How do I find the age of a DuctlessAire heat pump or air conditioner from the serial number?
Tuesday, February 22, 2022
The year of manufacture of a DuctlessAire HVAC system is at the 12th digit in their long serial number on the condenser data plate. So, be ready to count carefully to locate it. Here’s an example: 2401321290763290165004 is 2016.
Because these systems were not available in the 2000s, the single digit for the year will not be a problem until we head deeper into the 2020’s. Then you will need to check the condition of the outdoor unit, year of certified testing lab approval or industry standard, or year of construction of home or remodeling to verify which decade is correct.
For the age of another brand or manufacturer, go to our blog post How do I determine the age of my air conditioner? If you need to determine the size of the unit, go How do I find the size in tons of a DuctlessAire heat pump or air condtioner from the model number? And to figure out what all the other numbers listed on the condenser data plate mean, go to our blog post How do I understand the air conditioner or heat pump condenser label (data plate)?
