Why Is the Air Conditioner Blowing Warm Air?

Warm air from an air conditioner does not automatically mean it only needs refrigerant. Incorrect mode settings, restricted airflow, an outdoor unit fault, sensor readings or compressor issues can all create the same complaint. For a technical inspection, contact our air conditioner technician.

A proper diagnosis prevents unnecessary gas charging and helps protect the compressor from additional strain.

Frequently Asked Questions

No. Settings, airflow restriction, outdoor unit faults and compressor problems can also cause warm air.
It can help if airflow is the cause. If the refrigeration circuit or outdoor unit is faulty, a technician is needed.
If there is no cooling and the outdoor unit is not operating normally, avoid long operation to reduce compressor stress.
