Electrical Upgrade Options for Fort Myers Homes | CoHarbor Electric

Not every homeowner who calls us wants a smart panel or an app that tells them what their AC is doing. A lot of folks just want their house to work the way it should — enough outlets where they actually need them, a panel that isn’t maxed out, breakers that don’t trip for no reason. Had a homeowner out in Tanglewood tell us flat out, “I don’t need to control my lights from my phone, I just want to plug in my toaster and my coffee maker at the same time without flipping a breaker.” Fair enough. That’s most people, honestly.

So this one’s for the practical upgrades — the ones that don’t show up in a smart-home ad but make a real difference in how a house actually functions day to day.

Panel Capacity: The Upgrade That Enables Everything Else

Before any other upgrade on this list makes sense, the panel has to be able to support it. A lot of Fort Myers homes — particularly older ones in areas like Villas and Cypress Lake — are still running on 100-amp service that was perfectly fine decades ago and is genuinely tight today. Add a second AC unit, a pool pump, maybe an EV charger down the line, and 100 amps stops having any real margin.

We run a load calculation under NEC Article 220 before recommending anything here — not a guess based on square footage, actual numbers. For most Fort Myers homes today, 200 amps is the standard recommendation, and it’s usually paired with a panel that has more circuit slots too, which solves both the amperage problem and the “there’s no room for another breaker” problem at the same time.

Wiring Updates: Fixing What’s Actually There

If your home was built between roughly 1965 and 1973, there’s a real chance some of the wiring is aluminum rather than copper. It’s not an automatic emergency, but aluminum connections loosen at the terminal in a way copper doesn’t, and that’s where heat builds over time. We check for this specifically in homes from that era — we’ve found it more than once in older sections of Six Mile Cypress and Olga.

For homes where the wiring’s fundamentally sound but a few circuits are undersized or overloaded — say, a kitchen running on the same circuit as half the rest of the house — targeted rewiring of just those circuits is often enough. You don’t always need a full rewire to fix a real problem. Sometimes it’s a handful of circuits that need updating, not the whole house.

Outlet Upgrades: More Than Just Adding More of Them

Older Fort Myers homes frequently have too few outlets for how people actually live now — everyone’s got more devices than the house was built to accommodate. But adding outlets is only half of it. Under NEC Article 210, kitchens, bathrooms, garages, and outdoor spaces need GFCI protection, and a lot of homes still have standard outlets in those locations, sometimes with a three-prong plug swapped in over an ungrounded two-prong circuit — which looks fixed but isn’t actually grounded.

AFCI protection is worth mentioning too. It’s increasingly required on circuits serving bedrooms and living spaces, and it protects against a different kind of hazard than GFCI does — arc faults, which GFCI protection doesn’t catch. If you’re updating outlets anyway, this is the moment to bring those circuits up to current code rather than just adding more of the same.

Whole-Home Surge Protection

Florida’s storm season means power surges are a regular occurrence here, not a rare event — lightning strikes near the grid, FPL switching operations during outages, the electrical equivalent of a jolt every time the power blinks. A whole-home surge protector installed at the panel catches these before they reach anything plugged into your walls, which matters a lot more than the point-of-use surge strips most people rely on for a TV or computer. Those strips protect one device. A panel-level surge protector protects everything at once.

GFCI and AFCI Breaker Replacements Without a Full Remodel

You don’t need to be mid-renovation to update your protection. If your panel’s original and never had GFCI or AFCI breakers added, we can often swap individual breakers to add that protection without opening walls or doing any invasive work. It’s one of the more cost-effective safety upgrades available, and it’s a good candidate for homeowners who want meaningful improvement without a big project.

Common Mistakes We See With These Upgrades

Adding outlets without checking the circuit they’re on. More outlets on an already-loaded circuit just means more things competing for the same limited capacity.

Assuming three-prong outlets mean the circuit is grounded. It’s an easy assumption, and it’s wrong more often than people expect in older homes.

Skipping the load calculation before adding load. Whether it’s more outlets, an appliance upgrade, or anything else pulling more power, guessing at capacity instead of calculating it is how panels get pushed past what they can handle.

Treating surge protection as optional. In a region that sees the storm activity Fort Myers does, panel-level surge protection is one of the more overlooked upgrades — and one of the more affordable ones relative to what it protects against.
