Air conditioning not cooling
Loss of cooling can come from airflow, controls or sealed refrigerant system issues.
Understanding the symptom
Loss of cooling can come from airflow, controls or sealed refrigerant system issues.
Possible causes to investigate
Cabin filter restriction; condenser fan issue; refrigerant leak; compressor or control fault.
Safe observations
Check settings, filter and whether fan/blower operates; request refrigerant leak diagnosis.
When to stop and get help
Do not vent refrigerant or bypass pressure protections.
A symptom alone cannot establish a physical diagnosis. Arrange competent inspection where safety is uncertain.
