Intro: Warm air from the AC is usually caused by low gas or a simple blockage.
1. Low refrigerant
Most AC systems need reβgassing every few years.
2. Blocked cabin filter
A dirty filter reduces airflow.
3. AC not used often
Seals dry out and leak gas.
4. Fan issues
If the fan is weak, the AC feels warm.
5. When to get it checked
If itβs warm even after reβgassing.
Summary: Most weak AC is caused by low gas or a blocked cabin filter.
