    I am in an area once dominated by lennox i see them all the time. they can be intimidating at first but are not that bad. with a little torch work you can make your own wrenches for removing igniter and flame sensor. biggest thing i run into is ignition modules failing and ripped air diagphram

    I work on a lot of them yet. Its a shame they had to quit making them. There still is not a more efficient forced air furnace out there.

    They are very simple once you know the basic concepts of how they work. Just carry a board, air flappers and some spark plug wires.

    The last pulse furnaces produced are now over a decade old, and Lennox is phasing out parts. The heat exchangers have been gone for years, but now the gas flapper valve is down to remaining stock only.

    OH yeah. I go on call in 3 weeks. I fully expect the little blue haired old ladies to start calling in the middle of the night.

    It's cold in here, thermostat says 70 degrees.......

    Still a few around here. Kind of a pain to work on, the burner that is.

    A few years back, in the mid 90's, I had a service manager ask me if I had any applications where one of these new condensing Boilers called the Lennox Complete Heap would fit the bill!!!
