Do HVAC system drawings always provide exact routing, mounting, or location information?

HVAC system drawings generally do not provide exact routing, mounting, or location information. The drawings typically illustrate the design intent and layout of the HVAC system rather than detailed specifications for installation or precise physical locations of components.

These drawings serve as guides to communicate the overall system design, including the types of equipment used, the general arrangement, and connections between different parts. However, actual installation may vary due to site-specific conditions, such as existing structures, clearances, and local codes that could affect how equipment is mounted or routed.

Choosing whether a drawing should detail exact locations and mounting can change based on the project requirements and the phase of construction, but in general practice, HVAC designs will not cover every detail required for installation.
