Results are estimates

Serial number formats are not always published, change over time and can vary between factories and product lines. Our decoders are built from the best references we can find and tested against real serials, but any result can be wrong. A manufacture date printed on the unit's label, the manufacturer's own records or your installation paperwork always take precedence over our estimate.

Lifespan figures are averages for typical conditions. Your equipment may fail well before, or run long after, the typical range.

Not professional advice

Information on this site is general and for educational purposes. It is not a substitute for an inspection by a licensed HVAC technician, plumber, electrician or home inspector. Do not rely on our results for warranty claims, insurance claims, real estate transactions or safety decisions without independent confirmation.

Water heaters, furnaces and air conditioners involve gas, high voltage, combustion and refrigerants. Turn off power before opening any access panel, and leave repairs and gas, electrical or refrigerant work to qualified professionals. If you smell gas, leave the building and call your gas utility or 911.

Advertising and affiliate links

This site may show ads and may contain affiliate links or links to contractor quote services. We may earn a commission if you make a purchase or request a quote through them, at no extra cost to you. This never affects how a serial is decoded.

Corrections

If you believe a result or any information on this site is wrong, please report it. If you represent a manufacturer and would like to share official format documentation or raise a concern, please contact us.
