In terms of air conditioning maintenance, how often should filters ideally be changed?

Changing air conditioning filters monthly is recommended to ensure optimal performance and efficiency of the HVAC system. Regular maintenance of filters is crucial because clean filters allow for better airflow and more efficient operation, leading to improved indoor air quality and reduced energy costs. When filters are dirty, they can restrict airflow, making the system work harder and potentially causing premature wear or damage. Additionally, frequently replacing filters helps to minimize allergens and dust in the home, promoting a healthier environment.

While some systems or situations may allow for longer intervals, such as every season or every two years, these generally apply to specific circumstances or types of filters. However, a monthly change is a widely accepted best practice for standard household air conditioning systems to keep them operating effectively.
