If your Riello Air Conditioner isn't providing enough cooling, start by checking the filter. A clogged filter can significantly reduce performance, so cleaning it can help. Also, make sure that nothing is blocking the airflow to the outdoor unit. Obstructions can impede its ability to dissipate heat, so removing any obstacles is crucial for optimal performance.
