For HVAC pros, what does the model number and serial number define about my Goodman HVAC Unit?
Question:Can someone explain the following model and/or serial numbers to my Goodman HVAC Unit ?
Model: CKJ30-14
S/N: 9811477121
Answers:
It is a 2-1/2 ton 12 seer unit that has been discontinued! Also it shows in the book to be a CKJ30-1A not a -14. The CKJ is just a designation the 30 means 30,000 BTU's (12,000 = 1 ton) and the 1A is also a designator. All of these numbers are identified in a Goodman catalog and also give you the SEER rating of the unit. Service men are usually concerned with the tonnage of the unit only, unless they have to replace it. Then they use these numbers to match it to an evaporator. Hope this answers your question.
it is a 2 1/2 ton unit 12 seer this is what the model number indicates..ckj is the designator for the guide to the unit..30 being the tons for the unit at 12000 btu's per ton...the 14 should be 1a and this indicates a revision or change to the original unit ckj30...the serial number.usually the numbers here indicate the year month and day it was made the line it was made on and who inspected the unit
The condensing unit was manufactured in the 11th week of 1998. Being a Goodman brand, it tells the tech that it was purchased by someone on a very limited budget, or they were a contractor who wanted a unit attached to the house they were selling.
