    Love for moldy ductwork and sickness

    Hello to all. After being sick for 2 weeks I have found that our goodman 4ton outdoor package unit gas/electric has broke a seam and has leaked all the rain water and what ever elce bugs etc into the heating and cooling area of the unit. Which inturn has filled the unit and ductwork full of mold. To add to it the pad which it sits on has settled and was leaning in a way that was leaving about 2 inches of water in the unit. The unit was 8 years old and is being replaced with american standard 4ton unit on a new cement pad. The ductwork in the crawl has been ripped out and I should have taken pictures of it for the wall of shame. Long story short I am wondering if someone can help me with ductwork design. I can supply the register layout and all measurements of the home and anything you might need heck I can even take pictures of the 4ft hole they blasted in the side of the foundation and never covered but with a few pieces of sheet metal hence the frogs in the crawl. I am running short on money after having to purchase a new package unit and I will end up having to do the ductwork myself. Let me know what I can do for you. I can give you a bit of money. Or? I would like a professional design. It was so hacked down there and only 8 years old. Thanks ,Dan

    The company that is replacing your packaged unit is responsible for the duct design. Read the attachment. If they're not doing a load analysis and manual 'd' duct design, you're gambling with your money and apt to end up right back where you started from. Read the attachment, then proceed as you desire. We can't give you information for DIY work. Read the site rules.

    If YOU want change, YOU have to first change.

    If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!

    I hope you are going to ask for a trunk and branch duct system with a short, hard duct return with at least 2 elbows for noise control, sealed and insulated (duct board is preferred
    NOT A HOME RUN, FLEX, SPIDER SYSTEM

    you need metal ductwork to prevent this from ever happing againg. I have seen this same thing with people over the year trying to put flex under a house & it not lasting. I can understand that $$$ is low but do u want to have to do this agian in years to come? Is this a raised frame house or a moblie home?

    Adam, I respect you right to have an opinion.
    Isn't it funny the some of the more dramatic before and after mold pictures are of metal duct? You should know that when there is LIQUID water and Organic material (Dirt or cellulose aka paper or wood) the BUGS will grow.
    Fiber glass is INORGANIC it's GLASS
    So I think your comments about "never happening again" are well meaning but not accurate

    Thanks all

    Thanks you for all the replys. I am not able to have the hvac company make the ductwork layout/design for money reasons. I am going to have to do it my self. Im sure I am able to do it. But I want to do it the right way. Any more suggetions would be great for figuring out the correct Layout and size. Thanks all again,Dan

    but knowledge is power.
    there are books you can buy for duct sizing and design
    and check what hvac companies propose against
    what you learn from educating yourself.
