Combustion safety
Evaluate venting, draft, combustion air, flame conditions, clearances, and evidence of spillage or overheating.
Cooling performance clues
Observe outdoor airflow, condensate, refrigerant-line insulation, temperature response, filters, and distribution defects.
Use normal controls
Operate installed systems when conditions permit and disclose systems not operated and why.
Common exam traps
- Operating equipment in damaging conditions
- Ignoring soot or flame rollout
- Reporting age alone as failure
