What maintenance task should be performed regularly on HVAC filters?

Regular maintenance of HVAC filters is essential to ensure the system operates efficiently and effectively. Changing or cleaning the filters on a routine basis helps prevent dust, dirt, and other particles from accumulating, which can obstruct airflow and reduce the efficiency of the system.

When filters are maintained regularly, it not only improves indoor air quality but also extends the lifespan of the HVAC system by reducing strain caused by restricted airflow. Regular intervals for changing or cleaning filters can vary based on factors such as the type of filter, the HVAC system, and environmental conditions, but generally, it is advisable to perform this task every one to three months.

In contrast, replacing filters only once a year may neglect the buildup of dust and debris that can occur throughout the year. Cleaning filters only when clogged does not take proactive measures to maintain optimal airflow and efficiency. Changing filters every six months could still leave the system vulnerable to performance issues during the off months, depending on usage and environmental factors. Therefore, the most effective approach is to establish a regular schedule for changing or cleaning filters to ensure the HVAC system operates at peak performance.
