How Often To Replace Your Home Air Filters
Replacing your air filter regularly is one of the simplest and most important ways to keep your HVAC system running efficiently and your indoor air clean. For most homes, filters should be replaced every 1 to 3 months. However, the exact timing depends on several factors. You may need to replace filters more often if:
- You have pets that shed hair and dander
- Family members have allergies or respiratory issues
- Your home has higher dust levels or outdoor pollutants
- Your HVAC system runs frequently, especially during hot Texas summers
Some high-efficiency or media filters can last longer, often up to 6 months, but they should still be checked regularly to ensure proper airflow. Signs your filter needs replacing include:
- Reduced airflow from vents
- Increased dust buildup in your home
- Your system running longer than usual
In the Texas Hill Country, where dust and allergens are common, staying on top of filter changes helps maintain better air quality and system performance. 72 Degrees Texas can recommend the right filter type and replacement schedule for homeowners in Fredericksburg, Kerrville, and surrounding areas to keep systems running efficiently year-round.
