How Often Should You Change Your Air Filters?

As we go about our days with our heating and cooling systems quietly doing their job, it’s easy to forget about the air filters silently working to keep our indoor air clean. But neglecting to change these filters regularly can lead to a buildup of dust, hair, dander, and even mold spores over time. This buildup not only hampers the efficiency of our HVAC systems but also degrades the quality of the air we breathe indoors. Such a decline in air quality can result in symptoms like headaches, fatigue, and sinus congestion for you and your family.

So, how often should you be changing your air filters? The general recommendation is every three months, but this can vary depending on factors such as your location, the age of your HVAC unit, and the size of your home. A quick monthly check by holding the filter up to the light can reveal if it’s time for a change – if light doesn’t pass through, it’s time to replace the filter.

If you own a ductless AC system, the frequency of filter cleaning is even more crucial. It’s usually recommended to give these filters a thorough clean every two to four weeks to ensure optimal efficiency. Additionally, an annual replacement of the air filter is advised to maintain peak performance.

Similarly, furnace filters should generally be replaced every 90 days,  but households with pets or allergy sufferers may need to do so more frequently. The type of filter also plays a role in determining the replacement frequency. If unsure, consulting one of our professional HVAC technician can provide clarity.

For heat pump owners, experts suggest replacing the filter at least twice a year. Signs that your heat pump’s filter needs changing include decreased efficiency in heating or cooling your home, indicating a clogged filter obstructing airflow.

Ultimately, being proactive about changing your HVAC system’s filters not only ensures its smooth operation, but also contributes to a healthier indoor environment for you and your loved ones. So, make it a habit to stay on top of filter changes – your HVAC system and your family will thank you for it.
