How can I tell the age of a Guardian air conditioner from the serial number?
Tuesday, July 10, 2018
Guardian heat pumps and air conditioners are manufactured by Unitary Products Group, and the first two numbers that appear in the serial number (located at the 2nd and 4th position in the alphanumeric sequence) indicate the year of manufacture. So the serial number on the Guardian data plate shown below translates to a 2011 year of manufacture.
