We are homeowners, not HVAC professionals. This page documents what we observed in the attic.

The Issue

The flexible fresh air intake duct has pulled away from the exterior wall collar and is hanging loose in the attic. The duct now terminates inside the unconditioned attic space rather than connecting to the exterior.

Timeline

• April 2025: Discovered detached duct in attic during inspection.
• April 2025: Opened warranty claim with CBH.
• April 2025: Applied temporary fix (tape and clamp) until permanent repair is scheduled.
