How can I tell the age of a Ducane air conditioner from the serial number?
Sunday, July 8, 2018
Ducane has two formats. They both have 10 digits, but the one you are most likely to encounter will start with four numbers and then a letter. The third and fourth numbers are the year of manufacture, so the the condenser unit with the serial number below was manufactured in 2007.
An older format has the year of manufacture at the 7th and 8th digits of the 10-digit sequence that is all numbers. So, for example, serial number 5258470429 shown below would indicate a 2004 year of manufacture.
To determine the size in tons of your Ducane unit, see our blog post How can I tell the size in tons of a Ducane air conditioner or heat pump from the serial number? For the age of another brand or manufacturer, go to our blog post How do I determine the age of my air conditioner?
