CEE Advanced Tier qualifying models (2026)

Always verify the specific model number against ENERGY STAR\'s qualified product database (energystar.gov/productfinder) before installation. Manufacturers update product lines annually — what qualifies in 2026 may be different in 2027.

North vs South region — the cold climate distinction

For homes in the EPA-defined "North" region (typically above the 4,500 Heating Degree Day line — most of the northern US), the heat pump must additionally have ENERGY STAR Cold Climate certification. This certification verifies the heat pump:

Southern region installations (Florida, Texas, Arizona, etc.) need only meet CEE Advanced Tier — Cold Climate certification is not required. However, many manufacturers ship cold-climate-certified models nationally; check the spec sheet.

How to claim the credit on your tax return

  1. Save the manufacturer's certification statement (heat pump model qualifies for Section 25C)
  2. Save all installer invoices showing labor + materials cost
  3. File IRS Form 5695 with your federal return (Energy Efficient Home Improvement Credit)
  4. Enter the heat pump cost on Part II Section A — check "Heat pump" box, enter cost (cap $2,000)
  5. If also claiming windows/insulation: complete other Part II sections
  6. Result flows to Schedule 3 line 5a, then 1040 line 20
  7. Keep paperwork for 7 years in case of audit (manufacturer cert + invoices)
