Whole Home Surge Protection in Eagle, Idaho

Every year, thousands of Treasure Valley homeowners lose televisions, appliances, HVAC systems, and computers to electrical surges — and most of those losses were preventable. A whole-home surge protector installed at your main panel intercepts voltage spikes before they reach your wiring, protecting every device in your home simultaneously. State Street Electric installs whole-home surge protection throughout Eagle, Star, Meridian, Boise, and Nampa, Idaho.

What Whole-Home Surge Protection Does

Point-of-use surge protectors — the power strips you plug into outlets — protect only the devices connected to them, and they have limited joule capacity. A panel-mounted whole-home Surge Protective Device (SPD) intercepts large voltage transients at the source before they enter your circuit wiring. This protects every outlet, appliance, and hard-wired device in your home at once, including your HVAC system, smart home devices, and EV charger — none of which are protected by a power strip.

What Causes Power Surges in the Treasure Valley

• Lightning — Even indirect strikes nearby can send destructive voltage through utility lines into your home. Idaho’s summer storm season makes this a real annual risk.
• Idaho Power utility switching events — Normal grid operations can create momentary overvoltage conditions on distribution lines.
• Large appliance cycling — Air conditioners, heat pumps, refrigerators, and HVAC equipment generate internal surges every time their motors start and stop. These internal surges account for the majority of cumulative appliance damage.
• Downed lines from storms or accidents — Can create severe one-time overvoltage events.

What We Install

We install Type 1 and Type 2 whole-home SPDs from Siemens, Square D, and Eaton — the same manufacturers used by utilities and commercial facilities. A Type 2 SPD installed at the main panel covers the entire home. For maximum protection, we often pair a Type 2 SPD at the panel with a separate SPD at the sub-panel or critical circuit breaker for sensitive electronics. Installation takes less than an hour and requires no changes to existing wiring.

FAQs — Whole Home Surge Protection in Eagle, Idaho

Is a whole-home surge protector the same as a power strip surge protector?
No. Power strip surge protectors have limited capacity and protect only devices plugged into them. A whole-home SPD is a hard-wired device at your main panel that protects every circuit in your home simultaneously, including hard-wired appliances that cannot use a power strip at all.

Will a whole-home surge protector protect my HVAC and EV charger?
Yes. Both are hard-wired devices that cannot use a power strip. A panel-mounted SPD is the only way to protect them from voltage transients. This is one of the most compelling reasons to install whole-home protection before or alongside an EV charger or new HVAC system.

How long does installation take?
Less than one hour in most cases. We mount the SPD at the main panel, connect to a dedicated breaker, and test. No changes to existing wiring.
