AHRI Matchup Finder
Find the listed equipment combination, compare certified ratings and open the official AHRI record. Then get the literature you need for the job.
Start with a model or AHRI number
Search an outdoor unit, indoor unit, coil or furnace. Each result keeps the combination and ratings together, including the model patterns published by AHRI.
Coverage notes: Gibson combinations, commercial suffixes and Daikin VRV
- Gibson: references were found for WSA4BD5M1SN24K, WSA4BD5M1SN30K, WSA4BD5M1SN36K and C75BHMX30C-B, but a condenser/coil combination linking those models has not been confirmed in this collection. Check the complete pair shown on the AHRI record.
- Commercial / unitary: the added Ruud leads require full model-suffix verification. An Active record does not confirm an unverified suffix.
- Daikin VRV: configurations remain unresolved in this collection. Use manufacturer selection assistance and the official AHRI Directory.
Enter a model or AHRI number to begin.
Check the complete combination
Match every listed component
Use the outdoor, indoor and furnace models together. Preserve asterisks, model options and accessory qualifications. A blank component field does not select the controls, blower or other installation accessories.
Read the matching evidence
An exact model, a published wildcard and an AHRI-normalized lookup are different references. A series search is a starting point. Suffix questions and generic multi-zone indoor configurations require confirmation.
Open the current AHRI record
Verify the complete configuration and current listing before quoting. SEER and SEER2, EER and EER2, and HSPF and HSPF2 remain separate. A rating alone does not establish rebate eligibility.
