Sound Familiar?

You're standing in a mechanical room trying to remember the economizer enable conditions for the third time this week
Every commissioning job, you're rebuilding your checklists from scratch instead of working off proven templates
You Google "VAV troubleshooting" and get 50 pages of theory when you need a 30-second flowchart
You know the sizing rules of thumb exist somewhere in your notes from 3 years ago, but good luck finding them
New techs keep asking you the same questions: "What's the Cv formula again?" "How do you wire MSTP?"

Sample: Troubleshooting Flowchart

SPACE TOO HOT?
Is the system in Occupied mode?
  NO → Check schedule. Override to Occupied.

Is the thermostat reading correctly?
  Compare to handheld thermometer. Off by >2°F → Recalibrate.

Is the VAV box calling for cooling?
  YES → Is the damper responding to command?
    NO → Check actuator: power? linkage? stroke?
    YES → Is airflow at maximum?
      YES → Is discharge air cold enough?
        NO → AHU issue. Check CHW valve and coil DP.
