How to Decode Your Daikin Central Air Conditioner Serial Number

Every Daikin HVAC unit has a unique serial number that encodes critical information about the unit. Daikin uses a Year-Month (YYMM) format, where specific characters represent the manufacturing date, production facility, and unit sequence number.

For example, the serial number "2306A123456" can be decoded as follows: the first characters indicate the manufacturing date, while subsequent digits identify the production line and unit number. Our free decoder tool automatically parses this format and reveals the complete manufacturing history.

Daikin Central Air Conditioner Efficiency Over Time

Daikin has continuously improved efficiency to meet evolving federal standards. In 2006, the minimum was raised to SEER 13. In 2015, southern states moved to SEER 14. In 2023, new SEER2 standards took effect: 14.3 SEER2 (South), 13.4 SEER2 (North). Modern Daikin models range from 14 to 26+ SEER.

Regarding refrigerants: Daikin units before 2010 likely use R-22 (phased out since 2020 -- expensive and harmful). Units from 2010-2023 use R-410A. Newest models use R-32 or R-454B to meet EPA regulations. Knowing your refrigerant is critical -- R-22 refills cost $100-200+ per pound.
