I want to get a new Bryant high efficiency furnace to replace the old Lennox
one (maybe 35+ years). But the current furnace has an AC (evaporator C16 &
outdoor condensing unit HS18). I wonder if it's ok to use the old AC with
new Bryant furnace?
BTW: I also have a quote for a new Lennox furnace (5-year labor warranty),
but it's $1500 high than the Bryant one (but only 1-year labor). Is the
Lennox one worthwhile?
I'd suggest to get the Bryant, and bank a couple bucks for emergencies.
As to using the old AC, it should work. Of course, they will try to sell you
a new one. The old ones are less efficient. But, the tech should take the
cover off the old one, clean it with water and chemicals. To strip the
exterior coils and fins clean. The evaporator may also need cleaning.

Id suggest someone strip you down to your birthday suit, give you a
good chemical cleaning with muratic acid followed by a caustic
solution paste bath and then a good belt sanding with 80 grit paper.
Maybe, just MAYBE THEN you'd shut the fuck up.
I spent several years as a HVAC installer. Most of the time, it's possible
to install a new furnace under an existing AC without too much trouble. Some
sheet metal work.
However, during a furnace install is a good time to clean the evaporator. A
good HVAC guy can pump the freon into the condensor, valve it off, and then
remove the evaporator for cleaning. It's also very possible the evaporator
will come out enough to clean it with the freon tubes still atached. It's
specific depending on your installation situation.

Painfully obvious you've never done any of the above on your own and
especially not correctly.
Maybe a belt sanding to the front of your face and not stopping till
it makes its way all the way through to the back of your skull.
Then a good skull fucking from an elephant should top you off quite
IMHO, Lennox is overpriced,overengineered,proprietary crap,
sure it works , But Dave is Awfully proud of it ;-)
around here we call em "lemonexs"
im sure i'll spark another debate about which brand is better
but the key thing to remember is the installation is the key to longevity
the worst brand properly installed will last longer than the best brand
id get some more quotes . and look into some different brands as well
and i would seriously consider getting new ac while you are at it
it will be much easier and cheaper to have it replaced now than later
besides the unit have now is not much better than 8 seer ,and im gonna guess
close to 12 years old
dont make much sense to slide a brand new furnace under a twelve year old coil
but thats your decision to make , maybe your in a part of the world where you
only need ac two weeks a year ;-)
shop around some more
In my humble opinion, I would replace the entire system, get the 10 year,
extended parts and labor warranty. There are several other brands out there,
that I feel are better quality. Do some more shopping around... A correctly
sized, properly installed system will save you a lot more money in the long
run. No its not going to be free, or even cheap....but you will get what you
pay for in the form of quiet, efficient, comfort.
