What do I do when ductwork blocks an AHU coil removal lane?

📖 Verified core answer

Equipment needs real service and coil pull access. If a duct blocks the removal lane, hold the run and coordinate a layout shift before it becomes future demolition.

Open in Field Rescue Open category

Field verification checklist

Open or simulate opening the access door before final duct location is locked in.
Check coil pull direction and service clearance on submittals.
Measure actual clearance from duct to cabinet/service side.
Coordinate with foreman/detailer/GC if the duct line blocks removal.
Document the fix before insulation/ceiling close.

Ask foreman

The duct layout at [AHU/tag] blocks the coil/access removal lane. I checked the submittal/service side. Do you want the run lowered, offset, or held for coordination?

Text to foreman

Route options

AMake the field correction only if it is within your assignment and the approved method.

BHold and document the condition if the fix affects airflow, access, life safety, pressure class, rated assemblies, equipment, or another trade.

CBring the foreman/detailer the location, what you checked, and what decision you need before cover, startup, or rework.

Do not do this

Do not build a permanent duct main where future coil removal requires demolishing the duct.

Why this matters

Blocked service access causes expensive rework, failed inspection/punch, and future maintenance nightmares.

Final verification

Use this as field training guidance. Final direction still comes from the foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, and AHJ/code requirements.
