What causes Car AC Blowing Warm Air?
These are the faults we most often find behind this symptom on cars driven in Hyderabad's heat and stop-go traffic:
- Low AC refrigerant (gas loss from slow leak)
- AC compressor not engaging (clutch fault)
- Blend door actuator stuck in heat position
- AC condenser blocked with leaves or debris reducing heat dissipation
- Refrigerant overcharged — too much gas can also reduce cooling

Frequently asked questions
Car AC was working fine but started blowing warm air in Hyderabad April heat — why?
April–June in Hyderabad is peak AC stress season. Marginal AC systems that barely coped in winter often fail completely when ambient temperature hits 42–45°C. Low refrigerant is the most common cause — a small leak that didn't matter in winter becomes evident in summer. Compressor clutches that slip occasionally in winter seize completely in summer heat. Metre Per Second offers free AC gas pressure check — walk in anytime.
