You're likely to be screwed either way, if the lineset isn't large enough
for the new high S.E.E.R. equipment.


In our area, I'm beginning to notice a few common trade practices (that
might be unique to around here), and wonder if you could flesh out the
reasoning for one of them.

Except for slab construction, I've noticed that nobody seems to use
chases or conduits through which to run linesets. I've even seen a few
cast right into slabs without the first bit of pipe around them. It
seems to me that some 4" or 6" thinwall waste pipe would be a great
investment toward future upgrades. For any set shorter than 100', it
would be pretty inexpensive, too.

Gotta love it when the lowest bidder gets the job

I have seen a lot of water in the couple of grade-level or below-grade
sets I've pulled out of conduit, and suppose that might be one objection
to using it. (Ken _likes_ it that it's my hands and not his in that
stagnant goop...)

There is a reason that your supposed to seal both ends of the chase

Are there other reasons - besides the basic cost of materials and labor -
that make conduit/chase installation of linesets undesirable?
