How often should I change out my furnace filters? 

When it comes to maintaining a comfortable and healthy home, your HVAC (Heating, Ventilation, and Air Conditioning) system plays a crucial role. Among the many maintenance tasks you need to perform to keep your HVAC system running efficiently, changing your furnace filters regularly stands out as one of the most vital. Here are a few reasons for the importance of changing your furnace filters:



  • Improved Indoor Air Quality: One of the primary reasons for changing your furnace filters regularly is to maintain good indoor air quality. Furnace filters are designed to capture dust, pollen, pet dander, mold spores, and other airborne particles. Over time, these filters become clogged with pollutants, reducing their effectiveness. If filters are not changed, these contaminants can circulate throughout your home, leading to poor air quality that can exacerbate allergies and respiratory issues.


  • Energy Efficiency: A clean furnace filter allows for proper airflow in your HVAC system. When the filter is clogged, the system has to work harder to push air through, resulting in decreased energy efficiency. Your HVAC system may consume more energy, leading to higher utility bills. Regularly changing your furnace filters ensures that your system operates efficiently, saving energy and money.



  • Prolonging HVAC System Life: An HVAC system is a significant investment in your home, and you want it to last as long as possible. Neglecting to change your furnace filters can lead to excessive strain on the system's components, such as the blower motor and heat exchanger. Over time, this strain can result in costly repairs or even premature system failure. Changing filters regularly helps extend the lifespan of your HVAC system.


  • Consistent Comfort: A well-maintained HVAC system provides consistent comfort throughout your home. When filters are dirty or clogged, airflow becomes uneven, causing some rooms to be cooler or warmer than others. By changing your furnace filters on schedule, you ensure that your HVAC system distributes air evenly, maintaining a comfortable temperature in every room.


  • Cost Savings: Regularly changing your furnace filters is a cost-effective way to improve your indoor environment and reduce long-term expenses. The cost of purchasing replacement filters is far less than you could spend on repairing or replacing a damaged HVAC system. Additionally, clean filters help lower your monthly energy bills by improving energy efficiency.



Changing your furnace filters at the recommended intervals is a small but significant step in maintaining a healthy and efficient home. It is suggested to change these filters periodically in a 90-day rotation. In doing so, you can enjoy improved indoor air quality, lower energy costs, and a longer-lasting HVAC system. Don't overlook this essential maintenance task—it's an investment in your comfort, your health, and the longevity of your HVAC system. Make changing your furnace filters a priority, and you'll reap the rewards of a more comfortable and cost-effective home.
