Whole-home surge protection
One device at the panel that stands between the grid and everything you own with a circuit board.
Whole-home surge protection is a single device installed at the panel that clamps voltage spikes before they reach the circuits, which is to say before they reach everything in your house that has a circuit board. In 2026 that is the heat pump, the induction range, the EV charger, the fridge, the furnace controls and every screen you own.
Why this got more important recently
Houses electrified. The most expensive equipment in a Nova Scotia home now runs on electricity, from the heat pump to the EV charger, and all of it carries control electronics that do not forgive spikes. Most of it is hardwired, so it cannot be put behind a power bar even if you wanted to.
Why it comes up more here
This region loses and regains power more often than most of the province, and every restoration is a switching event. If you have had a modem, a heat pump control board or an oven panel fail for no obvious reason in the weeks after an outage, that is the pattern.
What whole-home surge protection actually does
It clamps a voltage spike coming in on the service before it reaches anything in the house. One device, at the panel, in front of every circuit.
The threat is not mainly lightning. Most damaging surges are smaller and far more frequent than that: utility switching, a nearby fault clearing, a large motor on the same transformer starting and stopping. Those do their damage cumulatively, which is why equipment often fails weeks after the event that weakened it, unexplained and out of warranty.
What whole-home surge protection involves
The device mounts at or beside the panel and connects across it, so every branch circuit sits behind it. The install is short, and sizing follows the service and what is on it.
What it does not replace
Insurance. A direct lightning strike will do what it wants.
A generator. Where the actual problem is being without power rather than being spiked, a generator is the answer and this is not.
Protection at the equipment itself. The panel device handles the big transient. A plug-in protector at the equipment you care about most handles what gets through. The two are complementary rather than alternatives.
What it does not do
It does not condition power or ride through an outage. Clamping a spike and holding a supply up are different jobs.
It does not protect what does not arrive on the service. A surge can come in on the coax or the phone line just as easily.
It does not last forever. Protective devices degrade as they absorb events. Most carry an indicator, and it is worth glancing at once a year rather than assuming.
Fitting one
Whole-home surge protection is a small job when the panel has room and a larger conversation when it does not. If your panel is full, this usually rides along with a panel upgrade rather than being worth a visit on its own, and with the panel open anyway it is the cheapest it will ever be. Ask when we are there for something else.
What will this cost?
Nobody can price this down the phone, and anyone who does is guessing. What you can find out now is what will decide the number on your house.
Common questions
Do power bars not already do this?
A power bar protects what is plugged into it, poorly, once. A panel-mounted device stands in front of every circuit in the house, which matters because the expensive victims of a surge are the things that are hardwired: the heat pump, the range, the EV charger.
Where do surges actually come from?
Mostly from inside: large motors like heat pumps and well pumps kicking on and off send small spikes through the house all day. The dramatic outside sources, lightning nearby or grid switching after an outage, are rarer and larger. The device handles both directions.
Is this worth it in Nova Scotia specifically?
Outage-and-restore cycles are exactly when switching surges happen, and this province has plenty of them. The more electrified the house, and heat pumps plus EV chargers are electrifying them fast, the more there is standing behind the panel to lose.
