Founder-Led. Verified. Nationwide.

The original nationwide HVAC filter company built on proof, not promises.

Our Story

For over 30 years, National Filter Service has helped facilities stay efficient by focusing on one thing: changing filters the right way. Founded as a privately owned, founder-led company, NFS grew from regional roots into the nation’s first dedicated HVAC filter replacement service—now trusted by multi-site operators from coast to coast.

Our Mission

We believe simple, verified service delivers the best results. Our approach eliminates upsells, inconsistent maintenance, and unnecessary repairs—replacing them with barcode verification, nationwide accountability, and one streamlined process for every customer.

The Difference

Where others see filter work as a side job, we built an entire company around it.

No maintenance upsells—just verified filter replacement.

National coverage—same standards, every site.

One point of contact—no chasing contractors or invoices.

Our team verifies every filter change, ensuring your HVAC systems perform efficiently year-round.
