Air conditioner not cooling: what to check before requesting repair
A guide to distinguish simple settings from filter, airflow, drainage, refrigerant or component issues in an air conditioner.
Air coming out without cooling does not always mean low refrigerant. The selected mode, temperature, filters and airflow can all affect the result. An organised check avoids rushed diagnosis.
Mode and temperature
Check that it is in cooling mode and the chosen temperature is below the room temperature.
Airflow
Dirty filters, blocked grilles or poor airflow can make the unit appear to cool less.
Useful information
Note whether the problem is constant, whether an error code appears and whether the outdoor unit is running.
Mistakes to avoid
- Recharging refrigerant without locating a possible leak
- Running the unit hard for hours
- Removing electrical covers
