A friend is in her basement and talking to me on the phone and she

It's an expensive house built about 10 years ago.

She's sent me two pictures.

One is of two parallel 2-inch white plastic pipes next to each other
that are going horizontally across the ceiling, have right angle curves
that point the pipes up, have 2 or 3-inch straight pieces, then right
angle curves that point through the wall to the outside of the basement

You can see a floor joist from the floor above and the silver-colored
insulation on the inside of her basement wall.

(Do they now enclose the high and low pressure AC hoses in PVC pipes
like this?

Not that I've ever seen, that's for sure. The lines are copper tubing,
less than 1" not 2", covered in black foam insulation on the low
pressure side and how can PVC glow? No idea what you're looking at.


Sounds like a light behind a PVC pipe lighting it up.
