brought forth from the murky depths:

A friend is purchasing a new furnace and is leaning towards the Lennox
G60 (medium effic., 2 stage heat). She has heard however that Lennox
reliability has declined over the past few years and is therefore not
recommended.

We (in SW BC) have had Miller high efficiency condensing for several
years. Had a noisy blower but it was replaced under (5yr) warranty. If
your friend is doing a new installation consider that even medium
efficiency requires a class B chimney going up through the roof. The
high efficiency brings in combustion air and exhaust combustion products
through plastic pipes in the joists (basement ceiling, main floor) going
to and through the side wall of the house. No holes in the roof and
other advantages.
