What the reference number is for
- Permits. Most jurisdictions ask for the certified rating of the installed combination, not the condenser alone. The reference number is the lookup key.
- Rebates. Utility programs verify efficiency against AHRI’s record for the pair. Where the rebate money is now.
- The 25C tax credit. The credit is tied to the certified rating of the system as installed. Is there still a credit in 2026?
