What is the recommended frequency for replacing HVAC air filters?

Replacing HVAC air filters regularly is essential for maintaining optimal air quality and system efficiency. The recommended frequency of every 1 to 3 months is based on several factors that influence air filter performance and longevity, including the type of filter, the environment in which it's used, and how often the HVAC system operates.

Air filters capture dust, allergens, and other particles from the air before it circulates in a building. Over time, these filters can become clogged, leading to reduced airflow, increased energy consumption, and potential damage to the HVAC system. By changing filters every 1 to 3 months, homeowners can ensure that their systems run efficiently, maintain good indoor air quality, and prolong the life span of the equipment.

Certain conditions, such as having pets, living in a dusty environment, or running the HVAC system frequently, may necessitate more frequent changes within that 1 to 3-month window. It's important to regularly check the condition of the filter and replace it as necessary to ensure that the heating and cooling system operates effectively and efficiently.
