Types of HVAC Ducts??
Looked at a nice ranch recently put up for sale. My wife swore that when
she looked underneath into the crawl space she saw HVAC ductwork which that she described as shiny black, round flexible plastic material. I have no idea what she is talking about. Would anybody reading this note have any knowledge of perhaps what she saw?? I do not have time to go back and take a look as the house is a fair distance from where we live and I would also have to make arrangements with our realtor. thanks.... |

It's Flexible Insulated ducts - when we had our house built 12 years ago we got it and found it (over time) to be as good as or better than the sheet metal ducts we had in our previous two houses! |

wrote: Care to back that statement up with some facts? Flexible ductwork is used extensively in many areas. In large parts of Texas,for example, houses are build on slab (no basements). HVAC ductwork is necessarily run in the attic space. The flex duct is both easier to run around roof framing and insulated for added efficiency. Running standard sheet metal ductwork and insulating it would be prohibitively expensive, and probably impossible with a trussed roof. We have a house on a slab with standard sheet-metal ductwork. It obviously isn't impossible, even with cathedral ceilings and a trussed roof. Actually, everyone in my neighborhood has the same. Our new house, again on a slab, will have flexible duct but it's wrapped in heavy insulation with a silver covering. The OP was describing bare black duct, I believe.

Heck both of my sons install heating and a/c equipment for a living...and in their own home they installed flexible duct runs simply because it was a heck of a lot less expensive and a LOT EASIER TO INSTALL plus it works just fine... It is true that it is a little more restrictive on air flow..BUT that factor usually is taken into account... Bob Griffiths |
