About Data

This page explains how data is organized, updated, and used across our appliance savings pages.

Data Scope

Current coverage focuses on U.S. household appliance upgrade decisions, including:

  • Product/category pages
  • State rebate pages
  • State-topic rebate pages
  • Cost/savings calculator views

Data Layers Used

We maintain separate internal layers for:

  • Product records (model, category, usage assumptions, certification flags)
  • Category summaries
  • State rebate and status records
  • Federal credit mappings
  • State electricity rates
  • State emissions factors
  • Utility override references

Update Policy

We periodically refresh source data and normalize fields for page generation and calculations.
Because public datasets and official program pages change over time, historical snapshots and current program status may not always update simultaneously.

Quality Controls

Before publishing, we apply checks such as:

  • Required key fields (slug/state/model integrity)
  • URL and structural validation for generated pages
  • De-duplication and normalization where needed
  • Basic sanity checks on range/cost outputs

Known Limitations

  • Utility-specific tariffs can be more complex than state averages.
  • Program eligibility can include household income, property type, contractor requirements, and timing windows not fully represented in simplified summaries.
  • Real-world consumption may differ from baseline assumptions.

How To Use This Responsibly

Use our pages to shortlist options and estimate likely economics, then confirm:

  1. Official state/utility rebate pages
  2. Current federal guidance and filing requirements
  3. Installer/manufacturer documentation
  4. Your own utility tariff details

Feedback & Corrections

If you spot stale fields, broken links, or obvious inconsistencies, contact us and include:

  • URL
  • State/model involved
  • What appears incorrect
  • Optional source link for verification
