How can I tell the age of a Bard heat pump or air conditioner from the serial number?
Saturday, July 21, 2018
Bard is the best-known brand of wall-mounted package units in our area. In fact, sometimes we hear contractors say “Bard unit” as a generic term for any wall-mounted package air conditioner. They are most often used for small to mid-size commercial buildings, but we occasionally see them installed in residences. Here’s a chart for decoding the serial number.
The data plate can be a little hard to read as it gets older. The serial number on this one is 93H860440715. It fits the format for 1980 to the present, and the first two digits after the single letter are the year of manufacture: 1986.
And here’s a newer example from 2014.
To find out the age of another brand of air conditioner or heat pump, go to How do I determine the age of my air conditioner?, which has a listing of all major manufacturers and links to instructions for decoding their serial numbers.
