Maintenance · Article 10 of 25
Quick answer: Check the filter monthly, then follow its instructions and your equipment requirements for cleaning or replacement.
Understanding the issue
Check the filter monthly, then follow its instructions and your equipment requirements for cleaning or replacement. There is no single replacement interval that fits every home. Dust, pets, usage, and filter design affect how quickly it loads.
What homeowners can do
Use the correct dimensions and install the filter in its indicated airflow direction. With the system off, replace a disposable filter when it is dirty or due under its instructions. Wash only filters specifically designed for washing, and follow their drying directions.
How Francisco’s Cooling & Heating can help
Francisco’s Cooling & Heating can help you identify the filter location and appropriate type. If the filter becomes dirty unusually quickly or does not fit properly, mention it at your appointment. Regular checking is more useful than assuming an advertised lifespan will match your home.
