Regularly checking the filter status and airflow is crucial for maintaining optimal performance in HVAC systems. Filters play a key role in trapping dust, dirt, and other airborne particles, preventing them from entering the system and affecting its efficiency. Clogged or dirty filters can restrict airflow, leading to decreased system performance, higher energy consumption, and potential damage to the system components. Ensuring that filters are clean and unobstructed allows the HVAC system to operate efficiently, providing effective heating and cooling while also prolonging the life of the equipment.

Airflow, which is determined by various factors including the condition of the filters, should also be monitored. Adequate airflow ensures that conditioned air is effectively distributed throughout the space. If airflow is insufficient, it can lead to temperature imbalances, increased wear on the system, and higher utility bills. Regular checks help identify any blockages or issues early on, allowing for timely maintenance before these problems escalate.
