About this tool
This tool estimates a unit's manufacture date using publicly documented serial-number date-coding conventions for each brand. These conventions have changed over the decades and can vary by product line, so treat results as an estimate, not an official record.
For an authoritative check, look up the model and serial number on the AHRI Certified Reference Directory, or contact the manufacturer / installing dealer directly with your model and serial number.
