Lightning and Power Surges in Broward

Thunderstorm season on the Broward calendar

From late spring into early fall, warm humid air over South Florida builds towering storm clouds almost every afternoon. Many Broward residents plan their errands around the daily rain, and many have had a storm interrupt dinner with a flash, a crack and a brief flicker of every light in the house.

Those moments are more than a nuisance. A nearby strike can push a spike of energy along power lines, phone and cable lines, pool wiring and even the ground, and that spike goes looking for a path through your home. Air conditioners, televisions, routers and appliance control boards are common victims.

We cannot prevent lightning, and no device can promise that a home will never be damaged. What we can do is reduce the chances and limit the harm by checking how your electrical system is built, strengthening the weak points, and adding layers of protection that suit the way you live.

It helps to know what a storm looked like from the inside of the house. Did the lights flicker once, or did power drop and return several times? Did a single room lose power, or the whole house? Did the air conditioner restart on its own or stay off? Those details tell an electrician a lot about where the energy went and which parts of the system were stressed. If you keep a short note on your phone after each major storm, you will build a useful history that makes any later troubleshooting faster and far more accurate, especially if the same symptoms keep returning. Because storms here are so predictable, a small amount of seasonal preparation goes a long way, and the quiet weeks before summer are a good time to have the system checked.

Direct strikes and the surges that arrive without one

People tend to picture lightning hitting the roof. That does happen, but most damage comes from strikes that land somewhere nearby. A strike on a utility pole, a tree, a transformer or the ground can send a surge along wires or through the soil that reaches your house moments later.

Surges also come from ordinary sources. When utility crews switch power, when a large motor on the grid cycles, or when a transformer fails, the voltage can jump briefly. Inside the home, compressors and pumps starting up create small surges of their own, which age electronics slowly.

This is why we talk about surge protection as layers. A strong device at the panel handles the big events, protection at sensitive equipment catches what remains, and good grounding gives the energy a safe place to go. No single piece does everything, and we explain which pieces matter most for your house.

Several things can look like lightning damage and turn out to be something else. A tree limb that rubbed a service line, a failing neighborhood transformer, a loose connection at the meter, or a worn breaker can all cause flickering and failures at the same time as a thunderstorm. This is why we do not assume the storm is the whole story. We check the service entrance, the meter connections and the panel, and when the problem lies with the utility side of the meter, we tell you so and explain how to report it to the utility. Understanding these routes helps explain why homes with good wiring can still lose equipment, and why a careful inspection looks at more than the panel alone.

What a whole-house surge device actually does

A whole-house surge protective device is installed at or near the electric panel. When voltage rises above a safe level, it diverts the excess energy toward the grounding system instead of letting it flow into the circuits. It is not a battery and it does not make the power cleaner on an ordinary day.

Placement and wiring matter. The device needs short, direct connections to the panel and to the grounding path, since long leads weaken its effect. It also needs a dedicated breaker of the right size. Careless installation is one of the main reasons these devices underperform.

These units wear out. They absorb energy each time they work, and many have indicator lights that show whether protection remains. After a major storm, we suggest checking the indicator and replacing the device if it shows a fault. A device that quietly stopped working offers a false sense of security.

Think of protection as an investment in the equipment you would miss most. A television or router can be replaced, but a medical device, a home office computer with irreplaceable files, or an air conditioning control board during a hot week is a bigger loss. We often ask owners to rank what matters to them and build the protection plan around that ranking. It keeps the plan proportionate, avoids buying more than you need, and ensures the places where a failure would hurt most are covered first by the best layer of protection available. Surge protection reduces risk and does not remove it, and a very close strike can overwhelm any device, so we set realistic expectations before we install one for you.

Protecting the equipment that matters most

A panel-mounted device is the first line, but sensitive electronics benefit from a second. Point-of-use surge strips and outlets sit near televisions, computers, home theaters, routers and medical equipment. They catch smaller surges that get through, and those created inside the house.

Quality varies widely. Some strips are little more than extension cords with a switch. A useful protector lists clear ratings and a protection indicator, and it should be replaced after a severe event or when the indicator fails. Using one for a heater or other heavy load defeats its purpose.

Do not forget the other wires entering the home. Cable, satellite, phone and network lines can carry surges just as power lines do. Protection works best when every line passes through the same protected path, and when the equipment is connected to the same ground reference. We look at all of these entry points during a visit.

Installation details separate a device that works from one that merely sits there. Lead length, breaker size, wire gauge, the tightness of each lug and the quality of the grounding connection all influence performance. A surge device mounted on the far side of a crowded garage with long loops of wire is far less effective than one mounted right beside the panel with short, straight leads. We install them for performance, label them clearly, and leave a note of where the indicator can be found so you can check it after storms. If you are unsure where to begin, start with the equipment that would be hardest to replace and work outward from there, one sensible layer at a time.

Grounding and bonding: the unseen foundation

Surge devices rely on the grounding system to carry energy away. If the ground is poor, corroded or missing, the device has nowhere to send the surge, and the energy may find its own route through your equipment. Grounding is the part owners never see and installers sometimes neglect.

In Florida, soil can be sandy and dry in some places and saturated in others, and salt air attacks metal. Ground rods, clamps and conductors can corrode over time. Older homes may have ground connections that were never up to modern standards, or that were disconnected during renovations.

Bonding connects metal systems together so they rise and fall in voltage as one, reducing the chance of dangerous differences. This includes water piping, gas piping, the cable and phone entries and the panel. We inspect these connections, repair what is loose or corroded, and explain what we find in plain language.

Ask yourself where your cable, satellite, internet and phone lines enter the home, and whether they are connected to the same grounding point as the electrical service. Separate ground rods that are not tied together can allow dangerous differences in voltage during a strike, which is one of the ways equipment is destroyed even when a surge device is present. Bringing everything to a common reference is a basic but often overlooked improvement, and it is something we check on nearly every older property we visit across the county. Ground rods, clamps and bonding jumpers are inexpensive parts, yet they carry real responsibility, and verifying them is among the most valuable half hours spent on any electrical visit.

Lightning protection systems and when they come up

A lightning protection system is different from surge protection. It consists of air terminals, conductors and grounding designed to intercept a direct strike and guide it safely to ground, away from the structure. These systems are specialized work and follow their own standards.

Not every home needs one. Owners with tall structures, isolated buildings, large trees close to the house, or properties with valuable equipment sometimes ask about them. Surge protection and lightning protection work together, since a system that handles the strike still leaves surges on the wires.

We can discuss what such a system involves in general terms and help coordinate with specialists where appropriate. Our focus is making sure the electrical service, grounding and surge protection are sound, since those parts affect how any lightning system would be tied into your home.

If you are curious about lightning protection, a good first conversation covers the structure itself: roof type, height, nearby trees, surrounding open space and any valuable equipment inside. Many homeowners find that a well-grounded electrical service with solid surge protection answers most of their concerns. Others, with unusual properties, benefit from a specialist who designs and installs full protection. We are happy to give our view on how the electrical service would connect to such a system, and we are honest when a project belongs with another trade. When in doubt, a phone call is a good start, and we will tell you honestly whether a specialist system is worth considering for your property. That honesty matters, because a specialist system is a significant project.

Pools, lanais, outdoor lighting and detached structures

Outdoor electrical systems are exposed in ways indoor wiring is not. Pool pumps, heaters, lighting, lanai fans, outdoor kitchens, gate openers, irrigation controllers and detached garages all extend the electrical network into open yards where lightning can reach them.

Long buried or overhead runs to a detached building can act like antennas for surges. Such structures often benefit from their own protection and a proper ground system, connected as required. We look at how power travels from the panel to each outbuilding and whether its protection is adequate.

Pool areas have additional rules about bonding and ground-fault protection, designed to keep people safe in and around water. If a thunderstorm approaches, everyone should leave the pool and stay away from outdoor electrical equipment. After a storm, any odd behavior from pool lights or pumps deserves a professional look before use.

Landscape lighting, gate operators and irrigation controllers are quiet victims. They are connected to long low-voltage runs that pick up surges, and their transformers sit outdoors in humid, salty conditions. A controller that dies after each storm is telling you that protection and grounding are inadequate or that moisture is getting in. We check the supply wiring, the transformer location, the weatherproofing and the grounding, and suggest targeted protection so you are not replacing the same small, inexpensive parts repeatedly while the cause remains unaddressed. Never stand near outdoor electrical equipment or in the water during a thunderstorm, and let any suspicious fixture be checked by a professional before you use it again after the weather passes.

Air conditioners, appliances and the damage you notice later

Air conditioning systems carry sensitive control boards and large motors, and they are frequent casualties of surges. Sometimes a unit stops immediately. Other times a board is weakened and fails weeks later, and the connection to the storm is not obvious.

Refrigerators, washers, dryers, ovens and garage door openers contain control electronics too. A pattern of strange behavior after a storm, such as lights dimming, breakers tripping or devices resetting, is worth investigating. It can point to damaged wiring or loose connections as well as failed equipment.

We often find that homes with repeated losses have a weak point in the electrical system, such as a loose neutral connection or poor grounding. Treating the symptoms by replacing equipment again and again can be frustrating and expensive. Finding the underlying cause is more effective and protects the next appliance you buy.

Not every failure after a storm is a surge. Compressors and motors that run hot in Broward's heat can fail on their own, and a thunderstorm simply happens to coincide with the moment of failure. A careful look separates the two. Measuring voltage at the panel, inspecting connections, checking breakers and reviewing the age of equipment help establish what happened. That evidence matters when you are deciding whether to repair or replace, and it helps avoid spending money on protection for a problem that was never caused by a surge. Keeping a record of purchase dates and storm events also helps decide when repair stops making sense, and it gives any technician a clearer picture of the history.

Older panels and wiring in older Broward homes

Many Hollywood and Broward homes were built decades ago, long before modern electronics. Their panels may have limited grounding, few spare spaces for protection and aging breakers. Older wiring can have brittle insulation and connections that have loosened with years of heat and humidity.

Loose connections matter for surge events, since high energy at a poor connection creates heat and arcing. Corrosion from salt air makes it worse. A thorough inspection includes looking at the panel for discoloration, rust and signs of overheating.

Upgrading a panel can allow modern protection devices to be installed correctly. In some cases the best step is to improve the service, grounding and bonding first, then add surge protection on top. We lay out the sequence so you understand what each step contributes and why the order matters.

Panel age is not the only issue. The brand and type of panel, the condition of its bus bars and the presence of double-tapped or overloaded breakers all influence whether adding protection makes sense right away or whether the panel needs attention first. Some older panel designs have a record of problems that electricians and inspectors watch for. We assess your equipment honestly and describe the options, from targeted repairs to full replacement, along with the tradeoffs in disruption, time and long-term reliability so you can choose with confidence. Being candid about the age and condition of the panel saves money in the long run, because a protection device can only work as well as the equipment it is connected to.

Permits and code requirements for surge protection

Modern electrical codes recognize the value of surge protection in many dwelling situations, and recent editions have required it in certain cases when services are installed or replaced. The specifics depend on the code edition adopted locally and on the work being done.

Because the local building department enforces the adopted code, we confirm what applies to your address and project. Work that involves the panel or service is generally permitted and inspected where the code requires it, and we do not promise approvals.

Even where a device is not mandatory, many owners choose it for peace of mind. We can explain the choices without pressure. A clear, general discussion of what the code requires and what is simply good practice helps you decide where to put your attention and your budget.

Owners sometimes ask whether adding protection will raise concerns with an inspector or insurer. Generally, properly installed surge protection is viewed favorably, and installation through the panel is handled under permit where required. We encourage you to keep records: the device model, installation date, permit information if any, and photos of the installation. If you are ever asked about your electrical system by an insurer or a buyer, an organized file makes the conversation easy, and it demonstrates that the work was done with care and reviewed where the code required. Keep copies of permits and inspection results with your home records, along with the model and date of any device, since future buyers, insurers and electricians will all appreciate having them close at hand.

Condos, townhomes and shared buildings

In a multi-unit building, the main service and some wiring belong to the association, while the panel and wiring inside the unit belong to the owner. That split affects who can install protection where. Common-area equipment, elevators and pumps may be protected at the building level.

Owners can still do a lot inside their unit. A device at the unit panel, point-of-use protection and sensible habits during storms all reduce risk. Check your documents for any rules about work on panels or penetrations, and talk with management before starting.

Beachfront and high-rise properties face their own mix of exposure, with tall structures, salt air and long runs of wiring. We are glad to discuss general approaches with a property manager or board, but decisions for common equipment belong to the association and its advisors.

If your building association has rules about work in common areas or limits on the hours when contractors can work, share those with us in advance. Elevators, hallways, shared meter rooms and rooftops often have access limits. Planning around them avoids delays and misunderstandings. In many buildings, protection for the entire building is an association project, and individual owners are limited to their own units, so a quick conversation with management can clarify what is possible. We can help prepare a clear, written scope that the board can review. Clear communication with management and neighbors keeps projects moving and prevents misunderstandings, and it ensures that work respects the rules every resident has agreed to follow. This keeps everyone informed and the work orderly.

Before you call, and when to call right away

Preparation helps. Write down what happened: which devices failed, when, and what you noticed beforehand. Photograph labels on equipment and the front of the panel. Note any burning smell, scorch marks or breakers that will not reset. That information helps us decide where to look first.

If you see sparks, smell burning, hear buzzing from the panel or notice warm outlets, treat it as urgent. Turn off power only if you can do so safely and call a professional. Stay away from downed lines and wet areas near electrical equipment.

We answer an emergency line, and callers should phone to confirm availability. Jobs are quoted after we understand the work, and some need a visit first. If a service call charge applies, it is explained before dispatch, so you know what to expect before anyone is sent.

Finally, a note about habits. During severe storms, unplug computers, televisions and other valuables if you can do so safely before the weather arrives, and avoid using corded electronics or standing at plumbing fixtures during close lightning. Keep devices off the floor in rooms that may flood. After the storm, if something smells or sounds wrong, do not ignore it. Honest awareness, good equipment and prompt professional attention when something looks off form a practical approach, and it keeps a bad afternoon from becoming a bad month. Surge protection reduces risk and does not remove it, so layers, good grounding and regular checks give the best results. If you want to talk about your home, call and we will walk through it.

Questions we hear about this

Do I need a whole-house surge protector in Broward County?

Many owners choose one because of frequent summer thunderstorms and the amount of electronics in modern homes. Recent code editions require protection in certain situations, depending on the work and local adoption. We confirm what applies to your address and explain the choices without pressure, so you can decide what fits your home.

Will a surge protector stop a direct lightning strike?

No device can promise that. Surge protection reduces the harm from most surges, especially those arriving on wires, but a very close direct strike can overwhelm any protection. Layers of protection, solid grounding and sensible habits such as unplugging valuable electronics during severe storms all help limit damage. We are glad to answer follow-up questions before any work is planned or scheduled.

Why do my appliances keep failing after storms?

Repeated failures can point to an underlying issue, such as poor grounding, loose connections or a weak neutral, as well as to the surges themselves. We inspect the panel and grounding, look at how power enters the home, and recommend repairs and protection that address the cause instead of replacing equipment over and over.

How do I know if my surge device still works?

Many devices have an indicator light or display showing whether protection remains. These units absorb energy each time they work and can wear out, especially after a major storm. If the indicator shows a fault, or if you are unsure, have a professional check it and replace it if needed. Every property is different, so we look at yours before suggesting anything specific.

Does grounding really matter for surge protection?

Yes. A surge device sends excess energy to the grounding system, so a corroded, loose or missing ground limits what it can do. Bonding of piping and communication entries matters as well. We inspect these connections and repair what is worn, since protection is only as good as the path it relies on.

What does a visit cost and what does it involve?

We look at the panel, grounding, bonding and the way lines enter your home, then explain what we find. Jobs are quoted after we understand the work, and some need a visit first. If a service call charge applies, it is explained before dispatch, so there are no surprises about what a visit involves.
