Use the safest available access path to inspect the entering-air side of the evaporator coil.
Preserve the condition and explain only what this action actually supports before moving to the next action.
TA-14 ACADEMY // 14-STEP FIELD GOVERNANCE
04
Evaporator Coil Inspection
Show the coil — do not merely talk about it
Inspect and visually preserve the evaporator condition from the air-entering side whenever safe access allows.
WHY THIS STEP EXISTS
The Academy treats this step as proof: the air-entering side of the coil is a critical airflow condition and should be shown, not guessed.
01
TECHNICIAN MINDSET
How to enter this step
This is visual evidence, not a sales setup.
The homeowner should see what the technician sees when practical.
Access limitations must be documented, not hidden.
Appearance alone does not establish refrigerant charge or a health conclusion.
02
FIELD PROCEDURE
What to do — in governed order
Use a flashlight, phone camera, or appropriate inspection tool to capture a slow, clear view when access permits.
Preserve the condition and explain only what this action actually supports before moving to the next action.
Look for debris loading, crushed fins, corrosion, oil staining, standing water, drain-pan condition, and other material restrictions.
Preserve the condition and explain only what this action actually supports before moving to the next action.
Review the captured condition with the homeowner and explain only what is actually visible.
Preserve the condition and explain only what this action actually supports before moving to the next action.
Determine whether the condition supports additional cleaning/service discussion within scope, without jumping ahead to unsupported work.
Preserve the condition and explain only what this action actually supports before moving to the next action.
03
HOMEOWNER COMMUNICATION
What to say without outrunning the evidence
SCRIPT 01“Rather than tell you what I think the coil looks like, I want to show you the side that the air actually reaches first.”
SCRIPT 02“What we can say from this image is what is visibly present. We’ll keep that separate from anything that still needs measurement.”
Communication boundary
Use plain language, show the evidence, and avoid fear, certainty, or a recommendation that the current step has not earned.
04
STOP CONDITIONS
What you are not doing here
BOUNDARY 01
Do not call the coil dirty without evidence.
BOUNDARY 02
Do not clean away the original condition before recording it.
BOUNDARY 03
Do not force cameras or tools into unsafe access paths.
BOUNDARY 04
Do not bypass or disturb safety controls carelessly.
BOUNDARY 05
Do not use fear language or diagnose refrigerant condition from appearance.

STEP EXIT GATE
This step is complete only when:
✓Coil viewed where access allows
✓Condition shown to homeowner
✓Evidence preserved
✓Any cleaning decision remains tied to documented condition
