    Furnace may be derated t by 20% although the out put is not grossely oversized to meet your needs as it is equipped.
    Those TFC/Meridian furnaces are pretty versatile

    Lennox has 60 blowers on some 90,000 models.
    Mind explaining what problems you refer to?
    Ive seen furnaces from the factory that were plugged so I have to disagree with you on this one.

    Factory may be installing a restrictor plate in the inducer.

    When you plug an orfice on a furnace with a draft inducer. You cool the flue gasses down, and can cause condensation problems in the flue.

    Ittook me almost four seconds to find out that york makes an 80000 btu gross input unit that has a 2071 cfm capability at .1" external static. i would gues every other manufacturer has similair if they actually open the book. You could also look at variable speed stuff from york, luxaire, probably trane, lennox, etc. shouldnt be a big deal.

    My current hot air furnace puts out a full 1 gph, or 139K btu gross and 111K net, after deducting 20% for efficiency loses.
    I think he has an oil furnace.

    Indeed I do have oil. I have debated ad nauseum oil vs. propane.

    I do in fact have an oil furnace. Still thinking about propane, but have all but ruled it out after research showed oil to less expensive than propane for all but the last 2 or 3 of the preceding 30+ years. Not good odds for the future, I'm afraid.

    The most puzzling part of my HVAC issues is the lack of consistent answers. Hard to get a firm handle when even well reasoned minds can differ.

    Yes look for a furnace with better then average static capability.

    However the duct system may need remediation.Often the "fittings" and elbows close to the furnace are the culprit,eating up much of the static ability of the furnace,Use low loss fittings and turning vanes in the elbows,properly sized return drop,maybe return air duct to both sids of te furnace.

    Every bit as ,if not more, important then getting the furnace with the highest static ability.
