We are about to buy a home and just discovered that the heat/air duct work is something called "sonatube" or "sonic tube". We've been told it is compressed cardboard with a thin aluminum foil liner. It runs under and up thru the slab foundation. The home is 23 yrs old. We have been told there is a danger of these imploding, thus blocking off air ducts. Our questions: has anyone heard of this? What's the estimated lifetime of this type product? Is there any way to replace this without tearing up the slab? The rest of the house is structurally in very good condition. And the lot drains well, no problem with pooling anywhere after a hard rain.

Implosion of this product is not a suitable word. Collaps is more like it and then it would cut off the air supply. It is rated for about50 years provided the material stays dry. There should be no reason to remove the runs unless you notice loss of air flow. If you had to,...Remove it if that is possable the concrete would provide the identical shape as the heat run did. Try not to worry about collaps of the tube. It should give years of trouble free air flow.
