How can I tell the age of a Westinghouse heat pump or air conditioner from the serial number?
Saturday, February 23, 2019
Westinghouse was manufactured by Nortek (formerly Nordyne) and uses their serial number system. The fourth and fifth characters in the serial number are the year of manufacture on most units we have found. So the serial numbers shown below on the data plate of a Westinghouse air handler and condenser indicates that both were manufactured in 2008. But some data plates have the year of manufacture at the third and fourth character location.
