Electrical panel upgrades aren’t something people think about every day, and honestly, most folks don’t even open the door to their panel unless a breaker trips or they hear a strange sound coming from inside. But as a master electrician who’s worked all over Fort Myers—from older homes along McGregor to newer builds in Gateway—I can tell you this: your electrical panel is the heart of your entire system. And when the heart starts struggling, everything else does too.
We meet homeowners and business owners all the time who say things like:
“Every time the AC kicks on, the lights dim.”
“We added a new appliance and the breaker won’t stay on.”
“The panel is full—there’s nowhere to add anything.”
“We bought an EV and the electrician said the panel can’t handle it.”
“This panel looks old… do we need to replace it?”
And in Fort Myers, there’s another major factor: humidity and storms. Electrical panels here take a beating from moisture, heat, and lightning activity. You’d be surprised how many panels we open that have rust creeping in, loose connections from expansion and contraction, or breakers that are so worn down they barely hold tension.
Upgrading a panel isn’t just about modern convenience—it’s about safety, reliability, and making sure your electrical system can handle the demands of today’s technology.
At Coharbor Electric, we upgrade electrical panels the right way—not rushed, not sloppy, not “just enough to pass.” We upgrade them to last.
Fort Myers is unique in ways that really matter electrically. The environment here works against panels more than homeowners realize:
Humidity:
Panels in garages or on exterior walls absorb moisture year-round. Even tiny amounts build up into corrosion.
Storms:
Frequent lightning strikes weaken breakers and internal components over time.
Heat:
Panels exposed to constant heat expand and contract, loosening connections.
Aging construction:
Many Fort Myers neighborhoods—from Cypress Lake to San Carlos Park—still have panels from the 70s, 80s, and 90s.
Modern appliances and electronics:
A 100A or even 150A panel wasn’t designed for tankless water heaters, EV chargers, high-efficiency HVAC systems, outdoor kitchens, and home offices full of electronics.
Home additions without proper electrical upgrades:
We see this constantly. A home gets a bedroom added on, a lanai enclosed, a garage converted—but nobody ever upgraded the panel.
All of this leads to a panel working far harder than it was built for. And when a panel is pushed too hard, that’s when we start seeing the warning signs.
Here are the real-world clues we see every week:
• Breakers tripping often
This isn’t “just how breakers work”—it’s a panel telling you it’s overloaded or failing.
• Flickering lights or dimming under load
If the lights dip when the AC starts or a microwave runs, your panel may not be keeping up.
• A warm or buzzing panel
Panels shouldn’t make noise or feel warm. That’s a red flag.
• Rust, corrosion, or discoloration
Humidity is sneaky; once rust starts, it spreads.
• A burning smell or popping sound
These are serious warnings—don’t ignore them.
• You’ve run out of breaker spaces
We see maxed-out load centers all the time.
• Your insurance company flags your panel
Some panel brands are known hazards.
• Upgrading appliances or adding circuits
A tankless heater or an EV charger alone can demand more power than your entire home originally did.
• You’re planning a remodel or addition
This is the best time to upgrade—before the drywall goes up.
If any of these sound familiar, a panel upgrade is likely the safest long-term solution.
A lot of people imagine a panel upgrade as simply pulling out the old metal box and snapping in a new one, but as a master electrician, I’ll tell you—it’s far more detailed than that.
Here’s how we handle panel upgrades at Coharbor Electric:
1. Evaluate the current system load
We look at what you’re running now and what you plan to run in the future.
2. Choose the right panel size
Most Fort Myers homes benefit from a 200A panel, but commercial properties or larger homes may need even more.
3. Remove the outdated or unsafe panel
We frequently replace Federal Pacific, Zinsco, Challenger, and early Square D models.
4. Upgrade grounding and bonding
Florida soil and humidity make grounding even more critical here.
5. Install the new panel cleanly and carefully
We route wires neatly, secure everything properly, and avoid the “spaghetti mess” many old panels suffer from.
6. Re-label every circuit accurately
A properly labeled panel makes every future service faster and safer.
7. Add whole-home surge protection
This is essential in Fort Myers due to lightning and grid fluctuations.
8. Ensure code compliance
We follow NEC standards, Fort Myers building codes, and Lee County regulations.
9. Coordinate with the utility for service reconnection
No stress on your end—we take care of all scheduling and logistics.
When the upgrade is complete, your system doesn’t just work better—it’s safer, cleaner, and built to last for decades.
We upgrade panels in all kinds of buildings, including:
Homes (old and new)
Condos & townhomes
Retail stores
Restaurants
Offices
Warehouses
Industrial units
Rental properties
Vacation homes
Multi-unit buildings
Areas we frequently service include:
McGregor Blvd
Colonial Blvd
Daniels & Treeline/Gateway
Cypress Lake & Whiskey Creek
San Carlos Park
Three Oaks
Downtown Fort Myers
Iona & Winkler
North Fort Myers
Each area has its quirks. Older McGregor homes have layered remodels. San Carlos Park has panel failures caused by moisture and aging wiring. Downtown buildings usually need capacity upgrades. And the Treeline/Gateway corridor sees more EV charger installations than almost anywhere else.
Wherever you are, we’ve probably upgraded a panel near you.

A family in the Whiskey Creek area reached out because their breakers were tripping constantly, especially when the dryer and AC ran at the same time. They were tired of flipping breakers and worried something was wrong.
When we arrived and opened the panel, here’s what we found:
A full, outdated 100A panel
Multiple double-tapped breakers
Corrosion and moisture from years of garage exposure
A grounding system far below modern standards
Heat damage around the main breaker
Mixed wiring from past additions
It was a perfect example of a panel doing more than it was ever intended for.
We upgraded them to a new 200A panel, cleaned and organized every circuit, corrected unsafe wiring, added surge protection, upgraded grounding, and ensured everything was code-compliant.
The homeowner told us afterward,
“Everything runs smoother… we didn’t realize how stressed the system was until now.”
That’s exactly what a proper panel upgrade does—restores stability.
Q: How do I know what size panel I need?
We evaluate your load and ask about future plans—EVs, remodels, appliances, etc.
Q: Does a panel upgrade increase home value?
Absolutely. It’s one of the strongest electrical upgrades you can make.
Q: Will the power be off during installation?
Yes, but only during the actual panel swap—we work efficiently.
Q: Do you upgrade wiring too?
If wiring is outdated or unsafe, yes—we address it during the upgrade.
Q: Do you install surge protection?
Yes. In Fort Myers, we consider it essential.
If your panel is outdated, overloaded, unsafe, or just not keeping up with your home or business anymore, we’d be glad to help.
