We replace the linesets when ever we can. The cost of a reaplcement lineset can run anywhere from $600.00 upwards to $1,100.00 which is added cost to the homeowner.

I just had my system replaced with a 410a system and there was no way I would have allowed them to re-use the old lineset.
I'm sure it can be vacuumed to manufacturer recommendations but as a homeowner, it's not worth the worry. Get a new, clean set-up.
