Introduction
This pack is the working copy of a replacement project. The free guides on Claude AC explain the rules; this document turns them into worksheets you fill in at each stage: the incentive check before you sign, the federal credit lines for a 2025 installation, the data a contractor needs to size the system, the efficiency minimum that applies where you live, the questions to ask every bidder, a side-by-side comparison of three quotes and the checks on installation day.
How to use it: print it (Ctrl+P or Cmd+P, then "Save as PDF", or print on paper) and keep it with your quotes. A spreadsheet version of the quote comparison is also on your access page. Start with chapter 1: it tells you which chapters apply to you.
The rules quoted are those published on October 12, 2026 by the IRS (Form 5695 instructions for 2025, the energy credits FAQ of January 2025 and the July 2025 changes known as the One Big Beautiful Bill Act), the Department of Energy (10 CFR 430.32 efficiency standards, Home Energy Rebates), the EPA (refrigerant rules) and the International Residential Code. Each chapter names its source so you can read the official text yourself.
Chapter 1: Where the money stands in 2026
The landscape changed in 2025 and most of what is still written online is out of date. Here is the position as published by the IRS and the Department of Energy.
What ended
- The Energy Efficient Home Improvement Credit (section 25C). The IRS states that the credit "will not be allowed for any property placed in service after December 31, 2025." This is the credit that paid 30% of a qualifying central AC (up to $600) or heat pump (up to $2,000). It was originally scheduled to run until 2032; the law signed on July 4, 2025 (Public Law 119-21, commonly called the One Big Beautiful Bill Act) moved the end to December 31, 2025.
- The Residential Clean Energy Credit (section 25D), which covered geothermal heat pumps (as well as solar and batteries). The IRS states that it "will not be allowed for any expenditures made after December 31, 2025", and that an expenditure is treated as made when the original installation is completed. Paying a deposit in 2025 for an installation finished in 2026 does not save it.
What still exists
- The 2025 credit itself, for 2025 installations. If qualifying equipment was placed in service in 2025, the credit belongs on your 2025 return, and the IRS confirms you can amend a return that missed it (chapters 2 and 3).
- Unused 25D credit carried forward. A 25D credit that was larger than your 2025 tax can be carried to 2026 (Form 5695 instructions). A 25C credit cannot: the IRS says unused 25C "may never be claimed".
- State Home Energy Rebates (HOMES and HEEHR), funded by the Inflation Reduction Act and run by each state energy office, where the state has launched them (chapter 4).
- Utility rebates and programs, which never depended on the federal credit (chapter 5).
- Manufacturer and distributor promotions, seasonal and stackable with most of the above.
Which chapters apply to you
| Your situation | What to do | Chapters |
|---|---|---|
| Equipment installed and running in 2025, credit already claimed | Keep the file (chapter 12); nothing else to claim federally | 12 |
| Equipment installed in 2025, credit not claimed | Claim it on your 2025 return, or amend with Form 1040-X | 2, 3 |
| Geothermal heat pump completed in 2025 with credit left over | Carry the unused 25D credit forward on your 2026 return | 2 |
| Replacing in 2026 or later | No federal credit: check state and utility money BEFORE signing, then size, compare and check | 4 to 12 |
| Installation started in 2025, finished in 2026 | Treat it as a 2026 project: no 25C or 25D credit | 4 to 12 |
| Renting your home | Utility programs may still apply; any equipment decision is the owner's | 5 |
The order that protects the money
Most incentive money in 2026 is lost by timing, not by eligibility. The order below avoids the three classic losses: a rebate refused because the application came after installation, a contractor not enrolled in the program, and equipment that misses the efficiency tier the program requires.
- Before asking for quotes: list every program you may qualify for (chapter 4 and 5 worksheets) and note which ones require pre-approval or an enrolled contractor.
- When asking for quotes: give each contractor that list and ask, in writing, whether they are enrolled and whether the proposed equipment qualifies (chapter 9).
- Before signing: get the pre-approval letters or reservation numbers that the programs require.
- After installation: submit claims within each program's deadline with the documents from chapter 12.

Frequently asked questions
Can I still get the federal tax credit for a new AC or heat pump?
Not for equipment placed in service after December 31, 2025: the IRS states that the 25C credit is not allowed after that date, and the geothermal credit (25D) ended for installations completed after it. If your equipment was installed in 2025, the pack walks you through Form 5695 and, if you missed it, the amended return (Form 1040-X). For a 2026 replacement, the money is in state Home Energy Rebates and utility programs, which the pack helps you check before signing.
How do I receive the pack?
Right after payment you are taken to your pack page, with the spreadsheet version of the quote comparison sheet. Bookmark it: the link stays valid and always shows the latest version. To keep a copy, print it or save it as a PDF from your browser (Ctrl+P or Cmd+P, then “Save as PDF”). Stripe emails you the receipt.
Is the payment secure, and is it a subscription?
You pay once on Stripe’s secure checkout page, by card, Apple Pay or Google Pay; your card details go to Stripe and never reach us. There is no subscription and nothing is charged later.
Who is behind the pack?

What is the guarantee?
The pack is guaranteed as described: if it does not open or contains an error, we fix it, and if we cannot, we refund you in full (refund policy in the terms of sale). A duplicate payment is always refunded.
