When the AC fan runs but there is no cooling, it almost always means the compressor (outdoor unit) is not running — due to low gas, compressor failure, or overheating.
Data Verified: 2026The indoor fan and compressor run on separate circuits. When gas is low or the compressor fails, the indoor fan keeps blowing but the air is not cooled because no refrigeration cycle is happening.
Check if the outdoor unit is running. Stand near it and listen — you should hear a hum and see the outdoor fan spinning. If silent, the compressor has stopped. Common causes: low gas, failed capacitor (₹200–400 fix), or compressor overheating from blocked airflow.
Do not keep running the AC in this state — you are consuming electricity with zero cooling benefit.

Why does the indoor AC fan run but no cooling happens?
The fan is on a separate circuit from the compressor. When the compressor stops (low gas, electrical fault, overheating), the fan keeps running but cooling stops.
Is it a gas problem if AC fan runs but no cool air?
Yes, low gas is a common cause. Also check if the outdoor unit fan is running — if not, the compressor has stopped for another reason.
