home, you should check if your current panel can handle it. Often, I’ll assess a project for a homeowner and find that an electrical service upgrade to 200 amps is needed to support their dream kitchen or home theater.

These signs are like your electrical panel’s way of waving a little white flag and saying, “Help!” If you notice one or more of them, it doesn’t automatically mean your panel is on its last legs, but it definitely warrants a professional evaluation. As I always tell my customers in McLean and Burke, it’s better to be proactive with electrical issues. Listen to what your home is telling you.

In the next section, we’ll dive into what an actual 200 amp panel upgrade involves and why 200 amps has become the modern standard for many households.

Upgrading to a 200 Amp Service – What It Means

You’ve probably heard about 200 amp panel upgrades or “200 amp service” when researching electrical updates. Many of the panel upgrades I do in Fairfax County are exactly that: taking an older 100-amp service (or even 60-amp in really old houses) and upgrading it to 200 amps. But what does that actually mean for you?

Think of amperage (amps) as the total “amount” of electricity available for your house to use at one time. A higher amp rating means your electrical system can handle more devices running simultaneously. Upgrading from 100 amps to 200 amps essentially doubles the electrical capacity of your home. This is increasingly important these days. For example, a house in Reston I worked on had a 100-amp panel that was fine back in 1975, but after the owners added central air conditioning, some new kitchen gadgets, and a home office setup with computers and servers, that 100-amp panel was straining. We upgraded them to a 200-amp service, and they’ve had no more trouble with tripping breakers despite their increased usage.

Why 200 Amps? In modern homes throughout Northern Virginia, 200 amps is the standard baseline. It provides enough capacity for typical large appliances (HVAC system, water heater, kitchen appliances), lighting, and general plug-in devices, with some headroom for new additions. If you plan on installing high-draw equipment like:

An electric vehicle charger (EV charging stations often need a 240V circuit and can draw 30-50 amps by themselves)
A hot tub or spa (these can pull a lot of power)
Heavy-duty workshop tools or equipment
A second HVAC system or an upgrade to an electric heat pump

…then a 200-amp panel is practically a must. In fact, when I consult with homeowners in Chantilly or Centreville who are thinking about long-term plans, I often recommend considering a 200-amp upgrade even if they might not use all that power right now. It’s about future-proofing your home.

The Upgrade Process in a Nutshell: Upgrading to 200 amps isn’t just swapping out a box. It typically involves:

Replacing the entire electrical panel with a new one rated for 200 amps.
Upgrading the service entrance cable (the heavy cable that brings power from the utility to your house) to ensure it can carry 200 amps safely.
Installing a new meter base or coordinating with the utility company (Dominion Energy here in Fairfax County) to handle the heavier service. Don’t worry, as your electrician I handle coordination with the power company and permits for you.
In some cases, an additional grounding system upgrade, because a higher capacity service needs proper grounding for safety.

Homeowners often ask me, “Will a 200-amp service cost me more in electric bills?” The answer is no – it doesn’t draw more electricity on its own; it just allows more usage if needed. Think of it like having a bigger garage. It doesn’t mean you have to fill it with more stuff, but you have the space when you need it.

For many houses in areas like Fairfax and Vienna, upgrading to 200 amps is like moving from a narrow country road to a two-lane highway – you get more room to operate without congestion.

It’s a solid investment in your home’s functionality and safety, especially if you anticipate greater electrical needs in the future. Next, I’ll touch on a specific case: what if your home still has an old-school fuse box instead of a breaker panel?

Replacing Old Fuse Boxes (Bringing Your Home Up to Code)

If your home is one of the older gems in Fairfax County, like some bungalows in Falls Church or farmhouses in Clifton, you might still have a fuse box instead of a modern circuit breaker panel. Fuse boxes were common in homes built pre-1960s. Instead of switches (breakers) that you flip, these panels have fuses that screw in. When a circuit overloads, the fuse burns out (you might know it as “blowing a fuse”) and has to be replaced.

Why Replace a Fuse Box? There are a few big reasons:

Convenience: With a fuse box, every time a circuit blows, you have to fumble for a new fuse and replace it. Circuit breakers, on the other hand, are easily reset with a flip of a switch. No hunting for that spare fuse in the dark.
Safety: Fuses themselves aren’t unsafe when used correctly, but the problem is many people put in oversized fuses or even bypass them (I’ve seen desperate homeowners put a penny behind a fuse to keep it from blowing – a dangerous trick!). This can allow circuits to draw more power than they’re safely rated for, overheating wires. A breaker panel is harder to tamper with and typically provides better overall protection. Also, most fuse boxes max out at 60 or 100 amps total capacity, which is usually not enough for today’s needs.
Insurance and Code Compliance: Some insurance companies charge higher premiums or even refuse coverage if a home still has an old fuse box, because they view it as a higher risk. Additionally, while an existing fuse box might be “grandfathered” in an old home, any significant electrical work or home sale inspection might flag it for upgrade. Fairfax County building codes today require modern electrical safety standards that fuse boxes generally don’t meet (like dedicated grounding, sufficient circuit capacity, etc.).

I recall upgrading a fuse box in a lovely older home in Herndon. The house had charm, but every time the owners ran their window AC unit and microwave together, a fuse would blow. They kept a stash of fuses in a kitchen drawer like it was 1955. We laughed about it after the upgrade, because once I installed a new 200-amp breaker panel, they could run all their appliances without a hitch – no more playing musical fuses. The homeowners also mentioned that their homeowner’s insurance gave them a better rate after the fuse box was replaced with a safer modern panel.

The Bottom Line: If you still have a fuse box, it’s probably well past time to replace it. You’ll gain peace of mind, better electrical performance, and likely a safer home. Plus, when it comes time to sell your house, “updated electrical panel” is a great selling point. Buyers in markets like Vienna and McLean love seeing that the critical electrical infrastructure has been modernized.

Now that we’ve talked about the technical stuff, let’s switch gears a bit. I want to share some personal stories from the field – real examples of how panel upgrades have helped your neighbors here in Fairfax County.

Real Stories from Fairfax County Homeowners

Nothing beats a real-life example to show why electrical panel upgrades make such a difference. Over the years, I’ve met hundreds of homeowners in our community, each with their own unique situation. Here are a few memorable stories from my time on the job. (Names are changed for privacy, but these are real scenarios I’ve encountered.) You might even recognize a bit of your own home in some of these tales!

Midnight Power Outage in Fairfax – Emergency Upgrade Saves the Day

One Friday night around 11 PM, I got a frantic call from a homeowner in Fairfax City. Let’s call him John. He said half the house had lost power and he heard a sizzle and pop from the electrical panel. John had a young baby in the house and was understandably panicked about the sudden outage (and the strange noises coming from the breaker box). I grabbed my gear and drove over immediately – this was clearly an emergency situation.

When I arrived, I found an old 125-amp panel that had been in the house since the 1970s. The main breaker was fried (literally blackened and melted on one side) and a section of the bus bar inside the panel had shorted out. The family was incredibly lucky it hadn’t started a bigger fire. I quickly and safely shut down the remaining power and explained to John and his wife that their panel had essentially “given up the ghost.” This wasn’t a simple repair; they needed a new panel right away.

That night, I was able to install a temporary solution to get the essential circuits (heat, fridge, a few lights) back on. First thing the next morning, I came back with a brand-new 200-amp panel. By midday Saturday, I had replaced their burnt-out panel with a modern one, coordinated with the city inspector for an emergency inspection (thanks to good relationships with local inspectors), and got their home fully powered again. John was relieved and frankly surprised that we managed to pull off a full electrical panel replacement on such short notice.

The lesson from this Fairfax story? If your panel is making weird noises or showing signs of failure, don’t wait. In their case, an emergency electrical panel upgrade was the only option, but ideally, you want to replace that aging panel before it fails at midnight. John told me later he sleeps better knowing the new panel is in place, and I sleep better too knowing another home is safe from electrical hazards.

Powering a Vienna Home Remodel – Upgrading to 200 Amps for a Dream Kitchen

Meet Susan from Vienna, a client who decided to remodel her 50-year-old home. She planned a gorgeous kitchen expansion with all the bells and whistles: dual ovens, a high-end refrigerator, wine cooler, and a powerful range hood. Plus, she was finishing her basement to add a home theater and a second HVAC system for that level. Ambitious project! When Susan contacted me for an electrical estimate for the renovation, I immediately checked her existing electrical panel. It was a 150-amp panel that had been chugging along for decades, and it was already close to maxed out with her current appliances and HVAC.

I sat down with Susan and discussed her plans. With all the new electrical load from the kitchen appliances and the additional HVAC unit, her existing service just wouldn’t cut it. She needed an electrical service upgrade to 200 amps to ensure her remodeled home would run smoothly. She was a bit concerned about the extra expense, so I shared some experiences of other homeowners who faced flickering lights and constantly tripping breakers after renovations because they hadn’t upgraded their panels. That convinced her – it’s a lot better to do it upfront than to redo work later.

We scheduled the panel upgrade to happen early in the renovation process. I coordinated with Dominion Energy to temporarily disconnect power on installation day, and by afternoon, we had a shiny new 200-amp panel in place with plenty of breaker space for all her new circuits. Once the kitchen and basement renovations were finished, we connected the new appliances and systems into the panel one by one. No surprises, no overloads – everything worked without a hitch.

Susan’s dream kitchen was fully powered, and the home theater lights didn’t even flicker when the AC kicked on. She joked that of all the upgrades in her renovation, the electrical panel was the one she’d never see (tucked away in the garage) but probably the most important. For anyone in Vienna or elsewhere thinking of a big remodel, Susan’s story shows why planning for a panel upgrade is so important. Better to have more capacity than you need, than to need it and not have it.

Future-Proofing in Reston – Preparing for an Electric Vehicle

A couple in Reston called me to discuss installing a charger for a new electric vehicle they were expecting to purchase in a few months. They lived in a 1980s-era home with a 100-amp electrical service. Their house was pretty typical – electric dryer, electric range, one HVAC system – and that 100-amp panel was handling the existing load okay, but there wasn’t much wiggle room. The moment they said “EV charger,” a little alarm bell went off in my head: those chargers can draw a substantial current (30-50 amps continuously for several hours when charging the car). On a 100-amp service, that might be like trying to add another full kitchen’s worth of demand – it probably wasn’t going to fly.

I visited their home and confirmed my hunch: they would likely overload their current panel if they added the EV charger without an upgrade. We discussed options, and they decided on a proactive approach: upgrade to a 200-amp panel now, and then install the EV charger. This way, they’d have peace of mind that the car charger (and anything else in the future) wouldn’t strain their system.

The panel upgrade in Reston went smoothly. We pulled the necessary permit from Fairfax County, coordinated with the utility for the service line upgrade, and installed a 200-amp panel in place of the old 100-amp. Then we ran a dedicated 240V circuit to the garage for a Level 2 EV charging station. When the couple got their new electric car, they were set up and ready to charge at full speed without tripping breakers.

A few months later, they emailed me to say thank you – apparently during a heat wave they had the AC, laundry, and EV charger all running simultaneously, and not a single breaker complained. Upgrading their electrical panel wasn’t just about the car; it gave them confidence that their home’s electrical system could handle whatever future tech they throw at it (they even started talking about maybe adding solar panels and a battery backup down the line). In fast-growing communities like Reston, I’ve seen a lot of homeowners take this future-proofing step. It’s a smart move if you’re eyeing new tech that will demand more from your home’s electrical system.

Preventing a Disaster in Falls Church – Replacing a Hazardous Old Panel

Not long ago, I was doing a small job (installing some light fixtures) at an older home in Falls Church. The house was built in the early 1960s and still had its original electrical panel. It was an old 100-amp Federal Pacific panel, and when I took a peek (as I always do when I’m in a customer’s home, out of habit), I got concerned. The panel was warm to the touch and I noticed some telltale signs of trouble: there was slight charring around one of the breakers and the wiring looked brittle. I gently mentioned to the homeowner, Mary, that her panel was in rough shape and possibly a fire hazard.

Mary was surprised – she’d lived there 30 years and never had a major issue, aside from the occasional tripped breaker. We talked about the notorious history of Federal Pacific (FPE) panels, how many of them have breakers that fail to trip during an overload, and how that can lead to overheated wires. I could see this was worrying news to her. She asked me what it would take to address it. My answer: a full panel replacement, sooner rather than later, to ensure her home’s safety.

After thinking it over (and reading up on FPE panel hazards, which I encouraged), Mary decided to go ahead with an upgrade. We scheduled a day to swap out the old panel for a new 200-amp one. The process was straightforward: I arranged for the power to be shut off in the morning, replaced the entire panel and any wiring that showed damage, and had power back on by late afternoon. We even added some extra circuits for her kitchen and workshop, since the new panel had space and she’d been juggling too many things on a couple of breakers before.

A week later, Mary left me a voicemail that still makes me smile. She said she felt like a weight was lifted knowing that old “ticking time bomb” in her basement was gone. She no longer worries when she runs the dryer and dishwasher at the same time. For anyone in an older home around Falls Church or Annandale or Springfield – take a glance at your electrical panel. If it’s an old brand known for problems, or just ancient in general, consider getting it checked. Mary’s story is a great reminder that preventive electrical upgrades can avert disasters.

Choosing Local in McLean – A Second Opinion Saves Money

In McLean, I met a homeowner named Alex who taught me just as much as I helped him. He called PRO Electric plus HVAC for a second opinion after another well-known company had given him an estimate for a panel upgrade. (I won’t name names, but let’s just say it was one of those big outfits like Michael & Son.) Alex’s home was a spacious 1980s colonial that still had the original 150-amp panel. He wasn’t experiencing major issues yet, but he was planning to install a backup generator and figured an upgrade to 200 amps made sense. The first company had quoted him a price that frankly made my jaw drop – it was several thousand dollars higher than what I would typically charge for a similar job. They also recommended some additional work that Alex wasn’t sure he actually needed.

When I came out to his McLean property, I did a thorough assessment. Indeed, to hook up a decent-sized generator and keep everything up to code, a 200-amp service upgrade was the right call. But I assured Alex that the job was straightforward and that his existing wiring was in good shape, with no signs of the issues that would merit the extra add-ons he was quoted for. I believe in transparency and not selling something just to sell it – a philosophy that sets us apart from some larger competitors. I gave Alex an estimate that was far more reasonable, and I took the time to answer all his questions (he had a lot, which I respect!).

He decided to go with us. We upgraded his panel to 200 amps, installed the transfer switch for his future generator, and got everything inspected and approved without any hiccups. After the project, Alex told me that working with a local company felt different: “You explained everything, did exactly what you promised, and there were no surprise costs. I felt like I was working with a neighbor, not a salesman.” That was music to my ears because it’s exactly the experience I want for every customer.

Alex’s story highlights something important: whether you live in McLean, Great Falls, or anywhere in Fairfax County, it pays to get a second opinion and to trust a local expert. Bigger companies like Kolb Electric or Michael & Son might have big advertising budgets, but bigger isn’t always better when it comes to customer service and fair pricing. Many of my happiest clients are those who chose the personal touch of a local pro over a faceless corporation.

How Much Does an Electrical Panel Upgrade Cost?

Cost is always an important question. As a homeowner myself, I get it – you want to know what kind of investment you’re looking at. The honest answer is it depends on the specifics of your home and what exactly needs to be done. But I can certainly give you a general idea and explain the factors.

Typical Price Range: In Fairfax County, a standard 200 amp electrical panel upgrade (replacing an older panel and upgrading the service) can typically range from around $1,500 to $4,000 for most homes. I’ve done simpler upgrades on small townhouses in Burke for maybe around the lower end of that range. And I’ve handled more complex heavy-ups in large homes in Great Falls that went toward the higher end or a bit beyond. Most jobs fall somewhere in the middle. If someone is giving you a quote way above or below that range, be sure to ask why – scope and quality can vary.

What Factors Into the Cost? Several things:

Panel Size & Ampacity: Upgrading to 200 amps is standard, but if you have an unusually large home or special requirements (say you wanted a 400-amp service for a huge house or multiple sub-panels), that changes things.
Existing Condition: If your current panel is very old or in bad shape, there might be extra work to safely remove it (especially if there’s damage, like burn marks or melted wires). Similarly, if your panel is in a tough-to-access spot or if we find other issues (like outdated wiring that should be replaced at the same time), that can affect cost.
Service Cable and Meter: Often, a service upgrade means we need to replace the main service cable and possibly the meter box. That’s usually included in the cost range above, but it’s a factor. Sometimes the feed from the utility (like the line from the pole to your house) needs upgrading – we coordinate with Dominion Energy for that, but they handle their part of the work.
Permits and Inspection: In Fairfax County, an electrical permit and inspection are required for a panel replacement or service upgrade. There’s a cost for the permit (which is usually a small fraction of the total) and a bit of time needed to schedule inspections. As a licensed contractor, I handle all of this for you, but it’s part of the overall project scope.
Emergencies or After-Hours Work: If your panel upgrade is done as an emergency (like the Fairfax story I shared earlier where we had to work overnight), there might be some additional cost due to the urgency and off-hours labor. I try to be fair about this – no one plans to have an emergency, and I don’t believe in exploiting a bad situation – but bringing out a crew at 2 AM does cost more than doing work on a Tuesday afternoon.
Extras and Upgrades: Sometimes homeowners decide to add other electrical work during a panel upgrade (for example, adding surge protection for the whole house, or installing new circuits for future use). Those will add to the cost accordingly, but they’re optional. I usually will mention these as suggestions if I think they add safety or value, but I’m not going to pile on extras you don’t need.

Transparency and Trust: I’ve heard the horror stories of people getting quoted one price and then being hit with “surprise” charges once the work starts. That’s not how we operate. When I give you an estimate for a panel replacement or service heavy-up, it’s clear and itemized. If there’s any possibility of an unknown (like “we may need to replace some old wiring if we find it’s unsafe”), I tell you upfront and give a worst-case scenario price so you’re not left in the dark (pun intended).

Also, we offer free estimates. If you’re even contemplating an electrical panel upgrade, I’m happy to come out and take a look. I can usually tell pretty quickly what we’re dealing with and give you a ballpark number on the spot, followed by a written estimate. No pressure, no obligation. Knowledge is power (literally, in this case).

Financing Options: I know an unforeseen panel upgrade can strain the budget. To help, PRO Electric plus HVAC offers financing options, including 0% interest plans for qualified homeowners. This means you could spread out the cost of your new panel over 12 months without paying a dime of interest. I mention this because I don’t want anyone to delay a needed safety upgrade purely due to cost. We’ll work with you to make it as affordable as possible.

Remember, an electrical panel upgrade isn’t just an expense – it’s an investment in your home’s safety and functionality. It can even boost resale value and make your home more attractive to buyers (many buyers in places like Reston or Fairfax specifically ask if the electrical system is updated). And when you consider the peace of mind you get, it’s worth every penny. Next, I’ll walk you through what actually happens during a panel upgrade, so you know what to expect if you decide to move forward.

What to Expect: Our Electrical Panel Upgrade Process

If you’re considering moving forward with a panel upgrade, you might wonder what the process looks like. I find that knowing the steps ahead of time helps homeowners feel more comfortable. So, here’s a quick rundown of how a typical electrical panel upgrade or replacement goes when you work with PRO Electric plus HVAC (don’t worry, we handle all the heavy lifting – literally and figuratively):

Initial Consultation & Assessment: It starts with me (or a member of my team) coming out to your home to inspect your current panel and discuss your needs. We’ll listen to any concerns you have (breakers tripping, plans for new appliances, etc.), take a look at the panel, and evaluate the overall electrical setup. This is when we determine if an upgrade is needed and to what extent (100 to 200 amps, sub-panel additions, etc.). We’ll also answer all your questions. This visit is usually free of charge.
Detailed Estimate: After the assessment, you’ll get a clear, written estimate. It will outline the scope of work – for example, “Replace existing 100-amp panel with new 200-amp panel, upgrade service entrance cable, install new ground rods, etc., permit and inspection included.” You’ll see the cost breakdown, so you know exactly where your investment is going. If anything is optional (like adding surge protection or a generator interlock), it’ll be noted separately. No surprises.
Scheduling the Work: Once you give the green light, we schedule the upgrade at a time convenient for you. If it’s not an emergency situation, we typically plan for a day when you can be home (since the power will be off for several hours) and when it’s not terribly inconvenient (nobody wants their fridge off on a 100°F day for long, for instance). We also handle pulling the necessary permit from Fairfax County at this stage.
Preparation & Utility Coordination: Before the day of work, we coordinate with the power company (Dominion Energy or NOVEC, depending on who services your area) to disconnect power on the morning of the job. Sometimes the utility will send a tech to pull the meter or disconnect the line. We time it so that as soon as they disconnect, we get to work.
Out with the Old, In with the New: On installation day, we start early. First, we ensure all power is off and double-checked. Then we carefully remove the old panel. If this is a service upgrade, we’ll also replace the service cable and install a new meter box (if needed). Next, we mount and install the new panel. One by one, we move circuits from the old to the new, replacing any old breakers with new ones and labeling everything clearly. If any of the existing wiring isn’t long enough to reach the new panel layout, we safely splice and extend it within code guidelines (using junction boxes as needed).
Safety and Quality Checks: Once the new panel is in place and all the circuits are connected, we double-check all connections, torque down every screw and lug properly, and test the installation (with power still off). Safety is huge – I personally ensure every screw is tight, every wire is landed correctly. We also install proper grounding and bonding as required by code (for example, connecting the panel to your home’s grounding rods and water pipe if applicable).
Inspection: After we’re satisfied internally, we schedule the official county inspection (if it’s the same-day inspection, sometimes they come that afternoon; other times it’s the next day – in which case we arrange temporary power if needed). The inspector will come and basically ensure that the work meets all code requirements. I’m proud to say our work passes inspections the first time almost every time. Being familiar with Fairfax County electrical codes and inspectors’ expectations pays off here.
Power On!: Once we have the go-ahead from the inspector, the utility will restore power (either by us plugging the meter back in or the utility re-connecting the line). Now your shiny new panel comes to life. We go through and test some of the circuits with you, just to show that everything is working as it should. Lights on, appliances humming – all systems go.
Cleanup & Wrap-up: We don’t leave a mess. We’ll dispose of the old panel and any debris. I often have homeowners comment that they couldn’t even tell we had such major work done except for the new panel sitting there. After cleanup, I walk you through the new panel. I show you which breakers control what (and make sure they’re labeled clearly), explain any new features (like if we installed a whole-home surge protector or a generator interlock switch), and answer any final questions.
Follow-Up: Just because the job is done doesn’t mean we disappear. I usually follow up within a week to ensure all is well. And of course, if you ever have questions afterwards, I’m just a phone call away. The panel comes with a manufacturer warranty, and our workmanship is guaranteed. If something isn’t right (rare, but hey, we’re all human), we make it right.

I know that was a lot of detail, but many people have never gone through a panel replacement before, and it helps to demystify it. The bottom line: we take care of everything from start to finish – permits, utility coordination, the works. Your job is just to sit back (perhaps take that day as an opportunity for a family outing while we work) and look forward to a safer, stronger electrical system in your home.

Next up, I want to talk about why choosing a local expert for this job really matters, and how PRO Electric plus HVAC stands out from the crowd.

Why Local Expertise Matters in Fairfax County

Fairfax County isn’t just anywhere – it has its own building codes, permit processes, and common construction practices. Hiring a local electrician who knows the area can make a world of difference for a project like an electrical panel upgrade. Here’s why working with someone who’s deeply familiar with Northern Virginia (NoVA) is so important:

Knowledge of Local Codes: As a Northern Virginia electrician, I stay up-to-date with both the National Electrical Code (NEC) and specific Fairfax County amendments or requirements. For example, Fairfax might have particular rules about surge protection or outdoor disconnects that a less experienced or out-of-area electrician might overlook. Because I pull permits regularly here, I know what the county expects, which means smoother approvals and no failed inspections due to “rookie” mistakes.
Permit & Inspection Process: Every jurisdiction has its way of doing things. I’ve been dealing with Fairfax County’s permit office and inspectors for years. I know many of them by name. This rapport means I can often schedule inspections faster or get questions answered promptly. If you were to hire a company from far out of town, they might not even know who to call or how to navigate our local system as efficiently.
Understanding Home Styles: Homes in McLean or Great Falls can be quite different from homes in Fairfax City or Centreville. We have everything from 1940s brick ramblers to 1990s suburban two-stories to modern high-tech homes. I’ve worked in all of them. That means I’m familiar with common wiring setups and potential quirks. For instance, many homes built in the 60s around Annandale and Springfield have aluminum branch circuit wiring – which affects how we handle connections during a panel change. A local expert has the context to anticipate these things.
Quick Response & Availability: Being local means I can get to you faster in case of an urgent need. If a storm knocks out power or you have an emergency panel issue in the middle of the night in Fairfax County, I’m not driving three hours to get here – I’m likely just a short hop away. PRO Electric plus HVAC is based right here in the community (our office is in Fairfax), so we can offer genuinely fast emergency service.
Community Trust: This isn’t just business for me – it’s personal. My kids go to school here, my family shops at the same grocery stores as yours, and our company has deep roots in the community. When I do a panel upgrade for a neighbor, I know that I’ll probably bump into them at the hardware store or the next local festival. That’s a great motivator to do excellent work! Our reputation in Fairfax County means everything, so we go the extra mile. In contrast, I’ve heard stories of fly-by-night operators or out-of-area contractors doing shoddy work and then disappearing. That’s never a worry with a truly local pro who’s here to stay.
Supporting Local Economy: Choosing a local small business means your dollars stay in the community. It helps employ local technicians and support local families (like mine and those of my crew). There’s a pride in local workmanship – when you drive by a home and can say, “I helped make that place safer,” it feels good.

In short, when you go with a local expert like PRO Electric plus HVAC for something as critical as an electrical panel upgrade, you’re getting someone who knows the territory (literally and figuratively). You’re getting the benefit of experience that’s tailored to Fairfax County’s unique needs and regulations. And you’re supporting a neighbor.

Now, beyond just being local, let me highlight some specific reasons why PRO Electric plus HVAC is the go-to choice for many homeowners looking for quality electrical work.

Why Choose PRO Electric plus HVAC for Your Panel Upgrade?

I know, I know – I’m a bit biased here. But I truly believe my team offers something special. Plenty of companies can technically swap out a panel for you, but with PRO Electric plus HVAC, you get more than just technical skill. You get a partner who actually cares about you and your home. Here are a few reasons homeowners across Fairfax County choose us (and keep referring us to friends and family):

Experience & Expertise: I’m a Master Electrician with decades of experience. I started PRO Electric plus HVAC after years of working for larger outfits because I knew I could deliver better service on my own terms. My crew consists of seasoned, licensed electricians (and HVAC techs) who have seen it all. Whether it’s a straightforward 200-amp upgrade or a complex overhaul in a historic home, we have the know-how to do it right. We’ve successfully completed countless electrical panel upgrades for families in Fairfax, Vienna, Oakton, and beyond.
All-in-One Service: As our name implies, we handle both electrical and HVAC. Why does that matter for your panel upgrade? Well, if you’re upgrading your electrical service to, say, accommodate a new electric heat pump or AC system, you’re dealing with a team that understands the whole picture. We can coordinate between the electrical work and HVAC needs seamlessly. It’s one less headache for you.
No Upselling, Just Honesty: Unfortunately, in the home service world, some companies train their techs to upsell everything under the sun. That’s not our style. If your panel is fine and you don’t need an upgrade, I’ll tell you straight up. If you do need one, I’ll explain exactly why and what your options are. But I’m not going to push fancy gadgets or additional services you don’t truly need. Many of my customers in Reston and McLean have told me they appreciate that refreshing honesty after experiences with other companies.
Personal Attention: When you hire PRO Electric plus HVAC, you get personal attention from the owner (hi, that’s me!) and a small, dedicated team. You’re not just a job number in a massive corporate system. I take pride in personally overseeing most big jobs like panel upgrades, or at least being in close contact with my lead electrician on site. If you have questions or concerns, you can reach out to me directly. That’s something larger companies like Kolb Electric or Michael & Son might not offer – with them, you might just get whichever technician is on call that day. With us, you get continuity and a familiar face.
Proven Track Record: We stand behind our work. Our customers’ reviews speak volumes – we’re highly rated on Google, Yelp, and community boards. (Last time I checked, we had over 500 five-star reviews!) We’ve earned those by treating customers right and delivering quality. When it comes to something as important as your home’s electrical panel, you want to know it’s done by folks who do it right. Our track record in Fairfax County shows you can count on us.
On-Time and Professional: It might sound basic, but we show up when we say we will. And we respect your home – that means wearing boot covers indoors, laying down mats if we need to walk through with equipment, and cleaning up thoroughly after ourselves. We’ve all heard about the contractor who vanishes for days or leaves a mess – that’s not going to happen with my team. We treat your home as if it were our own.
Licensed and Insured: This should be a given, but I’ll mention it because it’s vital. We are fully licensed electricians in Virginia and carry proper insurance. You’d think every electrician advertising services is licensed, but you’d be surprised – some aren’t, or they cut corners by using apprentices unsupervised. With PRO Electric plus HVAC, you’re getting legitimate, professional service. This ties back to our focus on safety and code compliance – no shortcuts.
Fair Pricing: We talked about cost earlier. We strive to offer fair, competitive pricing for our work. We’re not the cheapest out there (and honestly, you probably wouldn’t want “cheap” when it comes to electrical work), but we’re also not going to gouge you. Because we’re a local business with lower overhead than some big franchises, we often can give better prices while still using top-quality materials. It’s the best of both worlds – high quality and fair value.
Customer Education: I genuinely enjoy educating my customers (hence pages like this one!). During a panel upgrade, I’ll keep you informed about what we’re doing in layman’s terms. I’ve found that homeowners appreciate understanding the work happening in their home. And if you’re curious and want to watch how we do things, I’m more than happy to explain as we go (safely, of course). It’s your home, and you have a right to know what’s being done.
Follow-Up and Support: After the work’s done, we don’t just forget about you. I stand by our upgrades with a solid warranty. If you have an issue or even just a question down the road (“Hey, Peter, I’m adding a freezer in the garage, am I good to go?”), I’m here to help. This is a relationship, not a one-and-done transaction.

Ultimately, our goal is to make you so satisfied that you’ll call us for any electrical (or HVAC) needs in the future and feel confident recommending us to neighbors. That’s how a local business like ours thrives – by building trust one job at a time.

When you choose PRO Electric plus HVAC, you’re choosing peace of mind, quality workmanship, and a friendly team that truly values your business. We want to be the best decision you’ve made for your home.

Alright, I’ve bent your ear enough about us. Now, let’s answer some common questions homeowners often have about panel upgrades.

FAQs about Fairfax County Electrical Panel Upgrades

Q: How do I know if I need a full panel upgrade or just a minor fix?

A: Great question. Sometimes a problem can be resolved with a minor repair (like replacing a single bad breaker or tightening some connections) rather than a full electrical panel replacement. If you’re only having issues on one circuit (for example, one breaker trips occasionally) and your panel is modern and in good shape, it might not need an overhaul. However, if you’re experiencing multiple symptoms – flickering lights, many breakers tripping, or you know your panel is old – it’s likely pointing to a need for an upgrade. I always start with an inspection. I’ve told homeowners in Fairfax before that all they needed was a $50 breaker replacement, not a whole new panel. Other times, it’s clearly a bigger issue. So, it depends, and that’s why an honest assessment is key.

Q: How long does it take to upgrade an electrical panel?

A: Most residential panel upgrades (e.g., going to 200 amps) can be done in a day. Typically, we’ll cut power in the morning, work through the day, and have your new panel up and running by late afternoon or early evening. There are cases that might take longer – for instance, if we discover unforeseen issues (like a bunch of wires in really bad shape that need replacing) or if we’re also doing other upgrades simultaneously. But for the vast majority of homes in places like Herndon or Vienna, it’s a one-day job. We always plan so that you’re not without critical power overnight. And remember, we coordinate with inspectors and the utility to minimize downtime.

Q: Will I need to rewire my whole house when upgrading the panel?

A: No, you shouldn’t need to rewire the whole house just for a panel upgrade. A panel upgrade will tie into your existing house wiring. We’ll move all the existing circuit wires from the old panel to the new one. As long as your existing wiring is in decent condition and was safe before, it remains as is. That said, if we notice something dangerous (say, a wire with damaged insulation or an old unsafe connection), we’ll fix that localized issue while we’re there. But we’re not tearing open your walls or rewiring all your outlets – not unless you want us to as a separate project. The focus is on the panel and the service connection. If you have an older home in Annandale or Burke with cloth-insulated wiring or aluminum wiring, we may recommend some improvements or at least special connectors, but that’s case-by-case and we’ll discuss it with you.

Q: Does a 200-amp upgrade increase my electricity bill?

A: Nope. Upgrading your service to 200 amps does not itself increase your energy usage or bill. Think of it like increasing the size of a water pipe – it doesn’t force more water through, it just allows more to flow if needed. Your usage (how many lights or appliances you run) is what drives your bill. The panel just needs to be capable of delivering what you ask of it. If after upgrading you do end up adding more devices (like that EV charger or electric heater), then your usage could go up and so would your bill – but that’s because of the new devices, not the panel itself. The panel is just “future-proofing.” I tell my customers in Reston and Oakton that a bigger panel is like having the headroom for future needs; it doesn’t cost you anything extra to have that headroom.

Q: Should I upgrade my electrical panel before installing solar panels or a backup generator?

A: It’s a smart idea to evaluate your panel before those installations. Solar panel systems and backup generators both tie into your electrical panel. If your panel is old or maxed out, you might need an upgrade or at least a sub-panel added. For solar in Fairfax County, the installer will often require you to have a modern panel with space for a solar breaker. I’ve worked with some homeowners in Centreville and Fairfax Station who did a panel upgrade as part of their solar panel installation process. Similarly, for a backup generator, you’ll need a proper transfer switch and your panel must be compatible. Upgrading to 200 amps can ensure your generator can power the whole house (if it’s sized for it) and that everything is wired safely. When in doubt, I can assess your current setup and let you know if an upgrade would benefit your solar/generator plans.

Q: What about adding a sub-panel vs. upgrading the main panel?

A: Sometimes, if your main panel is in good shape and has sufficient amperage (say it’s already 200 amps), but you’re simply out of breaker spaces, we might add a sub-panel instead of replacing the whole main panel. A sub-panel is like a satellite breaker box that gives you more circuits. For example, if you’re adding a big addition to your McLean home, we might leave your existing 200-amp panel as is and just add a 100-amp sub-panel in the new addition to handle the extra circuits. Sub-panels are also common when garages or workshops are added. They’re a cost-effective way to expand capacity without changing the service. However, if your main service is undersized (like 100 amps) or the panel is old/unsafe, then upgrading the main panel is the way to go. We’ll advise on what’s best for your situation.

Q: Can I perform a panel upgrade myself or have a handyman do it to save money?

A: I strongly advise against DIY or using someone unlicensed for this. An electrical panel upgrade is one of those projects that requires a permit and a licensed electrician by law (for good reason). There’s a lot that can go wrong – from improper connections that could cause a fire down the line, to the immediate risk of electrocution if someone doesn’t know exactly what they’re doing. I’ve had a few homeowners call me after a “handyman” botched a panel replacement, and it ended up costing more to fix the mistakes. Save yourself the risk and likely extra expense; have a certified professional do it right the first time. Plus, only a licensed contractor can get the necessary permit and coordinate with the power company for the disconnect/reconnect. Your safety is worth it.

Q: Will a new electrical panel make my home safer?

A: Absolutely. A new panel means new, tight connections; breakers that reliably trip when they should; and up-to-date safety features. If you’re replacing a panel that was a known hazard (like the old FPE or Zinsco panels we talked about), you’re eliminating a major fire risk. Even if your old panel was just aged, not outright defective, having a new one reduces the chance of things like overheating, arcing, or failing breakers. It’s like the difference between driving a car with worn-out brakes versus one with brand new brakes – both might stop the car, but one is clearly safer. Many homeowners in Springfield and Falls Church have told me they feel peace of mind knowing there’s a modern, safe panel at the helm of their electrical system after we upgrade it.

Q: I’ve heard that Federal Pacific (FPE) or Zinsco electrical panels are fire hazards. Is that true?

A: Unfortunately, yes, there’s truth to that. Federal Pacific Electric (FPE) panels with Stab-Lok breakers, as well as Zinsco brand panels, have a long-documented history of problems. Studies found that a significant percentage of FPE breakers failed to trip during an overload or short-circuit condition, which means they can let dangerous currents flow unchecked – a major fire risk. Zinsco panels have their own issue: the breaker-to-bus bar connections can degrade and cause arcing and overheating. In my experience around Northern Virginia, whenever we come across these panels (mostly in houses from the 1960s and 1970s in areas like Springfield, Falls Church, or Annandale), we strongly recommend replacing them. In fact, many home inspectors will flag these during home sales. If your home has one of these outdated panels, upgrading to a new, safe panel is one of the best improvements you can make for your peace of mind. It’s a common project for us here at PRO Electric plus HVAC – we’ve swapped out many FPE and Zinsco panels across Fairfax County.

Q: Does an electrical panel upgrade add value to my home?

A: In many cases, yes. While it might not be as flashy as a kitchen remodel, an updated electrical system is a big selling point. Think about the savvy buyers (and home inspectors) in our area – they often ask about the age of the roof, the HVAC, and the electrical system. If you can say, “The home has a new 200-amp electrical panel and updated service,” that’s a green flag for buyers. It means one less major thing they’ll have to worry about. I’ve worked with some clients in Falls Church and Alexandria who proactively upgraded panels before listing their homes on the market. They reported that it not only made their home more attractive to buyers, but in a couple of cases, it actually helped the sale go through without a hitch (no haggling over electrical issues in the home inspection). So, while an electrical upgrade is first and foremost about safety and functionality, it can indeed add to your home’s value and marketability.
