Madison Park

If this isn't the right place for this question, the moderator is more than welcome to delete it.

Our homes in Madison Park are mostly 50-odd years old, many built over crawlspaces.  They've been retrofitted with air conditioning, with the coils and ductwork located in the crawlspace.

I'd love ot hear how my neighbors are handling sweaty ductwork during these humid summers.  I have pools of water standing on the vapor barrier under my house.  The uninsulated fabricated metal ducts have all been replaced with new insulated flex ductwork, but the problem is still there.  I was under the house yesterday, and water is streaming off of the ducts onto the 6-mil poly on the ground, and gathering there in puddles. 

There are lots of services offering to solve the problem, using any number of techniques, all of them adament that the other guys will ruin your house.

Has anyone successfully solved the problem?  How did you do it?  I'm not looking for contractors offering to fix it for me.  I'm looking for a good solution that works in our area.  Then I'll find someone to implement it.

I'm guessing I'm not the only one with this problem in our neighborhood.  A good discussion here may help more than one family maintain their home and head off water damage, mold and insects. 

Thanks in advance for any experiences, opinions and/or anectotes on the subject -

I had my ducts wrapped under the house,  and it made a huge improvement.  My crawl space use to look like a rain forrest.   One with pink cotton candy as I had insulation under the floor boards.

I also had a barrier on the floor. 

A county inspector suggested it to me when they inspected my new heating system a few years ago.  It also made my utility bills cheaper.

Good luck!

Prior to that I use to use a window fan under the house during the summer.  It helped some..this duct wrapping worked the best for me.

More insulation makes sense to me.  The problem is cold ducts meeting humid air.  The answer?  make it harder for cold and humidity to meet -- by insulating!  I have brand new insulated flex ductwork down there.  R8, I think the guy said.  R8 sounded kind of flimsy to me, but I agreed to it -- not knowing any more than I do about available material for a/c ducts.  Now I'm thinking the gig may be to upsell to a sealed, dehumidified arrangement.  I wonder if insulated flex ducts can be wrapped in insulation?  or will they sag?  They're already kind of big & poofy.  It was way easier to move around down there with the old fabricated metal ducts.

I've also seen the box fan advice.  I'll try it.

I've also considered grading my crawlspace floor toward a sump pump.  Does that sound completely loony?

Thanks for the ideas.  Anybody else have this problem or ideas for solutions?
