Power surges can happen without warning, and the damage they cause can be expensive. Whether it’s a lightning strike, utility fluctuation, or an overloaded appliance inside your home, an unexpected spike in voltage can ruin sensitive electronics. 

It can also and reduce the lifespan of your HVAC system, refrigerator, computer, or even your washer and dryer.

Dunco Heating, Cooling & Plumbing installs whole home surge protection for homeowners in Lawrence, Topeka, and Baldwin. We help protect your electrical system and everything connected to it with devices that absorb excess voltage before it can do harm.

What Is a Home Surge Protector

A home surge protector is a hardwired device installed at your main electrical panel. It deflects or absorbs dangerous spikes in voltage before they reach the outlets, preventing them from damaging appliances and electronics. These protectors:

• Are installed directly to your service panel
• Provide coverage for the entire home’s wiring
• Help shield expensive electronics from internal and external surges
• Can work in combination with point-of-use surge strips for added protection

They’re especially useful in areas with frequent storms, aging power infrastructure, or homes with high-tech or high-efficiency equipment.

Do I Need One?

Not every power surge is noticeable. Many small spikes go undetected but still cause long-term wear on sensitive devices. You might benefit from a whole house surge protector if:

• Your home has experienced lightning-related power outages or surges
• You’ve had to replace appliances sooner than expected
• You own high-end electronics, HVAC systems, or smart home technology
• You’ve noticed flickering lights or unusual appliance behavior during storms
• Your neighborhood has overhead lines or an older electrical grid

Even newer homes are vulnerable, especially as more devices draw power from a single system. Whole home surge protection helps guard against both dramatic events and slow, cumulative damage.

Benefits of a Surge Protector

Installing a home surge protector helps preserve the integrity of your electrical system and adds long-term value by reducing wear and preventing loss. Key benefits include:

• Protection for every outlet and connected device
• Reduced risk of damage during electrical storms
• Increased lifespan of major appliances and electronics
• Fewer service calls related to fried wiring or malfunctioning equipment
• Peace of mind when away from home during a storm or outage

It’s one of the simplest upgrades with the potential to save thousands in replacement costs.

How They’re Installed

Whole home surge protectors are typically installed at your electrical panel. A technician will assess your system, choose a compatible device, and wire it in to intercept voltage spikes before they travel through your home.

At Dunco Heating, Cooling & Plumbing, our team is highly trained in electrical system safety, surge device installation, and panel compatibility. Installation doesn’t take long, and once in place, the surge protector works automatically to detect and deflect damaging power spikes.

We also evaluate your home’s power usage and panel capacity to ensure the system can handle current and future electrical demands.

FAQs

What causes a power surge?

Power surges can come from lightning strikes, utility grid switching, downed lines, or even large appliances cycling on and off inside your home.

Will a surge protector stop lightning damage?

While no device can offer complete protection from a direct lightning strike, a whole house surge protector can help redirect or absorb voltage from nearby strikes and grid disturbances.

Do I still need plug-in surge strips?

A whole home surge protector covers your entire system but pairing it with quality surge strips at key outlets adds an extra layer of protection for sensitive electronics.

How long does a whole home surge protector last?

Most devices last between 5 to 10 years, depending on the number and intensity of surges they absorb. Regular electrical inspections help ensure your system remains protected.

Can I install one myself?

No. These devices connect directly to your electrical panel and must be installed by a qualified technician.
