By accessing or using Serial-Decoder.com ("the Site"), you agree to these Terms of Use. If you do not agree, please do not use the Site.

2. Nature of the Service

The Site provides a free, informational tool that estimates the manufacture date and age of HVAC equipment and home appliances based on publicly documented manufacturer serial number formats. Results are estimates only. Manufacturers change formats without notice, and some serial numbers are ambiguous across date cycles. Always verify critical information (such as warranty eligibility) directly with the manufacturer.

The Site's content, design, and decoding tools are the property of Serial-Decoder.com. Brand names mentioned on the Site (Carrier, Trane, Lennox, Whirlpool, GE, and others) are trademarks of their respective owners. Serial-Decoder.com is not affiliated with, endorsed by, or sponsored by any equipment manufacturer.

5. Affiliate & Advertising Disclosure

The Site may display advertising and may include links to third-party retailers or service providers for which we may earn a commission. These relationships do not affect decode results.

6. Limitation of Liability

The Site is provided "as is" without warranties of any kind. To the maximum extent permitted by law, Serial-Decoder.com shall not be liable for any damages arising from use of the Site or reliance on its estimates.
