Should You Change Your Air Filter Monthly in Winter?

Keep your HVAC system’s filter clean to avoid restricted airflow, but you may not know if you need to replace it every month during the winter.

It is recommended that you check your filter monthly and replace it if there is any accumulation of debris, or at least every three months.

As a result of frequent filter changes, there are a number of benefits, such as longer component lifespans, lower utility bills, better air quality, and fewer breakdowns. When you keep a clean filter in your HVAC system, it can helps prevent any unnecessary strain on the various system components. The added strain can cause your equipment to fail prematurely as it ages, so preventing it can help you delay the need to purchase new equipment. A third costly consequence of ignoring filter changes is that the HVAC system has to work harder to compensate for the reduced airflow. Consequently, the equipment’s efficiency declines, and its energy consumption and your utility bills. Your monthly operating costs can be reduced by five to fifteen percent if you maintain a clean filter. The importance of routine filter inspections and changes is even greater if you have an air cleaner unit on your HVAC system. As these filters have higher minimum efficiency reporting values, they can quickly restrict airflow if they become clogged. If your air filter isn’t changed often enough and is coated with debris, these particles can get into your HVAC system and collect on sensitive components, causing equipment failures. By changing the filter regularly throughout the winter, you can avoid inconvenience, discomfort, and preventable repairs.
