What to know
- Power surges cause over $1 billion in equipment losses every year across U.S. homes and businesses.
- A whole-house surge arrester at the panel intercepts surges before they reach your electronics.
- Surge protection also reduces fire risk from catastrophic surge events and failing devices.
- Modern homes are full of surge-sensitive equipment: heat pumps, EV chargers, induction ranges, computers, and smart devices.
- Plug strips alone protect one outlet; layered protection starts at the panel.
Where surges come from
Lightning is the dramatic cause, but most surges are smaller and constant: utility grid switching, Puget Sound windstorm outages and restorations, and large motors in your own home (HVAC compressors, well pumps, dryers) cycling on and off. These repeated small surges silently degrade electronics until they fail early.
How a whole-house surge arrester works
Installed at your electrical panel, a surge protective device (SPD) monitors incoming voltage and diverts excess energy safely to ground before it travels through your branch circuits. Everything downstream — the heat pump, the refrigerator, the TV, the garage-door opener, every LED fixture — gets a first layer of protection.
Layered protection is the standard
Best practice pairs a Type 2 SPD at the panel with quality point-of-use protectors on sensitive electronics. The panel device absorbs the big hits; the plug-in units clean up what's left. Current electrical code requires surge protection on new and replaced residential services — a sign of how essential this has become.
Protect the systems you just invested in
If you've added a heat pump, EV charger, generator, or new panel, a surge arrester is cheap insurance on five figures of equipment. Eco installs SPDs during panel upgrades or as a standalone visit, sized and wired per the manufacturer's specifications.

Common questions
Do power strips already protect my house?
Plug-in strips only protect what's plugged into them, degrade with every surge they absorb, and do nothing for hardwired equipment like your HVAC, water heater, or lighting. A panel-mounted arrester protects the whole home at the source.
Will a surge arrester protect against lightning?
It dramatically reduces damage from nearby strikes and utility surges. A direct strike is beyond any device's rating, which is why layered protection and proper grounding & bonding matter — the system diverts as much energy as possible safely to earth.
How long does installation take?
Usually under two hours for a quality Type 2 device on a panel with available space. We verify your grounding system at the same time, because a surge arrester is only as good as the ground path it diverts to.
