Common HVAC Maintenance Myths Explained
One of the most persistent myths in home comfort systems is the belief that you must change your HVAC filter every single month, no exceptions. Berwyn Western’s experienced technicians regularly encounter homeowners who’ve been needlessly spending extra money on monthly filter replacements, and it’s time to set the record straight.
The truth is that filter replacement frequency depends on several factors:
- Home occupancy levels
- Presence of pets
- Local air quality
- Filter quality and thickness
- System usage patterns
For most households, changing the filter every 2-3 months is perfectly adequate. However, homes with multiple pets or family members with allergies might benefit from more frequent changes. Conversely, a vacation home might only need changes twice per year.
High-quality pleated filters typically last longer than basic fiberglass ones. While the upfront cost is higher, they often provide better value over time and superior filtration.
Regular professional maintenance remains crucial for optimal HVAC performance, but don’t fall for the monthly filter change myth. Instead, check your filter monthly and replace it when it appears dirty or clogged. This approach saves money while ensuring your system runs efficiently.
Remember that every home is different, and your HVAC system’s needs are unique. When in doubt, Berwyn Western’s technicians can help determine the ideal filter replacement schedule for your specific situation.
The Bottom Line
While regular maintenance is essential, blindly following the monthly filter change rule isn’t necessary. Focus on monitoring your filter’s condition and understanding your home’s specific needs instead of adhering to an arbitrary schedule.
