Getting a HEAR rebate application returned for an invoice error is the most frustrating outcome on a completed job. The work is done, the equipment is installed, the client is happy — and you're waiting 6-12 weeks before discovering the invoice was missing something that adds another month to the clock. This guide covers what every HEAR invoice must include, what commonly gets rejected, and a checklist to review before you submit.
These fields are required across all state HEAR programs. Missing any of these is virtually guaranteed to get your invoice returned:
| Field | Requirement | Notes |
|---|---|---|
| Contractor business name | Required | Must match the name on your contractor enrollment exactly — DBA vs. legal name variations can cause mismatches |
| Contractor license number | Required | State-issued contractor license number; some states require the specific license type (HVAC, electrical, plumbing separately) |
| Client name and service address | Required | Must match the enrollment application exactly — address format differences (St. vs. Street) can cause rejections in some portals |
| Installation date | Required | Must be after the application/pre-approval date in states with pre-approval requirements; must be within the program's eligible date window |
| Equipment make and model number | Required | Include both outdoor and indoor unit model numbers for split systems; must match AHRI certificate |
| Equipment serial number | Required | Required in most states; some require serial number from both indoor and outdoor units |
| AHRI certificate number | Required | The matched system certificate from ahridirectory.org — not just the outdoor unit number. Critical for efficiency verification. |
| Itemized costs | Required | Equipment cost and labor cost itemized separately in most states; some use total installed cost. See note below on cost documentation. |
| Total invoice amount | Required | The amount the client actually paid (or will pay) for the installation |
| Contractor signature or certification | Required | Statement that work was completed in accordance with program requirements; many portals have a digital certification checkbox |
These fields are required in some state programs but not all:
| Field | Status | When Required |
|---|---|---|
| Building permit number | State-dependent | Required in states where HVAC installations require a permit (most do — check local codes). MD, IL, MA explicitly require permit number on HEAR invoice. |
| ENERGY STAR or CEE tier documentation | Equipment-dependent | Some states require a copy of the ENERGY STAR certificate or CEE tier listing in addition to the AHRI number. Can typically be printed from energystar.gov. |
| Heat pump capacity at 5°F | Cold climate states | Minnesota, Wisconsin, Michigan, New York (zones 5-6), Massachusetts, Illinois — some require rated capacity at 5°F on invoice to verify cold climate certification |
| Commissioning report or Manual J | HOMES and some HEAR states | Required for HOMES modeled pathway; some states (Georgia, Illinois) require Manual J for HEAR heat pump applications |
| Existing equipment information | Replacement projects | Some states require documentation of what was removed (make, model, fuel type) to confirm the project replaces fossil fuel equipment |
| Weatherization details | Insulation/air sealing claims | For insulation and air sealing rebates: area treated, R-value achieved, blower door test results before and after (required in some states) |
| Subcontractor information | Subcontracted work | If a subcontractor performed the installation, some states require their license number and certification on the invoice or as a separate attachment |
For heat pump HVAC systems, the AHRI certificate number is the single most important piece of equipment documentation on your invoice. Here's why:
Before you invoice, understand which payment model your state uses. This affects how you write the invoice and how you explain it to clients:
| Payment Model | States Using It | Invoice Implications |
|---|---|---|
| Rebate to client (most common) | NY, MA, MD, IL, MI, WI, NC, GA, IN, WA, CO, AZ | Invoice client your full installed cost. Program sends rebate directly to client after approval. Client pays you in full — their rebate arrives separately. |
| Point-of-sale (POS) | New Mexico (RebateBridge) | Rebate is applied at installation — client pays net price. Your invoice shows full price and rebate amount as a line-item reduction. Contractor receives rebate from program and passes savings to client. |
| Contractor-pass-through | Some programs within MA, MI | Program pays contractor; contractor issues a rebate credit to client on their invoice. Invoice shows full price and rebate credit as separate lines. |
| State | Specific Invoice Requirements |
|---|---|
| New York | NYSERDA Clean Heat portal requires equipment make/model, AHRI certificate number, serial numbers for both indoor and outdoor unit, permit number where applicable. Contractor must be enrolled in NYSERDA Clean Heat before submitting. |
| Massachusetts | Mass Save portal requires AHRI number, permit number, installer certification. BPI certification required for HPwES projects; may be checked against enrollment record. |
| Maryland | MEA portal: invoice must show itemized labor and equipment costs, permit number, AHRI number, contractor license. One of the stricter states for invoice completeness checks; also one of the fastest processors once complete. |
| Illinois | IHPA portal: Manual J required for heat pump HVAC. Invoice must show existing equipment details (fuel type, model). Permit number required. BPI or RESNET credential verification may be checked. |
| Michigan | MiHER portal: AHRI number, equipment specifications, contractor license. Some utilities require additional utility-specific documentation alongside MiHER application. Verify with both the program and your utility. |
| Wisconsin | Focus on Energy portal for most WI programs: AHRI certificate, serial numbers, permit. WI is among the fastest states to process and pay — complete invoices typically result in payment within 3-5 weeks. |
| North Carolina | NC HEAR portal (NC DEQ): contractor must be enrolled before submitting. Invoice requires model/serial numbers, AHRI certification, installed cost breakdown. NC has a verification call program where program staff may call the client to confirm installation. |
| Colorado | CO HEAR portal: equipment specifications, AHRI, serial numbers. CO has high volume and slower processing (10-16 weeks); complete invoices are especially important to avoid being moved to a secondary review queue. |
| New Mexico | RebateBridge POS system: documentation submitted at or before installation through contractor portal. Equipment must be on the approved QPL (Qualified Products List). See NM guide for RebateBridge-specific workflow. |
As HEAR programs mature, program administrators are tightening their documentation requirements. The IRA Practitioner Brief tracks state-specific invoice requirement changes and rejection pattern updates as they emerge.
