   There's such a thing as a "whole house" surge protector -- attaches to the breaker panel.

   A strong nation, like a strong person, can afford to be gentle, firm, thoughtful, and restrained. It can afford to extend a helping hand to others. It's a weak nation, like a weak person, that must behave with bluster and boasting and rashness and other signs of insecurity. --Jimmy Carter

   The last EMP/lightning job I did for a missile site I used the epcos MOVs shown above.

   Install 1 on each line with absolutley minimal lead length as close to the best ground you have* (probably near or in sevice entrance)  Run the wires from the breaker TO the MOV, then on to HVAC.  Do NOT just run a long lead from the MOV to the breaker.

   Dont just tie one side to the box either, tie it to where the main ground conductor comes into the box.

   *Edit.  Even better, run your HVAC line from the service panel to a new small box right at the ground rod or metal water pipe coming into the house, install the MOVs there.
