The Truth About Air Filters and Your HVAC System

One of the most persistent myths in home comfort is that you should change your HVAC filter every 30 days without exception. While regular maintenance is crucial, this one-size-fits-all approach isn’t always necessary and could be costing you extra money.

Let’s break down the facts:

Filter Change Frequency Depends On Multiple Factors:

• Household size and activity level
• Number of pets in the home
• Local air quality and construction in your area
• Type of filter being used

High-quality pleated filters can often last up to 90 days in homes with average use. However, homes with multiple pets or in areas with poor air quality might need more frequent changes.

Signs You Actually Need a Filter Change:

• Visible dirt and debris on the filter surface
• Increased energy bills
• Slower airflow from vents
• More dust settling on furniture

Another common misconception is that the more expensive the filter, the better it is for your system. In reality, using a filter that’s too dense can restrict airflow and make your system work harder, potentially leading to premature wear and tear.

The key is finding the right balance between filtration and airflow for your specific system and household needs. When in doubt, consulting with a professional HVAC technician can help you determine the optimal filter type and replacement schedule for your home’s unique situation.

Remember, proper filter maintenance is just one part of keeping your HVAC system running efficiently. Regular professional maintenance checks ensure your entire system operates at peak performance throughout the year.
