The Truth About HVAC Air Filters
One of the most persistent myths in the HVAC industry concerns air filters and their maintenance. At Riley Heating & Cooling, we frequently encounter homeowners who have been misled by common misconceptions about their filtration systems and proper maintenance schedules.
Let’s debunk some of the most widespread filter myths:
Myth #1: The more expensive the filter, the better it is for your system
Actually, using a filter that’s too dense or high-grade can restrict airflow and force your system to work harder. This can lead to increased energy costs and potential system damage. The key is finding the right balance between filtration and airflow.
Myth #2: You only need to change filters once a year
This is absolutely false! The frequency of filter changes depends on several factors:
• Pet ownership
• Number of occupants
• Local air quality
• Seasonal changes
• Type of filter used
Most Oak Park homes require filter changes every 2-3 months, with some households needing monthly changes during peak usage seasons.
Myth #3: Any filter will work as long as it fits
Using the wrong type of filter can severely impact your system’s performance. Your HVAC system is designed to work with filters of specific MERV ratings (Minimum Efficiency Reporting Value). Using the incorrect rating can lead to:
• Reduced efficiency
• Higher energy bills
• Potential system damage
• Poor indoor air quality
Remember, proper filter maintenance is crucial for system longevity and efficiency. When in doubt, consult with HVAC professionals who can recommend the right filter for your specific system and household needs.
By understanding these facts about HVAC filtration, Oak Park homeowners can make better decisions about their system maintenance and potentially save money on energy costs while maintaining optimal indoor air quality.
