    I have a 16 year old unit that needs about $500 of parts and work.

    I am having trouble getting the parts from Lennox and am considering replacing the furnace.

    My contractor said the average life of this unit is 12-15 years.

    Looking for advice

    Go with something new and get yourself a good warranty.

    that furnace has a life time heat exchanger warrenti for the original owner and 20 years for owners after.

    it is also the highest efficiency ever. 97 percent
    it is one of the most reliable furnaces made as long as the company working on it is trained for it.

    12 to 15 years is not a correct statement when it comes to the pulse furnace and to replace it would be a step down

    now with that beeing said it is your call as far as repair or replace.

    the heat exchanger needs to be pressure tested every two years and if it ever fails you will get a new furnace from lennox and just pay shipping and labor as long as you are the first owner and up to 20 years if you are the second owner

    Just one question. Why did they discontinue the pulse furnace?

    Like anything else cost.
    Lennox can build 5 G50 furnaces for the cost of 1 pulse heat exchanger.

    Also in the market place you can get a 90 percent furnce for two thirds the price of the pulse so most home owners would go with the least expensive unit thinking the 3 or four percent lose was more cost affective.

    pulse lost the market because of cost

    Hey Tin
    wasn't the g26 offered as a replacement furnace also to get the public away from the lennox pulse.
    The pulse and the problems that the secondary h.e. would have cost lennox millions in future cost for replacement.

    I think that boiler uses pulse technology too.

    yes wpg is was the g=26 and now it is the g51
    and it was offered because they were no longer making the pulse heat exchanger. Again because of cost the furnace was cheaper for lenox.

    also there was only a 1 percent failur rate on the pulse heatexchanger pryor to 1990 and when you think about it what is the rate of all the other furnaces on the market from the 80s.

    apples to oranges the pulse still has them beat imo

    i think lennox should bring it back

    Hey dude, do you have some kind of brain damage or something?

    As for your question; I dont do alot of installs. Mostly service, and change outs in both residential and commercial. This time of year is slow, or havnt you been in the field long enough to figure that out. I can get calls at any time, day or night. Since I am the boss, I choose when I feel like moving.
    Now, go sit in the truck and quit tugging at my shirt tails like some slobbering kid.

    Good point Tin.

    I was more involved in the pulse program in the mid 90's.
    Where i changed ruffly 300 h.e. in a span of a year which fail thier pressure tests.

    I wasn't old enough to be a tech in the 80's...
    NO INSULT MEANT.!!!!So not really up to date of the fallier rate during those times.
