Hi Craig,  I have a home use Carrier indoor AC system with the model number is CNPVP3017ATAABAA with the intake under the main fan unit.  I have odor built up in that black foam/ insulation under the fan coil system over time and I would like to replace the black foam/ insulation piece inside the intake box (see attached image).   Is there a specific replacement parts that I can purchase online?  thank you for your help.

The "foam" that is see in the pick actually looks like a type of fiberglass insulation that is placed with stick pins.  It is also referred to as duct liner.  Since I have never actually purchased anything like that on the internet, I am not sure what is out there for sale on the net.  Another option would be to seal up the area with a duct sealant.  There are sealants out there that prevent stuff from growing.  In most cases, once the sealant is dries, it can be wiped cleaned.

I work on commerical buildings for the most part, and have yet to find anything I could not troubleshoot and repair, when repairable. I work on small 1 ton units to a 2500 ton chiller. Troubleshoot air flow, elect, and control problems. I attend regular classes to keep up with the latest and greatest.


I work on commerical sites, hospitals, gov't buildings. I can troubleshoot just about anything in the HVAC business.
