I am getting a new central A/C unit that has seen better days. It's 15+
years old, and it finally died. I was told they have to replace something
above the furnace (the condesor?). While they are here working on my
furnace, should I just get a new furnace too??

I have a Lennox furnace that is still working, but it's 9+ years old.
Manufactured in early1993.

Of course, they are offering me a package deal to also replace the furnace
if I want. Initially I said no, but I have no idea the average life
expectancy of an average furnace. If they only last 12 years (on
average),
I hate to have them back out in a year or so.

Looking for advice for anyone that was in my situation.......



Ok..forget I am in the trade...

First thing to keep in mind...the furnace, will break. Not IF, but WHEN.
Second thing..Lennox is complete utter no longer Amercian owned garbage.
Hard to get parts, expensive parts, and in general, you can get better for
the money.

Furnaces last more than 12 years....as long as it wasnt a Lennox Pulse...
(really)

If your unit is that old, and I assume its gas, it will be more than likely,
an 80% AFUE, meaning that for every dollar in fuel you burn, 20 cents at the
least goes up the flue.
Since you are getting a new condensor(outdoor unit for the AC) and a new
evaporator (part above the furnace) does it not make sense to replace the
furnace at the same time, since the labor will be much less now, you will
get a new parts warranty, and have the benefit of knowing the systems
completely matched, and designed to work together? Look into a 94% or higher
unit. A little extra work will need to be done, like honest to God PVC
intake and exhaust flues going outside, but its well worth it long term.
