The Truth About HVAC Air Filter Changes: More Often Isnt Always Better

Common AC Maintenance Myths Explained

One of the most persistent myths in home comfort maintenance is that changing your HVAC air filter every single month is absolutely necessary for optimal performance. At Jackson & Foster, we regularly encounter homeowners who’ve been needlessly spending extra money on filters due to this misconception.

Let’s break down the reality:

Facts About Air Filter Changes:

• Basic fiberglass filters: Change every 30-60 days
• Pleated filters: Every 60-90 days
• High-end filters: Can last up to 6 months

Several factors influence how often you should change your filter:

• Pets in the home
• Number of occupants
• Local air quality
• Usage patterns

Over-changing filters not only wastes money but can also create unnecessary waste. The best approach is to visually inspect your filter monthly and change it when it appears dirty, rather than adhering to a strict calendar schedule.

For San Diego area residents, our unique coastal climate actually means filters often last longer than in other regions, thanks to our generally clean air quality. However, during Santa Ana winds or fire season, more frequent changes might be necessary.

Remember, your HVAC system is designed to work efficiently with slightly used filters. A pristine filter isn’t always better for your system’s performance or your indoor air quality.
