I'm the victim of a Lennox G27M install.

EVERY PART, from the blower motor to the gas valve, has been replaced
at least once.

I've long since lost count of how many control boards have been
replaced.

Don't buy Lennox, and don't buy from whoever makes Lennox. Don't drive
near a Lennox factory, and if your friends have a lennox system, don't
go to their house (Youll probably get legionaires disease there). If a
Lennox advert comes up on TV, change the channel. In fact, sell the TV,
as after showing a Lennox ad, it's probably going to break down soon.
If someone tries to sell you a lennox system, throw them out of your
house. If your neighbor has a lennox system, build a high partition
wall betwen your house and theirs.

Don't look at any lennox equipment, it will impair your vision
permanently. Don't say 'lennox', you will probably get throat cancer.

There used to be a sketch on SNL where someone would proclaim: "If it's
not scottish - it's crap."

Let me assure you, when it comes to heating systems - If it is
scottish, or if a company called lennox uses a scottish theme, (or was
it Irish), IT MOST DEFINATELY IS CRAP.

Other than that though, Lennox is wonderful. It's especially good for
draining bank accounts. Also, it will afford you the opportunity to see
how well the company that selss the CRAP to you will stand behind their
product.

You WILL get to know the techs from the install company on a first name
basis, assuming that company isn't out of business. This is especially
nice in the middle of winter when you come home to an 2500 sq ft walk
in freezer - it's harder for them to be upset when you know them so
well and you have both long since agreed that the equipment they sold
you is CRAP.
