How can I tell the age of a Frigidaire air conditioner or furnace from the serial number?
Friday, June 22, 2018
Frigidaire is a brand manufactured by Nortek (formerly Nordyne) and the fourth and fifth digits of the serial number are the year of manufacure for most units. So the data plate for a package heat pump shown below indicates it was manufactured in 2001.
An older format uses five numbers followed by a dash, and then the next two numbers are the year of manufacture. The serial number 31674-95B, for example, was produced in 1995. 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)?
