I have a HVAC duct that is almost totally blocked. It has
been this way since my home was constructed. I suspect a crimped vent
or trash in the vent. The problem is the obstruction appears to be a
good distance away from either end. I have easy access from the
basement and from the second floor outlet. In between those is a long
run with several 90º elbows.

I don't want to start tearing up floors and walls to correct
the problem. I am looking or suggestions. I was thinking of a camera
that could be snaked through the vent. Since I don't know which way
some of the turns may be just snaking a standard snake would not
likely be really helpful

Suggestions? Sources for a rent a camera?


*When doing some remodeling on homes, townhouses and condos I occasionally
notice that some ducts from the original construction are sometimes a little
crushed. However what I find more often is that duct connections are
separated.

Good point. I don't know why I did not think if it myself I
have seen it more than once.

Some of them were just shoved together without screws or foil
tape and they came apart for whatever reason. Sometimes in attics I see
flex ducts that are flattened from tradespeople and homeowners climbing over
them. I have also seen flex ducts that have holes chewed in them from
rodents.

Check out plumbing supply companies. You may find one that rents a camera
or perhaps they can refer you to a company that does.
