To ensure peak performance, clean or replace the air filter in your Firstco UC-HW Series Fan Coil Unit every 30 days. However, if your environment has heavy dust or other severe conditions, more frequent may be necessary. A clean air filter is critical for maintaining efficient airflow and optimal heat transfer within the unit. Always use a replacement filter of the same type as the original to guarantee proper filtration and airflow. Regular filter maintenance is key to maximizing the efficiency and lifespan of your Firstco fan coil unit.
