How can I tell the age of a Panasonic heat pump or air conditioner from the serial number?
Thursday, April 23, 2020
The age is not encoded in the serial number for Panasonic products. It is usually listed on the data plate as “DATE NO." So the data plate shown below indicates the unit was built in 2005.
But it may also be shown on the data plate as “PRODUCTION YEAR,” and the first four digits of the six digit number are the year of manufacture. So 201206 would be 2012.
For the age of another brand or manufacturer, go to our blog post How do I determine the age of my air conditioner? To determine the size of a Pansonic system, see our post What size in tons is a Panasonic air conditioner or heat pump from model number?
