Wait, you think most sites have that much left? I've worked on a few digs and honestly, the good spots are usually picked clean by pros way before we get there. That hollow tile thing is a crazy lucky find, but it's like winning the lottery. Most of the time, you're just moving dirt that's already been turned over a bunch.

Actually, that's a risky method if you're not super careful. A utility knife can cut too deep and damage the copper. I've had better luck with a proper wire stripper for control.

Yeah, it's crazy how we can get stuck on pushing harder... when sometimes the best thing is just to slow down and listen to what our body needs.

It's just brisket, not a science project.

MERV 8 is for the return, not the intake side.
