Why is using National Filter Service better than hiring local companies to do the same work?
• One source nationwide for all your HVAC filter and preventative maintenance needs. • Consistency of service and quality control. • Consistency of filter product quality. • NFS is the only company of its kind: nationwide, not merely local or regional, staffed with our own uniformed technicians, not sub-contractors. • Maintaining employees instead of sub-contractors ensures a consistent high level of performance, materials and reliability. • The same price for every location–conveniently batched, single-vendor invoicing to simplify your accounting. • Experience–NFS has been in business since 1991. • Over 15,000 locations being serviced monthly. • Trusted by some of the biggest names in retail and restaurants.
