Hello,
Family member has been diognosed with mild asthma. Lives in a house with hot air heating. House about 30 yrs old.
Was thinking of suggesting that they have the hot air ducts cleaned out by one of those services that do it.
But, there does not seem to be any kind of agreement as to whether this is actually a good idea or not.
Counter argument to doing it seems to be that the lint, etc. by now is pretty well adhered to the duct's wall's, and you are better off to not disturb it. Just live with whatever comes loose in normal usage, and use a good furnace filter.
Makes some sense, I guess, but ... ?
What's the latest thinking on this subject ?
Any thoughts on this would be most appreciated.
Thanks, Bob
