    Just installed a Lennox G12 series furnace that was used for 1 month and then stored.
    Can I trust it? It runs smooth and is clean. Got it from an heating and colling professional.
    I know its from the 90's but its not years but the mileage--correct?

    All furnaces will run until they fail. Hopefully you will get many years out of it.
