Terms of use

Last updated: October 22, 2026

By using hvacdecode.com (the "site") you agree to these terms. If you do not agree, please do not use the site.

Information only, no professional advice

The site estimates the manufacture date of equipment from published serial number formats. Manufacturers change their formats, some codes repeat over time, and the date shown is the factory date, not the installation date. Results are provided for general information only and may be wrong.

Nothing on the site is professional plumbing, HVAC, electrical, safety or warranty advice. Always confirm the date on the equipment label or with the manufacturer, and have a licensed professional inspect, repair or replace gas, electric, refrigerant or water heating equipment. Warranty coverage depends on the manufacturer's own terms.

No warranty and limitation of liability

The site is provided "as is" and "as available", without any warranty of any kind. To the fullest extent permitted by law, HVACDecode is not liable for any loss or damage arising from your use of the site or from decisions made based on its results.

Affiliate links and third-party sites

Some links point to Amazon or other third-party sites and may earn us a commission (see ouraffiliate disclosure). We do not control those sites and are not responsible for their content, products, prices or policies.

Trademarks

Brand names such as Rheem, Carrier, A.O. Smith, Bradford White, Trane or Goodman belong to their respective owners and are used only to identify their products. HVACDecode is independent and not affiliated with or endorsed by any manufacturer.

Acceptable use

Do not attempt to disrupt the site, copy it in bulk with automated tools, or reuse its content commercially without permission.
