How can I tell the age of a Miller air conditioner or furnace from the serial number?
Monday, June 11, 2018
Miller is one the brands manufactured by Nordyne/Nortek, and follows their serial number format. The fourth and fifth digits of the serial number are the year of manufacture. So the serial number below on the data plate of a Miller package heat pump indicates that it was manufactured in 2010.
