Why is my Tectro TS 4 Air Conditioner not cooling or heating well?
- MmatthewsericaAug 12, 2025
If your Tectro Air Conditioner isn't cooling or heating well despite airflow, it might be due to a few reasons. First, ensure the temperature is set correctly. Check the 'operation with remote control' section in chapter E for detailed instructions. Also, a blocked air filter can be the culprit, so try cleaning it. Make sure all doors and windows are closed to prevent air leakage. Check that neither the indoor nor outdoor unit's air inlet or outlet is blocked; clear any obstructions and restart the unit. It’s also possible the compressor has a 3-minute delay protection activated; if so, simply wait. Finally, the outdoor unit may be defrosting.
