We just had a Carrier central AC installed (just AC with indoor air
handler) and have a lingering odor present in the two rooms with
exposed ductwork. The odor started during install, before turn-on, and
smells rubbery or "fish" like. It's been almost 2 weeks and running the
AC does not help. The curious thing is that there is no odor in the
duct outlets, or other rooms, which are air-conditioned. Could duct
lining in the return, or duct sealant be causing this problem?

I am pursuing this issue with the HVAC company (a well respected one)
but would appreciate any expert opinions.

Don't x-post this **** to alt.hvac

The answer to your question is yes. Duct sealant and or duct insulation could
be causing the smell. I doubt its the duct lining in the return, as you would
smell it then from every supply outlet. You might investigate which duct
sealant was used for your install.

fyi, a new roll of FSK duct wrap smells a lot like cat ****.
