How can I tell the age of a CAC/BDP or BDP air conditioner or furnace from the serial number?

Saturday, June 23, 2018

These systems are usually dark brown and do not have a logo medallion or sticker. The only manufacturer identification is at the bottom corner of the data plate, as shown above. Older models may also only be identified by BDP Company. The second two numbers in the serial number are the year of manufacture, so the serial number below indicates the condenser was manufactured in 1995.
