How often should HVAC air filters be changed?

HVAC air filters should ideally be changed every 1 to 3 months. Regularly changing air filters is essential for maintaining optimal airflow and efficiency in HVAC systems. When filters become clogged, they restrict airflow, which can strain the system and increase energy consumption. This can lead to wear and tear on the equipment, reduced indoor air quality, and possibly higher utility bills.

Different factors such as the type of filter, the environment, and usage patterns can influence how frequently filters need to be replaced. For instance, homes with pets or allergens might require more frequent changes to maintain clean air. Hence, the 1 to 3 month timeframe is a practical guideline for most residential and light commercial applications, ensuring that the HVAC system operates efficiently and effectively.
