The Monthly Filter Change Myth

At Relentless Cooling & Heating, we often hear customers say they religiously change their HVAC filters every month because that’s what they’ve always been told to do. While regular maintenance is crucial, this one-size-fits-all approach isn’t always necessary or cost-effective.

The Truth About Filter Changes

Filter replacement frequency actually depends on several factors:

• Home size and occupancy
• Number of pets
• Local air quality
• Filter quality and thickness
• System usage patterns

For example, a single person living in a clean environment with no pets might only need to change their filter every 6 months, while a family with multiple pets and allergies might benefit from bi-monthly changes.

How to Know When It’s Time

Instead of blindly following a calendar-based schedule, we recommend:

1. Visually inspecting your filter every 60 days
2. Holding it up to a light source – if you can’t see light through it, it’s time to change
3. Setting reminders for regular inspections rather than automatic replacements

By understanding your specific needs, you can maintain optimal system performance while avoiding unnecessary expenses. At Relentless Cooling & Heating, we’re committed to providing honest, practical advice that helps our customers make informed decisions about their HVAC maintenance.

Remember: An efficient system doesn’t always require the most frequent maintenance – it requires the right maintenance at the right time.
