How can I tell the age of a NuTone heat pump or air conditioner from the serial number?
Tuesday, November 3, 2020
The fourth and fifth digits of a NuTone serial number are the year of manufacture. So the data plate shown below indicates the condenser was manufactured in 2009. Nutone is produced by Nortek, formerly Nordyne.
But there is one exception: if the third digit is not a letter, then the third and fourth digits are the year of manufacture. This only applies to very old ones, most of which are long gone.
