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.
