Why Age Matters For DUCANE Repair vs Replace
Knowing the true manufacture date of a DUCANE unit changes the conversation with the customer. A unit past its expected service life rarely benefits from a high-cost compressor or coil repair, and warranty windows hinge on the exact year built — not the year installed.
- Warranty validation: Many DUCANE parts warranties run 5 or 10 years from the manufacture date, not the install date.
- Replacement timing: Compare decoded age vs typical DUCANE service life to recommend repair vs replace with confidence.
- Refrigerant context: Older DUCANE units may still be R-22. The decoder plus the matching profile shows refrigerant so quotes are accurate.

DUCANE encodes the manufacture date in the serial. Capacity, refrigerant, and tonnage come from the model. Using both gives a high-confidence age and spec read for repair vs replace decisions.
