Steps
For one-off lookups, use the free public search at ahridirectory.org/certificate by AHRI Certified Reference Number or full/partial Model Number.
Pull the AHRI Certificate or Reference Number from the equipment nameplate or an existing directory listing to verify certified SEER2/EER2/HSPF2 and capacity ratings.
For programmatic or bulk access, apply to the AHRI Data Subscription Program (license agreement required) rather than scraping the public site.
Within that subscription, elect the add-on API Service — the Unitary API requires a Unitary/Unitary+Cooling package purchase and the Heating API requires the Heating package; the API is not sold standalone.
Budget against AHRI's published Packages and Fees schedule (subscription plus add-on API fee) before scoping a product feature around this data.
Known gotchas
The public website is a manual search tool, not a free/open REST API — there is no anonymous bulk-query endpoint.
Programmatic access requires first purchasing the underlying data package (Unitary or Heating); the API service is an add-on, not standalone.
Certified ratings can be modified or delisted by manufacturers — re-verify against the live directory for compliance-sensitive uses like rebate eligibility rather than caching indefinitely.
