Power surges happen more often than you think—and they don't just come from lightning strikes. Everyday events like utility grid fluctuations, downed power lines, or even large appliances cycling on and off can send damaging voltage spikes through your home. For sudden electrical issues, our emergency repair service responds fast.
These surges can shorten the lifespan of your electronics, damage expensive appliances, and even cause fires. A whole-house surge protector is the most effective way to safeguard everything connected to your electrical system. Josh LaFerriere Electric provides expert installation for complete peace of mind.
What Is Whole-House Surge Protection?
A whole-house surge protector is installed directly at your main electrical panel. It acts as a gatekeeper, filtering excess voltage before it reaches any device or appliance in your home.
Unlike power strips that protect individual outlets, a whole-house system protects every circuit in your home simultaneously—including hardwired appliances like your HVAC system, water heater, EV charger, and electric range that can't be plugged into a strip.

Benefits of Whole-House Surge Protection
Single Solution for Your Entire Home
Instead of relying on individual power strips at every outlet, one device at your panel protects every circuit and every device in your home—including hardwired appliances.
Works 24/7 Automatically
Once installed, your surge protector works silently around the clock. No batteries, no maintenance, no buttons to press. It's always protecting your home.
Affordable One-Time Investment
Compared to the cost of replacing damaged electronics and appliances, a whole-house surge protector is a smart, affordable investment that pays for itself.
Common Sources of Power Surges
- Utility Grid Fluctuations: Switching events and load changes on the power grid cause frequent small surges that add up over time.
- Lightning Strikes: A nearby lightning strike can send massive voltage spikes through power lines and into your home.
- Large Appliance Cycling: Your HVAC system, refrigerator, hot tub, and other large appliances create small surges every time they cycle on and off.
- Downed Power Lines: Storms and accidents can cause downed lines that send irregular voltage into the grid.
- Utility Restoration: When power is restored after an outage, the initial surge can damage unprotected devices. A generator with a transfer switch helps manage power transitions safely.

What our customers say
Lucas Bernacki
August 2026
Josh (and Charlie) provided excellent service. We called for a site visit and an estimate. They got us on the schedule within a week, showed up on time, offered a fair price, and were able to complete the work the same day! After they replaced the electrical panel, they took the time to work with me to test and clearly label each switch.

Josh was professional through and through. He responded quickly, came out to assess my new circuit installation needs and discussed options, clearly listening to my concerns. He then gave me an upfront estimate and got it all done same day. The new run is tidy, he cleaned up thoroughly, and was overall great to work with.

Josh has done two projects for us, including troubleshooting some non-working outlets and installing a new bathroom fan. He’s extremely courteous, professional, reliable, and offers fair pricing. Highly recommend for any electrical needs!
Whole House Surge Protection FAQs
How is this different from a power strip?
A whole-house unit sits at the panel and protects the entire service. Strips only cover what is plugged into them.
Should I add one when I upgrade the panel?
Yes. Panel-open is the cleanest time to install a Type 2 surge device.
Does it protect against a direct lightning strike?
No device can promise that. A whole-house unit is still the right first layer for utility surges and nearby strikes.
How long does installation take?
Most installations are completed in a single visit at an existing panel.
Do I still need point-of-use strips?
They are a useful second layer for TVs and computers. The panel device is the whole-home layer.
