Overview of G32
As a member of Lennox's Elite Series of furnaces, the G32 is a discontinued mid-level furnace offering up to 94 percent AFUE. According to information from its introduction in 2001, this model features two-stage heating, meaning it was designed to consistently operate on a lower heating level until the system detects a change in the temperature. Benefits of two-stage heating include even heating throughout the home, reduced energy usage and increased temperature regulation, according to the manufacturer.
Additional components of the G32 include a low speed continuous fan operation setting for increased air circulation, an insulated blower motor compartment designed to reduce operation noise, and a two-stage gas valve that quietly adjusts the levels of gas depending on which stage of heating is operating.

DISCONTINUED & DISAPPOINTED WITH LENNOX
I have a 13 yr. Old g32q3/4-100 two-stage furnace with a/c unit in my
2,000 sq/ft two story home. Serviced regularly, about 6 months ago the
entire blower unit had to be replaced ($650) and now both of the lower
circuit boards and wire harness are melted due to some unknown cause. I
had to shut power off to it at my main power box to avoid fire & thus,
the entire hvac system id without power & inoperable.
Now I am told by two different authorized Lennox Dealers that Lennox has discontinued mfg. of this series as well as the old Pulse models. That means that Lennox is also not making replacement parts. Even if parts would be available the repair would be nearly $2,000.
I will buy a new unit and it will not be another Lennox.

1996-2013: use->7 yr heavy, 10 yr minimal
We have a shared large house and a serious woodstove so gas furnace
usage has varied. I had to replace the igniter electronics module
($140cdn) after year 15, and the blower control module ($124cdn) just
went now. An technician would likely have doubled the module cost and
charged $200/visit for a total of $728. I'm not impressed, since unlike
moving or arcing or heated parts, electronics only blows when it is
wrongly designed, and Lennox brochures are so glossy. Amazingly, The
moving parts and igniter are original. A condensate trap did leak and I
had to liberally silicone it. If the furnace was built for $500,
wholesaled for $1100, sold to me for $1800, and I paid $500 for the
install then the summary is all these furnaces are so cheap it is luck
of the draw if they last, and how does "using a reputable installer"
change the basic quality of the unit. I have read the service manual for
my machine because it interests me, and see that most failures people
have can't be due to installation, but just the cost squeezed quality of
the box. Apparently Lennox owns "Allied Air" which owns Ducane,
Concorde, ArmstrongAir, and AirEase. And an installer told me this
evening some larger bought Lennox. All these fake "brands" have so
debased my trust that I have none and am confused what next to buy.

Lennox Warranty Worthless. Local Dealers Will Not Honor Warranty On Heat Exchanger. Controlled Comfort (Dealer)
They installed my furnace in 1997. The system had a lifetime warranty on
the heat exchanger. The heat exchanger is leaking carbon monoxide into
my home and had to be shut down. When I called to enforce the warranty,
controlled comfort basically told me my warranty was worthless and tried
to sell me a new system. Lennox told me they have no recourse in making
their dealer honor their warranty. That they are all independent and they
can decline the work. What kind of warranty is that?

Not real happy
This furnace was installed in August 2003. I change the filters
regularly and blow out the air lines every couple months. No matter what
I do, this furnace has to be serviced every year. And usually on a
Holiday or weekend. The company that installed it said we must have the
furnace and a/c "tuned up" once a year or it voids our warranty. Called
Lennox this morning and they said the same thing. But nowhere in our
paperwork does it say we have to have it serviced once a year for the
warranty. This is total bs. We dropped about $12k between the 2. Now we
are supposed to spend another $160 a year for "tune ups"? I would not
buy another Lennox for sure.

Been a good furnace
I have had no problems until now after 10 years. The combustion blower
motor went out. A reasonably priced replacement can be easily found many
places on the Internet. My first concern was a circuit board failure
when the furnace was installed because I kept hearing of other peoples
furnaces failing from dead circuit boards. Not this one. A tip a Lennox
dealer said was to blow out the small tube from behind the top access
door. Pull off the tube from the left rubber piece and blow into the
tube. a 't' fitting can plug and cause water to get in the fan area
causing failure. I suggest pouring a lean bleach mixture into the tube
and flushing it if repeated problems occur.

Not Worth It
Had a 98% efficient Lennox Signature Collection model g32v3-75-5
furnace installed in June 2003. In October 2008, four months after the
warranty expired, had to replace an ignitor and fuel valve to the tune
of $800. In March, 2009, had to replace a circulator fan module for
Neither the installer, Apollo Heating Inc., Schenectady, NY nor Lennox Customer Service in Dallas, TX, (and the CEO) would respond to inquiries for consideration/extension of warranty coverage. In fact, absolutely no response was received despite sending two letters.
Absolutely will NOT recommend a Lennox furnace.

Water sounds in the Fan
Water sounds in the fan which caused the g32 unit to quit. I have
called Winnipeg Supply for several calls, but they can not find the root
cause. So far all I do is spend money on last minute calls when the unit
fails. Never buy a Lennox.
Other G32 Reviews
Lennox and the G32 receive mixed review around the web. Contractors on hvac-talk.com regard Lennox products as quality equipment, but then note the amount of troubleshooting issues they have with the brand. Several professionals state that they frequently receive service calls for Lennox products and the company isn't proficient at developing the solutions to system issues until after the problem is identified.
These contractors also cite experiencing problems with several components of the G32, including the inducer and roll-outs. These reviewers advise cleaning this unit out frequently to prevent problems, as the piping and internal system are susceptible to accumulating debris and access buildup.
In turn, homeowners on hvac-talk.com post troubleshooting problems with the G32, including trouble with the system wiring and recurring failures and service calls.
The G32 is available in different models which vary in efficiency and capacity.
