Protect your home's appliances, electronics, and HVAC system from destructive power surges with professional whole-home surge protector installation. One of the smartest, most affordable electrical upgrades you can make.
Whole-Home Surge Protection in Murfreesboro
A single power surge can instantly destroy thousands of dollars of electronics, appliances, and HVAC equipment. In Tennessee, lightning strikes and utility grid fluctuations are among the most common — and most destructive — sources of electrical damage. A whole-home surge protection device (SPD) installed at your electrical panel provides the first and most critical line of defense for every circuit in your home.
Murfreesboro Pro Electric installs panel-level surge protectors that meet or exceed the UL 1449 standard and comply with the 2020 NEC requirement for surge protection on new residential installations. Whether you're in a new home or an older property that was never protected, we can add whole-home surge protection in under an hour.
What Can Cause Power Surges?
- Lightning strikes — Extremely common during Tennessee spring and summer storms. Even a nearby strike can induce a massive voltage surge through your utility lines.
- Utility grid switching — Power companies frequently switch loads on the grid, causing voltage spikes that travel directly into your home.
- Large appliance cycling — Air conditioners, refrigerators, and washers create internal surges every time their motors start and stop.
- Outage restoration — When utility power returns after an outage, it often surges briefly before stabilizing. This is a very common cause of appliance damage.
- Downed power lines — Fallen utility lines can deliver uncontrolled voltage directly to your home's service entrance.
- Faulty home wiring — Damaged or deteriorated wiring can create internal surges that cycle through your own circuits.
What Does Whole-Home Surge Protection Cover?
- HVAC systems — one of the most expensive items in your home to replace; extremely vulnerable to surge damage
- Refrigerators, washers, dryers, and dishwashers
- TVs, computers, gaming consoles, and home theater systems
- Smart home hubs, routers, and security systems
- EV charging equipment and associated circuits
- Medical equipment (CPAP machines, nebulizers)
- All wired circuits throughout the home — simultaneously
Panel-Level vs. Point-of-Use Surge Protectors
Panel-level whole-home protectors (SPDs) are hardwired directly into your electrical panel and divert surge energy to ground before it can reach any circuit in your home. This is the most comprehensive and effective surge protection available. A single device protects every outlet, every appliance, and every circuit simultaneously.
Point-of-use protectors (power strips with surge protection) provide an additional layer of protection for individual high-value devices — TVs, computers, gaming systems. They can handle smaller surges and residual energy that passes through the panel-level device.
We recommend a two-layer approach — panel-level protection handles the big surges, point-of-use strips handle residual energy. This is especially important in Murfreesboro where lightning activity is significant during storm season.
The 2020 NEC Surge Protection Requirement
The 2020 National Electrical Code (NEC) now requires surge protection devices on all new dwelling unit service entrances — and many Tennessee jurisdictions have adopted this requirement. If your home was built or rewired recently, it may already include a whole-home SPD. Older homes almost certainly do not. We can inspect your panel and install a listed SPD device quickly and affordably.

Surge Protection FAQ
Does a surge protector wear out?
Yes. Surge protection devices (SPDs) absorb energy during surges, and their protection capacity diminishes over time — especially after large events like lightning strikes. Most quality whole-home SPDs include a diagnostic LED that indicates whether the device is still providing protection. We recommend replacing the SPD if it has taken a significant surge or after 5–10 years of service.
Can I install a whole-home surge protector on any panel?
In most cases, yes. Whole-home surge protectors can be installed on most residential breaker panels, including Square D, Leviton, Siemens, Eaton, and Murray brands. Some older Federal Pacific panels (which we strongly recommend replacing) may require a panel upgrade before an SPD can be properly installed.
Will surge protection prevent my breakers from tripping?
Surge protectors and circuit breakers protect against different things. Breakers protect against overcurrent (too much amperage). Surge protectors protect against overvoltage (too many volts in a spike). Both are needed — surge protectors do not prevent breakers from tripping, nor do breakers stop voltage surges.
Is surge protection worth it in Murfreesboro?
Absolutely. Middle Tennessee experiences frequent thunderstorms, and Murfreesboro is served by both Murfreesboro Electric Department and Middle Tennessee Electric — both of which experience the normal grid switching events that cause surges. A single surge event can destroy your HVAC, appliances, and electronics all at once — far outweighing the one-time investment in protection.
