@moto_man so sorry to hear this! Wow! You’d think the whole house surge protector would keep everything safe as kittens. Though I did just kind of recently discover they only last about 5 years. I had no idea I thought they were good forever. I’ve had mine for 7 years now…
Thanks for sharing about the Shunyata. It had to be the difference, what else could explain it? I’m in NH and we don’t get anywhere near the heavy duty storms like FL. But we get our share…great to hear your system is in tact sorry to hear about the HVAC…good luck, hope it’s not too costly to repair…
