Why can same-size equipment force a ship redesign?

Different hose and power-connection positions can make a similarly sized replacement unit require rerouting, with repeated changes adding up across a ship.

Question

Why can replacing air-conditioning units with others of roughly the same size still force changes to a ship?

Short answer

The intake hoses and power connections can be in different places. Rerouting services for repeated substitutions turns small interface differences into a substantial redesign.

Notes

Air-conditioning units of roughly the same size can still require different ship connections. Moving the intake hoses or power connections means rerouting the services that reach the unit. Repeating that substitution across the ship accumulates changes to its internal arrangement. The Constellation example shows why nominal equipment dimensions alone do not establish that a replacement will fit an existing modular design.
