Thread: Job interview ?

    Job interview ?

    Went on a job interview and was asked how do you set the fan speed on a Lennox variable speed furnace?
    Also another one was what is a bisbor? Never heard of such a thing..

    Thought these were both trick questions..

    fan speed

    Here is what I would have answered.

    Same as any other unit. Set heating speed to maintain rated temperature rise.

    Set cooling speed to meet required cfm for cooling load (generally 400 cfm/ton) based on TESP of the unit and a fan curve, or drop across a known load such as a coil.

    Every high end fancy POS furnace has a different way to physically set the speeds. Some have dip switches, some have moveable jumpers, but they all ultimately do the same thing.

    As far as a bisbor, either that was a typo, or a test question.

    I've never heard of it either.

    A "bisbor" is how a guy with a sinus infection describes an unsatisfactory job.

    "Dad guy who bixed by burnis did a bisbor job"....
    Technical incompetence is NOT a sales tool....
