Whole-Home Surge Protection in Southern NH and the Merrimack Valley

One device at the panel that guards every circuit against damaging power surges.

What you get

One device that protects the whole house

A whole-home surge protector installs at your electrical panel and shields every circuit in the house from the voltage spikes that quietly wear out and destroy electronics. We mount a properly rated surge protective device at your panel so a storm, a grid event, or a large appliance cycling on does not take your TVs, computers, and HVAC with it.

Power strips only guard what is plugged into them, and they do nothing for your furnace, well pump, or the appliances hardwired into the house. A whole-home surge protective device sits at the panel and clamps the spikes before they reach any circuit. We install one rated for your service, so the surge from a storm or the grid is stopped where it enters rather than at each outlet.

  1. Panel check and honest estimate

    We confirm your panel can accept a surge protective device, recommend the right rating for your home, and give you a clear number before any work starts.

  2. Install at the panel

    We mount and wire the surge protective device directly at your panel, connected so it guards every circuit in the house, not just one room.

  3. Confirm and hand-off

    We verify the device is live and show you its status indicator, so you can tell at a glance that your protection is working.

What does a whole-home surge protector actually do?

It installs at your electrical panel and clamps damaging voltage spikes before they reach your circuits, protecting electronics, appliances, and HVAC throughout the house. It guards everything, not just what is plugged into a power strip.

Do I still need power strips at my electronics?

A whole-home device and point-of-use surge strips work well together. The panel device stops the large surges entering the house; a good strip adds a second layer at sensitive electronics. We will tell you where that second layer is worth it.

Can you add surge protection without a panel upgrade?

Usually yes. If your panel has room and is in good shape, we can add a surge protective device on its own. If your panel is already a concern, we will tell you honestly whether it should be addressed first.
