Erika
Great question.
When the data tag is lost and we want to know the age on a heat pump we have a few options:
1. how old is the building - that sets a limit on the heat pump age
2. are there any service records for the unit? If there are just one or two service or installing companies where you live you can also give them a call to see if they installed the unit
3. is there an installation manual left with the unit - often there's an installation date written there
4. did anyone pen an install date inside the cover
5. Identify the brand, take photos, ask the manufacturer for a clue - e.g. there may be a serial number on the compressor motor or other major parts

My. Serial number is gone on my heat pump so now how do I no how old it is?

If you can find the brand of your equipment on the data tag that combined with the serial number that you already have will allow you to look up the age decoder in this article series

I'm trying to locate a model/serial number for a condenser coil in my outdoor condensing unit in my mobile home. Manufacture date of mobile home is 1/29/2002. By looking at compressor number a fried suggested condenser coil may have been made by Comfortmaker. But not sure.
Have the compressor model/serial numbers by Copeland: Model: CR38K6-PFV-130; Serial: 02J03603H. The Fan model is by Emerson: K48HXFCM-3726. Also have a torn label for outdoor ambient temperature reading with a style number: NAC042.
The other label deals with electrical connection and is partially hidden and cannot see. I would appreciate the help if you can find out. thank you.

I'm trying to determine the age of my a/c unit. The serial # is 1601F26891. Can you help with this/(Jan 24, 2014) Jill Holstein said:
HOW CAN I GET ONE OF THESE ? Carson Dunlop provides a manual that decodes more of that data so that you can know the age of the compressor or air handler. That is, the date of its manufacture,
Jill contact information for Carson Dunlop Associates data tag decoding book is given in the article AGE of AIR CONDITIONERS & HEAT PUMPS as well as at the Citations at the end of this article.
Click the "Click to Show or Hide Citations and References" at the end of this article.
Scroll down to the second major bullet where we describe "Carson Dunlop Weldon & Associates'Technical Reference Guide to manufacturer's model and serial number information for heating and cooling equipment
" - the company's contact and sales information is there as a hyperlink, and they have generously provided a code (capital letters, bold face) that will get you a small discount on the price of that manual.

it is true that units capacity is calculate by compressor LRA Compressor? which we received model number # SM125S4CA, LRA-120 requested existing Compressor model # SM125S4CC, LRA-260. can it be used even LRA are different but BTU are the same?

Rocky,
Sorry, no, refrigerant capacities are not in the guide. It is used for product identification to year etc. Some model codes indicate refrigerant type but not the charge quantity - that is installation dependent, for example because piping length and thus charge volume will vary from job to job.
On 2012-09-18 by Rocky Germani
I am interested in knowing if the Carson Dunlop Technical Reference Guide covers Commercial Carrier AHU's RTU's and FCU's.
Also does it include refrigerant type and capacities for each unit. If not is there a site that does have the information. I am working for a college and am in need of this type of information if available. I am also interested in report writing.

Normally we'd look up the Magic Chef model number decode for your unit in our copy of Carson Dunlop's Technical Reference Guide (listed in the references section at the end of this article) but I'm working on assignment out of office for a time. You can
- contact Magic Chef and ask them directly
- pick up a copy of Carson Dunlop's Technical Reference Guide (recommended)
- pick up a copy of Preston's HVAC decoding guide (absurdly expensive, more details)
Typically on older Magic Chef AC equipment the year and place of manufacture are in the end of the serial number; the BTUH capacity is in the model number but may be encoded.

Andy, the compressor type may be coded in the model number for some manufacturers. If you pass on that data to me, better yet, with a sharp focus photo of the data tag(s) I'll see what I can find.
On 2012-05-08 by Andy Tran
Hi Dan. Great Info. Do you know if there is way to determine whether the compressor is a 2 stage or 1 stage unit based on looking at the data plate? Thanks a lot, Andy - Carson Dunlop.

What is the calculation for the additional charge of R410A for a sanyo SPWUR484GXH56 outdoor unit with pipe runs as follows:1" - 56M/0.375" - 31M and 0.25" - 9M

John that's an interesting question. The LRA is the current drawn just for a moment at startup; But if your generator cannot handle that brief surge the A/C may simply fail to start.
On 2011-08-31 by john
Do I need to consider the full LRA when choosing a generator for back up power?
