This feature is only used by AHRI Certification Program participants (manufacturers) and authorized users of the for-a-fee AHRI Data Subscription program. Only users who have been issued AHRI account credentials are permitted to log into the AHRI Directory. AHRI accounts are not issued to users seeking to perform product searches or download certificates as this can be done on the public site without logging in. Additionally, an AHRI Account does not give public users access to any additional features or data fields beyond what is available on the public Directory site.
