A lightning strike near your home can cause hidden electrical damage even if nothing seems wrong. Here’s what to check \u2014 and why you shouldn’t wait.<\/em><\/p>\n

\n

When lightning strikes nearby, the damage isn’t always obvious. No fire. No tripped breakers. No obvious signs anything went wrong. But beneath the surface, a strike can quietly destroy electronics, compromise wiring, and set the stage for problems that show up weeks later \u2014 sometimes in dangerous ways.<\/p>\n

If you’ve had a lightning event near your Middle Tennessee or North Alabama home, here’s what actually needs to be inspected before you assume everything is fine.<\/p>\n

\n

Why “Nothing Looks Wrong” Isn’t Good Enough<\/strong><\/p>\n

Lightning doesn’t have to hit your home directly to cause damage. A nearby strike \u2014 even one that hits a utility pole down the road \u2014 can send a powerful voltage surge traveling through your electrical system in a fraction of a second. That surge can degrade components, destroy sensitive electronics, and stress your panel and wiring in ways that aren’t immediately visible.<\/p>\n

The problem is that some of this damage doesn’t announce itself. An appliance may seem to work fine for days before it fails. A wiring connection that was weakened by the event may hold up just long enough for you to stop worrying about it.<\/p>\n

\n

Start at the Panel<\/strong><\/p>\n

Your electrical panel is the first place to check. Open it up and look for any breakers that have tripped. Reset them and monitor whether they trip again under normal load. A breaker that keeps tripping after a lightning event isn’t just an annoyance \u2014 it’s a signal that something in the circuit has been compromised.<\/p>\n

Also look for any signs of scorching, melting, or an unusual burning smell inside the panel. If you notice any of these, don’t attempt to reset breakers or operate the panel further \u2014 call a licensed electrician immediately.<\/p>\n

What homeowners often miss: surge damage to the panel can degrade breakers in ways that aren’t visible at all. A breaker can look perfectly normal and still fail to trip when it should, which removes your home’s primary protection against electrical faults.<\/p>\n

\n

Check Your Whole-Home Surge Protector<\/strong><\/p>\n

If you have a whole-home surge protector installed at your panel, check it after any significant lightning event. Most quality units have an indicator light or window that shows whether the device is still functional. Surge protectors work by absorbing excess voltage \u2014 which means they can sacrifice themselves to protect your system. After a large strike, they may need to be replaced even if everything else appears normal.<\/p>\n

If you don’t have a whole-home surge protector, a lightning event is the perfect time to seriously consider one.<\/p>\n

\n

Go Through the House Room by Room<\/strong><\/p>\n

Walk through every room and test outlets, switches, and fixtures. Pay attention to:<\/p>\n

    \n
  • Outlets or switches that no longer work<\/li>\n
  • Outlets that feel warm to the touch<\/li>\n
  • Lights that flicker when they didn’t before<\/li>\n
  • Any unusual burning smell from outlets or switch plates<\/li>\n<\/ul>\n

    Don’t skip rooms you don’t use regularly. Surge damage doesn’t limit itself to the areas of your home you check most often.<\/p>\n

    \n

    Electronics and Appliances: More Than Just “Does It Turn On?”<\/strong><\/p>\n

    Just because something powers on doesn’t mean it survived unscathed. Surge damage to electronics is often partial \u2014 the device works, but certain functions are degraded or a component inside is running hot and on borrowed time.<\/p>\n

    Check these specifically:<\/p>\n

    HVAC system.<\/strong> Your air conditioner or heat pump has control boards and capacitors that are particularly vulnerable to surges. If your system seems to be running but short-cycling, struggling to reach temperature, or making new noises, it may have sustained damage that isn’t obvious from the outside.<\/p>\n

    Refrigerator and freezer.<\/strong> These run continuously and draw significant power, making them common casualties. Check that compressors are running normally and that temperatures are holding steady.<\/p>\n

    Televisions and entertainment equipment.<\/strong> These are notoriously sensitive. Power them on fully and run them through their paces \u2014 not just the basic power-on test.<\/p>\n

    Wi-Fi routers, modems, and smart home hubs.<\/strong> Many homeowners don’t realize their internet is running on a damaged router until performance degrades significantly. A quick factory reset can sometimes reveal whether the device is functioning correctly.<\/p>\n

    Well pumps.<\/strong> If you’re on a private well, check your water pressure and listen for any change in how the pump sounds when it cycles on. Well pump control boxes contain capacitors that are frequently damaged by power surges, and a compromised pump is expensive to ignore.<\/p>\n

    \n

    Don’t Overlook Outdoor Equipment<\/strong><\/p>\n

    Surge energy can travel through more than just your electrical panel. If your home has any of the following, inspect them carefully:<\/p>\n

      \n
    • Landscape lighting and irrigation system controllers<\/strong> \u2014 often connected to low-voltage systems that are easily damaged<\/li>\n
    • Detached garage or shop wiring<\/strong> \u2014 especially if on a subpanel<\/li>\n
    • Security cameras and exterior lighting<\/strong> \u2014 frequently connected and powered continuously<\/li>\n
    • Pool or hot tub equipment<\/strong> \u2014 motors and control boards in these systems are expensive to replace and vulnerable to surges<\/li>\n<\/ul>\n
      \n

      What Only a Professional Inspection Can Find<\/strong><\/p>\n

      Some lightning damage simply cannot be identified without professional equipment. Thermal imaging cameras can reveal hot spots in wiring or behind panels that don’t show up during a visual inspection. A licensed electrician can also test wiring integrity, verify that your grounding system is functioning correctly, and identify degraded components before they become failures \u2014 or hazards.<\/p>\n

      This is especially important in older homes, where wiring connections can be more vulnerable, and in homes where any previous DIY electrical work may have created weak points in the system.<\/p>\n

      \n

      When to Call Right Away<\/strong><\/p>\n

      Don’t wait for a scheduled inspection if you notice any of the following after a lightning event:<\/p>\n

        \n
      • A burning smell anywhere in the home<\/li>\n
      • Outlets or switches that are discolored, warm, or sparking<\/li>\n
      • Breakers that trip repeatedly<\/li>\n
      • Any signs of visible scorching or melting at outlets or the panel<\/li>\n
      • Loss of power to portions of the home with no clear cause<\/li>\n<\/ul>\n

        These are situations where the risk of electrical fire is real and waiting makes it worse.<\/p>\n

        \n

        After the Storm Passes<\/strong><\/p>\n

        Lightning season in Middle Tennessee and North Alabama isn’t a short window \u2014 it runs through spring, summer, and well into fall. If your home has been through a significant storm, a professional inspection isn’t an overreaction. It’s the fastest way to know whether your family is safe and your equipment is protected.<\/p>\n
