Dirty Air Filter

Your delonghi pinguino air conditioner may not be cooling properly because of a dirty air filter. Air filters prevent dirt, dust, and other particles from entering the ac system – which can cause the cooling process to slow down or stop entirely.

That’s why it’s important to clean the filter regularly to maintain proper airflow and efficient cooling. Follow these simple steps to clean the filter: turn off the unit, remove the filter, gently clean it with a soft brush or vacuum, and reinstall the filter.

To ensure regular maintenance, clean the filter every two weeks, or more frequently if you use the ac frequently or have pets. This simple maintenance task will help your delonghi pinguino cool your home more efficiently and help prolong the lifespan of your air conditioner.

Clogged Exhaust Hose

A clogged exhaust hose is one of the most common reasons why your delonghi pinguino may not be cooling properly. The exhaust hose is responsible for releasing hot air from the unit to the outside. If it becomes clogged with dirt, dust, or debris, the hot air cannot escape which will cause the unit to struggle to cool effectively.

To clean the exhaust hose, start by unplugging the unit and removing the hose. Use a vacuum cleaner or a brush to remove any blockages or debris. Ensure that the hose is straight and free from twists and kinks before reconnecting and attaching it to the unit and the window.

Regular maintenance is key to avoiding blockages in the exhaust hose. We recommend cleaning it at least once every three months to ensure optimal performance.

Damaged Air Intake Grille

If you notice your delonghi pinguino is not cooling as it should, check the air intake grille. A damaged grille can lead to reduced cooling. Inspect and replace a damaged grille with a step-by-step guide. Regular maintenance is key to keeping the grille in good shape.
