How can I tell the age of a Rheem air conditioner or furnace from the serial number?
Saturday, June 23, 2018
Find the letter in the middle or beginning of the serial number. The first two numbers after it are the week of manufacture, and the third and fourth numbers after the letter are the year of manufacture. The month and year of manufacture is also indicated at the upper right of the data plate. So the “G0994” in the serial number below means it was manufactured in the 9th week of 1994, and the “MFD. 03/94” confirms it. There’s also the option of going to the Rheem website’s serial number lookup page at https://www.rheem.com/how-old-is-my-air-conditioner/. And for the age of another brand or manufacturer, go to our blog post How do I determine the age of my air conditioner?
