Lightning and power surges destroy electronics, HVAC compressors, and appliances. A whole-house surge protector at the panel stops it before it reaches anything inside.
Cliff checks your existing panel for available breaker slots, bus capacity, and condition. The surge protector needs a dedicated two-pole breaker — if the panel is full, we figure out the best option before anything gets installed.
Surge protection only works if your grounding system is solid. We verify the ground rod, bonding connections, and electrode conductor. If anything is missing or corroded — common in older Wilmington homes — we fix it first.
A Type 2 Surge Protective Device gets mounted at the main panel on its own dedicated breaker. Short lead lengths, tight connections, proper torque specs. The device clamps voltage spikes before they reach your branch circuits.
We verify the LED indicator is green, show you where the unit is and what to check after storms, and talk through point-of-use protection for your computers, TVs, and home theater gear.
Most people think surge damage only comes from lightning. Lightning gets the headlines, but the majority of damaging surges come from sources you don't see.
Southeastern NC has some of the highest lightning density on the East Coast. A strike within a mile of your home sends surges through power lines, cable lines, and phone lines. The Wilmington area sees significant thunderstorm activity from May through October.
When Duke Energy restores power after an outage, the initial voltage spike can be well above normal. Transformer switching, grid load balancing, and line maintenance all produce surges that come right through the meter and into your panel.
Your own HVAC compressor, well pump, and large appliances create small surges every time they cycle on and off. Individually they're small. Over months and years, they degrade sensitive electronics — smart TVs, computers, control boards on appliances.
A single surge event can kill a TV, router, garage door opener, or the control board on your refrigerator or washer. Replacing a $40 control board turns into a $400 service call. A whole-house SPD costs less than one fried appliance.
HVAC compressors are the most expensive casualty of surge damage. A new compressor runs $1,500–$3,000 installed. Surges damage the capacitor and windings — sometimes the unit runs for a while before it finally fails, so you don't connect it to the original surge event.
Some homeowner's policies cover surge damage from lightning or utility events, but filing a claim is easier when you can show you had protection installed. A few carriers even offer a discount for having a whole-house SPD. Check with yours.
Surge protection is categorized by where it sits in the electrical system. Each type handles a different job.
A power strip with surge protection is better than nothing, but it has real limitations.
We install whole-house surge protectors across the Wilmington area. Southeastern North Carolina sees heavy thunderstorm activity from late spring through fall, and homes along the coast take the worst of it. Properties in Wrightsville Beach and Figure Eight Island are exposed to coastal storms that bring lightning and utility surges from downed lines and transformer damage. Salt air accelerates corrosion on grounding connections, which makes surge protection less effective if the ground system isn't maintained.
In Hampstead and Leland, new construction homes often come without whole-house surge protection — even though it's one of the cheapest things you can add during or after a build. We also serve Carolina Beach, Kure Beach, Monkey Junction, Myrtle Grove, and Ogden / Porters Neck. If you're adding a surge protector alongside a panel upgrade, generator transfer switch, or EV charger install, we handle it all in one trip.
