How can I tell the age of an LG heat pump or air conditioner from the serial number?

Thursday, April 23, 2020

The first digit in the serial number on an LG data plate is the year of manufacture, but it does not give you the decade. So, for example, 705KWPZ64912 could be 2007 or 2017. Look at the condition of the unit for an indication of the decade. The serial number might also be on a separate sticker below the data plate and include the month and year of manufacture at the end, such as "05 2017."

    For the age of another brand or manufacturer, go to our blog post How do I determine the age of my air conditioner?
