Debunking a Common HVAC Maintenance Myth
One of the most persistent myths in home comfort is that you only need to change your HVAC system’s air filter once per year. This misconception is not only false but could be costing you hundreds of dollars in energy waste and potential repairs.
Let’s break down the reality of air filter maintenance:
Why Frequent Filter Changes Matter:
• Your HVAC system processes thousands of cubic feet of air daily
• Dirty filters force your system to work harder
• Energy consumption increases significantly with clogged filters
• Indoor air quality suffers with neglected maintenance
The Real Schedule You Should Follow:
1. Basic fiberglass filters: Change every 30 days
2. Pleated filters: Change every 60-90 days
3. High-end filters: Change every 6-12 months (check monthly)
For Chicagoland residents, especially in areas like Northbrook and Lincoln Park, filter changes are even more crucial due to urban pollution and seasonal allergies. During peak cooling and heating seasons, checking your filter monthly can prevent unnecessary strain on your system.
The Cost Impact:
Regular filter changes can:
• Reduce energy bills by 5-15%
• Extend equipment life
• Prevent expensive emergency repairs
• Maintain manufacturer warranty requirements
Don’t let this common misconception impact your comfort and budget. Whether you’re in Skokie, Glenview, or Highland Park, maintaining clean filters is one of the simplest ways to ensure your HVAC system runs efficiently year-round.
Remember: The small investment in regular filter changes pays significant dividends in system performance and longevity.
