Why it does not pay to wait
A single surge from a storm or a grid event can take out everything hardwired at once: the HVAC control board, the oven, the well pump, a smart panel. A plug strip protects none of that. The gear you lose in one event costs far more than the protection would have.
Power strips protect one device. They do nothing for your HVAC, your oven board, your garage door, or the LED drivers in your ceiling. A single surge from a storm or a utility switch can take out thousands of dollars of electronics in an instant.
We install a whole-home surge protective device at the panel. It clamps the spike before it spreads through the house. It is a small install with a large payoff, and it pairs perfectly with a panel upgrade.
What a whole house surge protector installation includes
- Type 2 whole-home surge protective device at the panel
- Point-of-use protection for sensitive equipment
- Proper grounding and bonding verification
- Coordination with a panel upgrade when needed
- Status indicator so you know it is still protecting
What you can check yourself first
Before you call, here is what you can safely check on your own. Even if you still call us, you will walk in knowing more than you did.
- List the expensive hardwired gear: HVAC boards, oven, well pump, smart home panel.
- Check whether you already have any surge device at the panel.
- Note if you are on a line that flickers or browns out during storms.
- Keep power strips for the electronics, and ask us about the panel-level device that protects the rest.
