If you’ve ever experienced flickering lights during a thunderstorm or had an expensive appliance die for no apparent reason, chances are you’ve been affected by a power surge. But what many homeowners don’t realize is that these surges are more common—and more damaging—than you might think. That’s where whole house surge protection comes in.
At Bowen Electric, we specialize in helping homeowners across Waco, TX, protect their homes and electronics from sudden, unexpected power spikes. In this post, we’ll break down exactly what whole house surge protection is, how it works, and why it’s one of the smartest investments you can make for your home.
What Is Whole House Surge Protection?
Whole house surge protection is an electrical safeguard that shields your home’s entire electrical system from power surges. Unlike power strip surge protectors that only protect a single outlet or device, whole house systems are installed directly at your electrical panel, intercepting and neutralizing dangerous voltage spikes before they can travel through your wiring and damage your appliances or electronics. These systems are designed to:
- Divert excess voltage away from your home’s electrical circuits
- Protect every outlet, device, and appliance connected to your home’s wiring
- Work 24/7, whether the surge comes from outside (like lightning) or inside (like a cycling HVAC system)
What Causes Power Surges?
Most people associate surges with lightning, and while lightning is definitely a major threat, it’s far from the only source. In fact, up to 80% of power surges come from inside the home. Here are the most common causes of electrical surges:
1. Lightning Strikes: A nearby lightning strike can send a massive spike of electricity into the power lines connected to your home.
2. Utility Grid Issues: Power outages, downed lines, or routine maintenance by your utility company can cause voltage fluctuations.
3. Large Appliances Switching On/Off: Every time your HVAC system, refrigerator, or dryer kicks on or off, it causes a minor surge. Over time, these add up and wear down your electronics.
4. Faulty Wiring or Panels: Outdated or poorly installed wiring can cause irregular voltage and increase your risk of surges.
Even if you never notice them, small daily surges can slowly degrade electronics, shortening their lifespan and increasing the risk of failure.
What Can Be Damaged by a Power Surge?
Nearly everything you plug in can be affected by a surge. Here’s a short list of high-risk items:
- Smart TVs and home theater systems
- Refrigerators and dishwashers
- Washers and dryers
- Computers, laptops, and modems
- Smart thermostats and home automation systems
- Electric vehicle (EV) chargers
- LED lighting and fixtures
- Medical equipment
A single surge could cost you thousands in replacements—or worse, trigger an electrical fire.
How Does Whole House Surge Protection Work?
Whole house surge protectors are typically installed at your main electrical panel. When a surge occurs, the device detects the excess voltage and safely redirects it to ground, preventing it from traveling through your home's wiring and reaching your plugged-in devices. Most systems utilize metal oxide varistors (MOVs)—components that absorb or block high voltages and dissipate them safely. Some advanced units also feature thermal protection and visual indicators to indicate when the device is still functioning properly.
Do You Really Need Whole House Surge Protection?
The short answer? Yes—especially in areas like Central Texas, where electrical storms are common and energy demand is high. Here’s why we recommend it to nearly every Waco homeowner:
- Protects every circuit, not just a few outlets
- Prevents costly appliance damage
- Reduces fire risk
- Extends the life of your electronics
- Peace of mind—your home is protected 24/7
You wouldn’t drive your car without insurance. Why run your home without protection from unpredictable power surges?

Frequently Asked Questions
Q: How long does a whole house surge protector last?
A: Most units last between 5 and 10 years. They may need to be replaced after a major surge event. We recommend periodic checks as part of your home’s electrical maintenance.
Q: Can it protect against direct lightning strikes?
A: Whole house surge protectors can help reduce damage from nearby lightning strikes, but direct hits may still cause severe damage. For full lightning protection, a comprehensive system, including lightning rods, is needed.
Q: Do I need one if I already use surge protector strips?
A: Yes. Strips only protect individual devices. Whole-house surge protection defends your entire electrical system at its source.
Q: Does it work during power outages?
A: Yes—surge protectors defend against the return of power after an outage, which is when surges often occur.
Q: Will it affect my home’s electricity or usage?
A: Not at all. Surge protectors operate silently in the background and don’t impact your electricity use or bills.
