Why is my TCL Air Conditioner not blowing enough cold air?
- F
  fernandezdeborahAug 3, 2025
  There are several reasons why your TCL Air Conditioner might not be providing sufficient airflow, whether hot or cold: * The temperature setting may be inappropriate, so adjust it accordingly. * The air inlet or outlet of either the indoor or outdoor unit might be blocked; clear any obstructions. * The air filter could be blocked; clean or replace it. * The fan speed might be set to minimum; increase the fan speed. * There might be other heat sources in the room; minimize these. * The unit may be low on refrigerant; check and refill as necessary.

  If your TCL Air Conditioner is not responding to the remote, it could be due to these reasons: * The remote control may be too far from the indoor unit; move it closer. * The batteries in the remote controller may be exhausted; replace them. * There may be obstacles between the remote control and the signal receiver on the indoor unit; remove any obstructions.

Why does my TCL iQool-C2MS12K12K make running water noise?

  brandonrodriguezAug 21, 2025
  The noise of running water in your TCL Air Conditioner could be due to the back flow of liquid in the refrigerant circulation. Inspect the refrigerant circulation system for blockages.

  If your TCL Air Conditioner emits a strange odour, the air filter may be dirty. Try cleaning or replacing the air filter.
