Separating Fact from Fiction in HVAC Maintenance

At Berwyn Western, we’re committed to providing expert HVAC maintenance and repairs while also educating our customers about proper system care. Today, we’d like to address a common myth regarding HVAC filter changes that has been circulating for years.

The Myth: Change Your HVAC Filter Every Month, No Exceptions

You’ve probably heard this advice countless times: “Replace your HVAC filter every month for optimal performance.” While regular filter changes are indeed crucial for maintaining your system, the one-month rule isn’t always necessary or cost-effective.

The Truth: Filter Change Frequency Depends on Several Factors

The reality is that the ideal frequency for changing your HVAC filter can vary based on several factors:

• Filter type and quality
• Home size and occupancy
• Presence of pets
• Local air quality
• HVAC system usage

For example, a high-quality pleated filter in a small home with no pets might only need changing every 3-6 months. On the other hand, a home with multiple pets and high HVAC usage might require monthly changes.

The Berwyn Western Recommendation

Instead of blindly following the one-month rule, we suggest:

1. Checking your filter monthly
2. Replacing it when it appears dirty or clogged
3. Consulting with our experts for personalized advice based on your specific situation

By following these guidelines, you’ll ensure your HVAC system runs efficiently without unnecessarily wasting money on premature filter changes.

Remember, proper HVAC maintenance involves more than just filter changes. For comprehensive care and expert repairs, trust the professionals at Berwyn Western to keep your system running smoothly year-round.
