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

Wednesday, June 13, 2018

The RADCO logo appears prominently on the data plate of some older HVAC units. We have noticed them only on systems manufactured by Carrier/Bryant/Payne. But RADCO is actually a product testing and certification lab, like UL and ARI. If the manufacturer’s brand medallion is missing on the equipment, the large RADCO emblem on the data plate is sometimes mistaken for the name of the manufacturer. 

    The Carrier family of brands uses the second two numbers of the serial number for the year of manufacture, and the one shown below indicates the unit was manufactured in 2001. We are not sure if RADCO logo was also printed on other manufacturer’s data plates, so can’t verify that it will always be a Carrier product. By the way, RADCO is an acronym for Resources, Applications, Designs and Controls, Inc., and they have had a different, updated logo since 2012.
