Why Surge Protection Is More Critical Than Ever

In today’s connected homes, sensitive electronics are everywhere — smart TVs, appliances, HVAC systems, and home automation hubs. One power surge can instantly damage or destroy these devices. With Iowa’s severe thunderstorms, lightning activity, and utility grid fluctuations, surge protection isn’t a luxury — it’s essential.

What Is a Power Surge?

A power surge is a sudden and brief spike in voltage traveling through your home’s electrical system. Most homes operate on 120 volts. A surge can push that well beyond safe levels — damaging anything plugged into the system.

Common Causes of Surges:

Lightning strikes nearby
Downed power lines
Restoration after an outage
High-powered appliances cycling on/off (HVAC units, refrigerators)

These events can send thousands of extra volts through your wiring in an instant.

Why Plug-in Surge Protectors Aren’t Enough

While power strip surge protectors are common, they only protect individual outlets — and many offer minimal protection. They don’t shield hardwired systems like HVAC units, ovens, washers, or smart panels. Worse, many homeowners assume they’re protected when they’re not.

Limitations of Plug-In Units:

Can’t handle large voltage spikes
Don’t protect entire circuits
Have a limited lifespan — and many lack indicators when they fail

That’s where whole-home surge protection comes in.

Benefits of Whole-Home Surge Protection

A whole-home surge protector is installed directly into your main electrical panel. It shields your entire home’s wiring from surges, stopping the threat before it reaches your outlets or devices.

Key Advantages:

Protects all devices — not just what’s plugged into a strip
Defends major systems — HVAC, refrigerator, washer/dryer, smart thermostats
Reduces risk of electrical fires caused by overloaded circuits
Saves money by extending the life of electronics and appliances

With many Iowa homes now using smart home devices and connected systems, whole-home surge protection has become a critical safety upgrade.

Cost of Installation in Iowa

Whole-home surge protectors are surprisingly affordable. Installation typically ranges from $300 to $800, depending on your panel type and protection level. It’s a one-time investment that could save thousands in replacement costs.

At Coffin Electric, we recommend surge protection during panel upgrades, smart home installs, or generator setups — when your system is already being accessed.

When Should You Install Surge Protection?

Timing is key. Don’t wait until a damaging surge strikes. Consider installing or upgrading surge protection if:

Your home has smart devices or appliances
You’ve recently upgraded your panel
You’re installing a generator or EV charger
You’ve experienced frequent power outages or flickering lights

Spring and summer — Iowa’s peak storm seasons — are ideal times to prepare.

Surge Protection FAQs

Q: Does My Insurance Cover Surge Damage?

A: Many policies don’t fully cover electronic or appliance damage from surges. Preventive protection is far more reliable.

Q: Will It Stop All Surges, Including Lightning?

A: Whole-home protectors can block most surges, but a direct lightning strike may still cause damage. Additional point-of-use protection is recommended.

Q: How Long Does a Surge Protector Last?

A: Most have a lifespan of 5–10 years. Some include indicator lights to show when replacement is needed.
