How do I determine the age of a WeatherKing air conditoner, heat pump, or furnace from the serial number?
Monday, December 16, 2019
We know of two serial number formats for WeatherKing. For the first: look for the second cluster of digits in the serial number, and the 3rd and 4th number after the single letter is the year of manufacture. The month and year of production also stated clearly in the upper right of the data plate.
Another variation: look for a single letter in the middle of the serial number, and the 3rd and 4th digits after it are the year of manufacture.
