How can I tell the age of a Payne air conditioner or heat pump from the serial number?
Friday, April 19, 2019
The third and fourth numbers in the serial number on the data plate are the year of manufacture for Payne, so the one shown below is from 2008. This format has been used from the mid-1980s to the present.
The more recent Payne units we have seen don’t require you to know which numbers are the year of manufacture. Some of them, like the one below, state it clearly at the bottom of the data plate.
To determine the size of a Payne system in tons, see our blog post How many tons is my Payne air conditioner or heat pump? For the age of another brand or manufacturer, go to our blog post How do I determine the age of my air conditioner?
