The Truth About HVAC Air Filters
One of the most persistent myths in home comfort is that you should only change your HVAC air filter when it looks dirty. This misconception leads many Chicago-area homeowners to waste money on higher energy bills while potentially damaging their heating and cooling systems.
Let’s bust some common filter myths:
Myth #1: Clear-looking filters are still good
Reality: Even filters that appear clean can be clogged with microscopic particles that restrict airflow and force your system to work harder.
Myth #2: More expensive filters are always better
Reality: The highest-rated filters aren’t necessarily the best choice for every system. Some can actually restrict airflow too much, particularly in older HVAC units.
Myth #3: You can wait longer between changes in winter
Reality: Winter months often require more frequent filter changes due to:
• Closed windows keeping more particles inside
• Additional dust from holiday activities
• Pet dander becoming more concentrated indoors
• Fireplace use creating more particulate matter
The Real Cost of Neglecting Filter Changes
Properly maintaining your filter schedule can:
• Reduce energy costs by up to 15%
• Extend system lifespan
• Improve indoor air quality
• Prevent expensive repairs
For homeowners in Bolingbrook, Skokie, Evanston, and throughout Chicagoland, regular filter maintenance isn’t just about cleaner air—it’s about protecting your investment and maintaining optimal system efficiency.
Remember to check your filter monthly and replace it according to manufacturer recommendations, typically every 60-90 days for standard filters. Your specific replacement schedule may vary based on factors like pets, allergies, and local air quality.
