    manufacturer's capacity amount

    If the label on a condenser states 4.8 lbs, that means 4 lbs 12.8 oz right? That does not mean 4 lbs 8 oz, right? This is why I like it when Goodman states 177 oz

    That is correct , but not the proper full charge level for the split system.
    I think that is allowing for a 15’ line set , anything over that is an additional said oz per foot . How long is the line set?

    It always seemed like a giant FU from the factory. "Here you go mr. tech, we used a measurement of weight divisible by 16 and wrote it down as a divisible of 10 for you, good luck sucka!

    I find it best to charge to factory weight and then adjust superheat/subcool as needed.

    Is Goodman using any TXVs on their residential equipment yet?
    Used to be all pistons. As stated setting superheat for pistons, subcool for txv and then recording the full charge is the proper way.

    4.8 is not the same as 4 & 8 and yes;
    .8 multiplied by 16oz gives you 12.8oz
    Basic math. I think you only asked this so that you could talk up Goodman. BTW system charge on a Goodman is always incorrect because everyone has leaks from the factory.

    I did not ask this to "talk up Goodman".
