How often should I replace my AC air filter?

It is generally recommended to replace your AC air filter every 1 to 3 months, depending on usage, the type of filter, and household conditions such as pets or allergies. Checking the filter monthly is a good practice to determine when it needs changing.

What are the signs that my AC air filter needs to be replaced?

Signs include reduced airflow, increased energy bills, visible dirt or dust buildup on the filter, poor indoor air quality, and frequent cycling of the AC system. If you notice any of these issues, it may be time for a replacement.

Can I clean my AC air filter instead of replacing it?

Some filters, like washable or reusable filters, can be cleaned and reused. However, disposable filters should be replaced rather than cleaned, as cleaning them may not remove all contaminants and can damage the filter.
