I would say it's ridiculous, if one is even still available.
Have you looked at tax credits, utility rebates, etc available
that reduce the cost of a new high-eff system? Those can make
a high eff one cost the same or less than a 80% efficient one.
Calculated how much a year you will save in gas and electric?
AC involved too? How much you will save per year with a 14 SEER
instead of a 26 year old that may be running at 8?

Hey, I had a Lennox dealer out last night and he strongly discouraged a HE
because the machine is going in an interior closet and the PVC pipe(s)
would have to pass through about 3-4 ft of unheated attic crawl space.
Said the condensation could freeze up. He was pushing an 80% but with
variable valve and DC variable blower. The Carrier / Payne dealer did not
have any issue with with the piping situation.

I may just say screw it and get a simple 80% and call it a day. Not doing
new air at this time.
