Refrigeration Piping Blocks the Planned Duct Route
Document the conflict and compare the current mechanical, refrigeration, and coordination drawings before moving either system. Refrigeration piping may have slope, insulation, valve-access, and replacement-path needs that are not visible on the HVAC plan.
Do not crush refrigeration insulation, trap valves, or field-offset the duct solely because the piping was installed first.
Check
Identify the exact grid, elevation, duct size, and conflicting refrigeration lines.
Check the latest coordination and refrigeration drawings.
Verify insulation thickness, valves, supports, drains, and service access around the piping.
Show the conflict with photos and measured elevations.

Say this to your foreman
At Grid [location], the refrigeration lines occupy the coordinated duct elevation. I checked both current drawings and measured the conflict. Do you want the duct route held while the trades re-coordinate this area?
