How We Check Rebates

Our process for sourcing, reviewing, and maintaining verified home energy rebate data across 49 US states.

We source from official program pages only

All rebate data comes directly from official utility program pages, state energy agency websites, IRS publications, and primary source documents — confirmed with HTTP 200 responses, program PDFs, or official portal lookups. We do not use aggregator sites, press releases, or secondhand summaries as primary data. Every source is linked and dated on the relevant page.

We show when each source was last checked

Every state rebate page shows a 'last checked' date indicating when we last verified the source data. Utility rebate pages are reviewed when programs announce changes. Federal program pages are reviewed monthly. State program pages are reviewed at least quarterly. Pages showing outdated data display a prominent notice to verify directly with the utility.

We use confidence scores, not guarantees

Confidence scores indicate how complete and verifiable a rebate estimate is based on the information available. A high confidence score means we have verified the rebate tiers from an official source and the key inputs are confirmed. A medium or low score means key inputs are missing — the estimate may still be useful but should be verified before acting on it.

We never say 'you qualify' — we say 'you may qualify'

Our calculators estimate rebate ranges based on what you tell us. We cannot verify equipment eligibility, utility participation, or actual application approval. We flag missing inputs that are required for actual eligibility and tell you what questions to ask.
