How can I tell the age of my Allied Air heat pump or air conditioner from the serial number?
Monday, May 18, 2020
We know of two versions of the serial number age coding system for Allied Air. The first one uses the third and fourth number for the year of manufacture, so that 1408C12153 would be 2008. The second system puts the year in the 7th and 8th number (3rd and 4th from the end) of the serial number, so 5123610221 was produced in 2002. And here’s an example from 2018.
To determine the size of a Allied Air system in tons, see our blog post What size in tons is my Allied Air heat pump or air conditioner? For the age of another brand or manufacturer, go to our blog post How do I determine the age of my air conditioner?
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)?
