How can I tell the age of a Friedrich heat pump from the serial number?

Sunday, August 25, 2019

The first two numbers of the serial number are the year of manufacture for older Friedrich systems, as shown above for a unit built in 1984. To determine the size of your Friedrich unit, go to our blog post What size in tons is a Friedrich heat pump or air conditioner from the model number?

    Friedrich residential HVAC was acquired by ARCO in the 1980s and became Friedrich Climate Master, specializing in water source heat pumps. Then the Friedrich name was abandoned in 1987, but revived later for window units and mini-splits, which use a different serial number system.
