The missing AHRI certificate is the #1 documentation gap in HEAR heat pump applications. This guide walks you through the exact lookup process, how to match indoor and outdoor units, and what to do when equipment isn't listed.
The most common HEAR application failure: A heat pump application that includes the outdoor unit model but not the AHRI certificate for the specific indoor/outdoor combination installed. Program administrators cannot verify efficiency without the combination-specific certificate — and they will return the application.
AHRI (Air-Conditioning, Heating, and Refrigeration Institute) certifies the efficiency ratings of HVAC equipment through third-party testing. An AHRI certificate is a document that shows the rated efficiency — HSPF2, SEER2, EER2 — for a specific combination of an outdoor unit (condensing unit or heat pump) paired with a specific indoor unit (air handler, fan coil, or coil).
This matters because the same outdoor unit can have dramatically different efficiency ratings depending on the indoor unit it's paired with. A Carrier 24ACC636A003 outdoor unit paired with a FX4DNF037L00 indoor unit might achieve HSPF2 9.2 — but paired with a different air handler, the same outdoor unit might only achieve HSPF2 8.1. HEAR programs require the certificate for the installed combination, not just the outdoor unit.
Mini-splits are different: For ductless mini-split systems, the indoor and outdoor units are typically rated together as a system. The AHRI certificate will list the specific outdoor unit model and the indoor head model(s) in the configuration that was tested. Multi-zone systems have combination-specific ratings — see the multi-zone section below.
The official AHRI directory is at ahridirectory.org (also accessible at ahri.org → Directory). No account required — the directory is publicly searchable. Select "Residential" from the top menu.
Select the appropriate certification program:
Use the model number from the nameplate on the installed equipment — not the ordering code or the shipping box code. These can differ. The nameplate model number is the one AHRI tracks.
The results page will show every AHRI-rated indoor/outdoor combination for the outdoor unit you searched. Scroll through to find the row that matches your installed indoor unit (air handler or coil) model number.
The indoor unit model may appear as a prefix match — AHRI sometimes lists indoor units with a shorter model code. Check the first 6-10 characters of the model number against the nameplate on the indoor unit.
On the certificate, confirm the rated values meet HEAR's efficiency threshold for the installation location:
If the certificate shows values below these thresholds, the equipment does not qualify for HEAR — do not submit the application.
Click "View Certificate" on the matching row. The certificate will open as a PDF. Save it and include it in your HEAR application package. Most states accept the PDF directly; some require the AHRI reference number (the 7-9 digit number printed on the certificate) to be entered in the application portal.

Multi-zone mini-split systems (one outdoor unit, multiple indoor heads) have AHRI ratings for specific indoor head combinations. This creates complexity for HEAR applications:
Confirm AHRI certification before ordering equipment when a HEAR application is planned. If the combination isn't in the AHRI directory, the application cannot be processed in most states — and this is discovered after installation.
HPWHs are simpler than split systems because the entire unit (compressor, tank, heat exchanger) is one piece of equipment. The AHRI certificate for a HPWH shows the Uniform Energy Factor (UEF) — HEAR requires UEF ≥ 2.0 for a tank capacity of 40+ gallons.
At ahridirectory.org, search under "Water Heaters" → "Heat Pump Water Heater." Enter the model number from the nameplate on the installed unit. The certificate will show UEF, storage capacity, and first-hour rating. Verify UEF ≥ 2.0 and tank capacity ≥ 40 gallons before submitting.
| HPWH Brand | AHRI-Qualified Models (2026) | UEF Range | Capacity Options |
|---|---|---|---|
| Rheem ProTerra | PROPH50 T2 RH350 Series (50-gal), PROPH65 (65-gal), PROPH80 (80-gal) | 3.75–4.0 UEF | 50, 65, 80 gal |

| Mistake | What Happens | Fix |
|---|---|---|
| Submitting the outdoor unit spec sheet instead of the AHRI certificate | Application returned | A spec sheet shows maximum possible efficiency. The AHRI certificate shows rated efficiency for the specific installed combination. Reviewers know the difference. |
| Using the ordering code instead of the nameplate model number | Certificate won't match | Ordering codes sometimes have suffix characters not in the AHRI listing. Use the model number printed on the physical nameplate of the installed equipment. |
| Providing only the outdoor unit AHRI certificate for a ducted heat pump | Application returned | For split systems, the certificate must show the indoor unit in the combination. A standalone outdoor unit listing doesn't show combined efficiency. |
| Not verifying efficiency values before installation | Equipment may not qualify | Pull the AHRI certificate before installation. If the efficiency doesn't meet the threshold, the customer's $8,000 rebate expectation cannot be met — a very difficult conversation after installation. |
| Using a screenshot of the AHRI directory instead of the PDF certificate | May be rejected | Some programs require the official AHRI certificate PDF, not a screenshot. Always download the PDF from the "View Certificate" button. |
| Assuming ENERGY STAR certification = AHRI certificate | Missing documentation | ENERGY STAR certification shows a product met ENERGY STAR thresholds. The AHRI certificate shows the actual rated values for the specific installed combination. Most states require the AHRI certificate regardless of ENERGY STAR status. |
An AHRI certificate documents the efficiency rating — HSPF2, SEER2, EER2 — for a specific combination of HVAC equipment. HEAR requires it because equipment efficiency varies by indoor/outdoor combination, and program administrators need to verify the installed system (not just the outdoor unit) meets the efficiency threshold for the rebate.
Go to ahridirectory.org. Select Residential → Unitary Equipment. Enter the outdoor unit model number from the nameplate. Find the row in the results that matches your indoor unit model number. Click "View Certificate" and download the PDF. If the combination isn't listed, contact the manufacturer's contractor support line.
Yes. Mini-split systems are rated as a system (outdoor unit + specific indoor head), and the AHRI certificate for the specific system configuration is required. For multi-zone systems, you need the certificate for the exact combination of indoor heads installed, not just the outdoor unit.
First try searching by indoor unit model number, not just outdoor. Then contact the manufacturer's contractor support — sometimes combinations are listed under a parent certificate or with slightly different model suffixes. If the combination genuinely isn't rated, it cannot qualify for HEAR in most states. This is a critical check to do before installation.
Generally no. ENERGY STAR certification confirms a product met ENERGY STAR thresholds — but it doesn't show the efficiency values for the specific installed combination. Most state HEAR programs require the AHRI certificate, though some accept ENERGY STAR as supplemental documentation. When in doubt, submit both.
AHRI certificates are issued annually. Equipment that was AHRI-certified in a prior year should still be valid for HEAR purposes if the efficiency standard hasn't changed. However, if a manufacturer updates their AHRI listing (e.g., due to a product revision), the new certificate supersedes the old. Always use the most current AHRI certificate for the installed model.
