The answer to 'when to service dehumidifier' is that you should service your dehumidifier at least once per year, or more frequently if you notice decreased performance or increased noise. Regular maintenance helps ensure your dehumidifier is operating efficiently and effectively, extending its lifespan and preventing costly breakdowns.
During a dehumidifier service, you'll want to clean the air filter, coils, and other components to remove dust, debris, and buildup. This improves airflow and helps the unit work at its best. You should also check the condensate drain line to ensure it's clear and functioning properly.
