Does the AC fail across its served rooms or only in one space?
When one room is warm, compare it with other rooms cooled by the same equipment. A local airflow, load, or control issue can persist even if the outdoor unit operates correctly.
Record simultaneous temperatures, active mode, door positions, and available cooling model information. Note whether air delivery is weak or merely warmer than desired.

Assessment and Scope
Questions for the Proposed Work
01
Identify the served spaces
Central registers and ductless heads have different delivery boundaries. Ask which equipment actually supplies the room before connecting the symptom to a compressor or refrigerant fault.
02
Assess local and shared causes
The contractor should distinguish room airflow and loads from controls, coils, electrical, or refrigerant findings. Equipment measurements may be needed where symptoms are system-wide.
03
Compare useful corrections
Ask whether balancing, duct changes, sensing, repair, or a separate zone meets the objective. Nominally larger equipment is not a universal answer.
Compare the next step
Choose the next step from room observations and confirmed system findings. Request an explanation of how the accepted scope addresses the uncomfortable space without assuming all cooling equipment needs replacement.
Do not open electrical panels or handle refrigerant. If ice, water near electrical equipment, or abnormal operation is present, stop using the affected system and request an assessment.
