A Type 2 panel-mounted surge protector clamps voltage spikes from lightning, transformer faults, and utility switching before they reach your HVAC, EV charger, appliances, and electronics. Installed in 1–2 hours. Owns the spike protection long-term — no monthly rental.
South Carolina averages 50+ thunderstorm days per year — among the highest in the country. Most lightning damage to homes isn't from direct strikes; it's from induced surges when lightning hits nearby and pulses through the grid, plus transformer failures and utility switching events. A point-of-use strip surge protector at one outlet does nothing for your HVAC condenser, EV charger, range, or hardwired security system.
A whole-home Type 2 SPD installs at your breaker panel and clamps spikes across every circuit in the house at once. Quality units (Square D, Eaton, Siemens, Leviton) are rated for tens of thousands of strikes over their lifetime and self-indicate when they reach end-of-life.
Versus Dominion's rental: Dominion Energy's Smart Hub surge program runs about $9.99/month — that's $120/year, ongoing. A permanent whole-home install is typically $450–$900 once, and the device lasts 10–15+ years. Most Columbia homeowners break even in under 2 years and end up with stronger protection that they own.
Installed inside (or directly beside) your breaker panel. The standard whole-home install for residential Columbia homes — protects every circuit at once.
Installs between the utility meter and your panel — first-stage defense against direct lightning. Paired with a Type 2 for the most aggressive setup.
Dedicated SPDs at the HVAC condenser, EV charger, AV stack, and home-office gear. Layered protection for the highest-value loads.
Generac and Kohler standby installs don't include whole-home surge by default. We pair the two so your home is protected when power is on and when the generator kicks in.
Already have a whole-home SPD installed? Bring us your panel and we'll tell you if the LED indicator is still green or if you've used the device up.
Took a hit? We'll inspect the SPD, replace it if it's spent, and check downstream devices for damage. Common after big Midlands storms.
We install whole-home surge protection across all of Columbia and the Midlands — especially valuable for storm-exposed Lake Murray, Blythewood lightning country, and rural Elgin.
Dominion's Smart Hub rental is roughly $9.99/month and includes only meter-side protection plus a small per-claim equipment-replacement warranty. A permanent panel-mounted Type 2 surge protector is a one-time install ($450–$900 typical), uses a higher-joule device that survives more strikes, and continues protecting your home indefinitely. Most Columbia homeowners break even on the install vs. the rental in under 2 years and own equipment that lasts 10–15+ years.
A quality Type 2 surge protector (Square D, Eaton, Siemens, Leviton) lasts 10–15+ years under typical Columbia conditions. Most models have an LED indicator that turns off when the device has absorbed too many strikes and needs replacement. We swap units in 30 minutes if yours has reached end-of-life — bring the LED panel and we'll tell you on the spot.
Yes — surge protection and a generator do different things. The generator keeps the lights on when grid power is out. The surge protector clamps voltage spikes from lightning, transformer faults, and utility switching events that happen while power is on. Generac units do not include a whole-home SPD by default. We typically install both together for storm-exposed Lake Murray and Lexington homes.
Type 1 SPDs install on the service-entry side (between the utility meter and your panel) and are designed for direct lightning protection. Type 2 SPDs install inside the panel and protect against indirect surges plus grid-side spikes — these are the standard whole-home install for residential Columbia homes. The most aggressive setup combines both: a Type 1 at the meter and a Type 2 at the panel for layered protection.
No SPD stops a direct strike to your home — a direct hit delivers more energy than any consumer-grade device can clamp. What a Type 2 SPD does stop is the much more common problem: induced surges from nearby strikes, transformer failures, and utility switching. South Carolina averages 50+ thunderstorm days per year, and the vast majority of damage comes from these induced surges, not direct hits. Adding a Type 1 SPD at the meter improves direct-strike protection significantly.
Typical install is $450–$900 for the Type 2 panel-mounted device plus labor and permit. Adding point-of-use SPDs (HVAC condenser, EV charger, AV stack) adds $75–$150 per location. A Type 1 service-entry SPD adds $300–$500. We quote per home after looking at your panel — older panels sometimes need a small breaker rework to make room for the SPD.
One install. One bill. 10+ years of protection.
