Equipment & Performance

Air Filters questions
Answers to questions that come up often with this service.
It depends on the filter type, the home, and pets, but a common range is every one to three months. A thicker media filter may last longer.
Not always. A filter that is too restrictive for the system can reduce airflow and cause problems. The right rating balances filtration with the system's airflow capacity.
