The model and serial number of a Fedders air conditioner is located on the cabinet, near the barcode. The date of manufacture can be determined from the serial number as well as the production sequence.
Fedders uses five different serial number formats for its heating, venting and air conditioning units. Building Intelligence Center features a detailed description and graphic charts showing how to decode each serial number format. Fedders is a brand owned by the Airwell Group, and several HVAC brands produced by Fedders have the same serial number configurations. Those brands include Airtemp, Emerson Quiet Kool, Eubank and Koppel. Additional brands are Melcor, Rolenz, Sun, Trion and Maytag under a special license.
