I apologize for the lengthy delay on the reply to this, but today's the first day I've been able to settle down to take care of any responses because of being backlogged by two days, thanks to losing power twice.
It was going on in just my front room's box, but it resolved itself it seems. I don't know what was going on, but it seems fine now. It might have been from the fact that we lost power about a week before that briefly, because we lost power again, though this time was for a lengthier time.
As for the brand new wiring, the tech ran new wiring because this house is completely brand new, custom built. He had to drill for new wiring and all. (He was here for the full 3 hours and 45 minutes that they told me it would be.)
