    Your making a straw man argument. Not all 2 stage furnaces, installed with single stage t-stats, work the way that you described. Upstaging is not simply based by timing. It is logic based.

    Yes you will have more heat exfiltration on larger duct work, but that is not going to amount to anything significant. The duct work needs to be sized to move enough air for hi fire.

    What's the model no of the furnace? Some 2 stage furnaces can be installed with a 1 stage t-stat and still operate as a 2 stage furnace if w1 and w2 are jumped together. When the control receives a...

    I very much doubt that either the name plate charge is wrong or that you added over the name plate. I suggest "measuring" the air flow before concluding that the hi pressure is due to an over charge.
