Maintaining efficient airflow in an AC system is crucial for optimal performance and energy efficiency. Regular filter changes play a vital role in this process. Air filters trap dust, dirt, and other particulates that can obstruct airflow. When filters are clogged, they restrict the amount of air that can flow through the system, leading to reduced efficiency, increased energy consumption, and potential damage to the unit. By replacing or cleaning filters regularly, airflow is maintained at optimal levels, allowing the system to operate more effectively and reducing the likelihood of system strain or failure.

Other factors like proper insulation, while important for overall efficiency and loss prevention, do not directly impact the airflow within the AC system itself. Minimizing refrigerant could imply an undercharged system, which also does not support efficient airflow. Increasing compressor speed can have effects on performance, but it does not address the fundamental need for unobstructed airflow, which is best achieved through regular filter maintenance.
