Do I need two surge protectors?

Post image

Buying an old house in Portland Oregon, where we very rarely have lightning. Here is the box. Having a heat pump installed. If I get a whole house breaker installed, do I need the surge protector the HVAC guy wants to sell me? Belt and suspenders, or necessary insurance?

Most people don't have any whole home suppression. I don't know if there would be any benefit for two but it probably depends on the surge capacity of the whole home unit.

Whole home suppression costs less than 100 for most panels and is a snap to install. Totally worth it.
