Duke Energy's grid switches during a storm. The lights flicker. Nothing looks damaged. Three months later, your AC's control board is dead and nobody can tell you why.
That's a surge doing its job of ruining your equipment quietly. Clearwater sits in one of the highest lightning-density regions in the country, so this isn't a rare event — it's a Tuesday.
Why this matters more here than in most places
Two things stack against Clearwater homes specifically: frequent lightning activity, and a grid that reroutes power during storms more often than inland areas see. Every reroute is a small voltage spike. Most don't kill anything outright. They shave a little life off your HVAC control board, your refrigerator's digital panel, your pool pump — the same way running an engine hot doesn't blow it up today, but it will eventually.
Signs a surge has already done damage
Most homeowners don't connect these to power surges because nothing looked dramatic when it happened:
- An AC that suddenly won't turn on, with no error code and no obvious mechanical issue
- A smart thermostat that resets itself or loses its schedule for no reason
- Appliances with digital displays that glitch, freeze, or show random symbols
- A breaker that trips more often than it used to, without a clear cause
None of these prove a surge caused it. But if you've had two or more of these in the same year, especially after a storm, a surge is a more likely explanation than most people assume.
What a whole-home unit actually protects
Not everything, and that distinction matters. A whole-home surge protector:
- Stops the surge at your electrical panel, before it spreads to your wiring.
- Protects hardwired systems — your AC, water heater, oven — that a plug-in strip never reaches.
- Does not protect against a direct lightning strike. Nothing fully does. What it does is absorb the more common grid-level surges that cause the slow, cumulative damage.
- Typically lasts around five years of normal use, less if your area sees frequent surge activity. It's not a "set it and forget it forever" device.
That last point is one most companies won't tell you, because it's easier to sell "lifetime protection." It isn't that. Plan on having it checked, not just installed and forgotten.
Where it fits with what you already have
If you've got a power strip on your TV or computer, keep it — it's your second line of defense for the electronics plugged into it. A whole-home unit at the panel is your first line, and it's the only one that reaches equipment that isn't plugged into anything, like your HVAC system. One without the other leaves a gap.
What installation looks like
A licensed electrician evaluates your panel, sizes the protector to your home's load, and hard-wires it in — usually in 1-2 hours. This isn't a project for a general handyman or a DIY weekend; working inside a live service panel without the right training is how people get hurt. Our electricians hold Florida license EC13015085 and handle the permit and inspection side so you're not chasing paperwork afterward.
What it costs versus what it saves
A whole-home surge protector installation typically runs a few hundred dollars, depending on your panel's condition and home's electrical load. Compare that to a single HVAC control board replacement, which alone can run into four figures — and that's before counting the refrigerator, water heater, or pool equipment a bad surge can take out in the same event. It's not a guarantee nothing ever fails again. It's a way to stop paying for the same kind of damage repeatedly.
If you're deciding whether it's worth it
It's most worth it if you've already had a surge-related repair, if your home has a pool system or smart thermostat, or if you just want one less thing to worry about every time a storm rolls through. It's less urgent if your panel is brand new and you've never had an issue — though most electricians would still call it cheap insurance against a five-figure appliance replacement bill.

No — think of it as reducing how often you need to file a claim in the first place, not a substitute for coverage.
No. This work happens inside a live main panel, and Florida code requires a licensed electrician for the installation and permitting.
No — a surge protector doesn't keep the power on during an outage. That's a separate conversation about generators or battery backup.
Look at your main panel for a small module wired directly into the breakers, usually with an indicator light. If you're not sure, it's a five-minute check for an electrician — easier than guessing and finding out the hard way during the next storm.
Depends on the size of the surge. Most units have an indicator light that shows when they've taken a hit and are no longer providing protection. A single small surge usually doesn't use it up, but a major event can, so it's worth having it checked after any big storm rather than assuming it's still working.
