How can I tell the age of a FHP (Florida Heat Pump) geothermal heat pump for the serial number? Saturday, June 23, 2018 The first letter of the serial number indicates the year of manufacture, starting in alphabetical order with “A” for 1971, but eliminating I, O, and Q, then recycling the letter code over again in 1994. One manufacturer builds 90% +/- of ALL the geo heat pumps in America. Look at the demensions. Look at the coil size. Look at the physical configuration. They are all the same. Florida Heat Pump (FHP)® How to determine the date of production/manufacture or age of FHP® HVAC Systems. The date of production/manufacture or age of FHP® HVAC equipment can be determined from the serial number located on the data plate. Never ask your air conditioner how old it is - we can tell you its age if you have a Rheem. Just drop in your AC's serial number, and you'll have its age instantly.

What Information is Provided by a Data Tag on an Air Conditioner or Heat Pump?The photo shown above is for a conventional (non-split) residential air conditioning compressor unit. Unless it has been painted-over or lost, on most air conditioners and heat pumps, a metal, foil, or plastic tag or data sticker is usually affixed to the outdoor air conditioner or heat pump compressor/condenser housing. Depending on the age and equipment manufacturerthe format and content of data on this tag varies, but typically the tag will allow you to discover some or all of the considerable amount of data listed here:
Modified, damaged, or torn air conditioning equipment information data tags can make age, capacity, and repair of any equipment more difficult. For the air conditioning compressor unit shown here, all we know is thatthe manufacturer was Singer. Model numbers and serial number appear to have been cut away from the data tag. Why? Sometimes when equipment data labels are removed or obscured a building buyer or a home inspector may raise a concern that the unit installed was different than that which the was ordered or that it is of questionable origin. On rare occasion that might be the case. But Ratib Baker, a member of member of Refrigeration Service Engineers Society (RSES), informs us that during the 1980's HVAC equipment manufacturers used a type of label which lacked UV resistance, faded, cracked, and eventually peeled away from the equipment, making equipment identification and ordering of replacement parts difficult. Mr. Baker wrote (October 2008) that in the 1980's 'the [HVAC compressor] label's protective mylar surface was damaged by the printing of the model and serial numbers and the electrical data which allowed the UV from the sun to destroy those areas. Upon discovering that they did not stand up to weather, most manufacturers started putting a second label inside the electrical compartment. Eventually better labels were designed, but some of the better manufacturers still put a second label in the unit.' Where a data tag or label on equipment is damaged or missing, check further for more label data including inside the unit's enclosure. Service technicians may have written the model and serial number data in indelible marker, or the manufacturer may have provided a second data label inside the unit - check HVAC equipment with lost or damaged labels to see if you can find that data elsewhere. You may also find equipment identification details in the installation and service manuals for the equipment if those have been kept in the building. Look around the indoor equipment for those documents. What we can say from the label in the photograph above is that by 2007 when the photo was taken by an ASHI inspector, this particular equipment was at least 23 years old - older than its usual anticipated life expectancy: the Singer brand On air conditioners was dropped in 1984. Alphabetical List of HVACR Air Conditioning & Heat Pump Equipment Data DecodersHere we focus on decoding the age of some HVACR equipment by finding that in the device serial number. Often the heating or cooling capacity is also encoded as a number (thousands of BTUs/hour) or a letter that decodes to a number. Details are in the age decoder guides given above. Often you will find very detaild data tag decoding help for your specific brand and model air conditioner or heat pump by consulting its manual.

Etc E = 1970, 1980, etc. BBryant Air Conditioner Data Tag Age DecoderAfter 1979, the week of production is encoded in digits 1 & 2 of the serial number, and the year of production is encoded in digits 3 or 3&4 of the serial number. Eg. 5214AX31929 decodes as week 53 of 2014 WWYAX12345 decodes as follows WW = sequential week within year, 01-52 Y = year as follows R S T U V W X or Y = 1964 -> 1971 (e.g. S = 1965) A B C D E F G or H = 1972 -> 1979 CCarrier Air Conditioner or Heat Pump Age Decoder![]() [Click to enlarge any image] Also see Carrier contact information and manuals at CARRIER Air Conditioners, Boilers Furnaces Carrier 1980-present: week and year are encoded in the first four digits of the serial number as WWYY1234567 Carrier equipment produced in the 1970's MY12345678 encoded the month and year as a letter (month) and single digit (year) where A=January -> M = December. e.g. A9xxxxxx = January 1979 Carrier equipment produced in the 1960's Y123456789 encoded just the year of manufacture as a single digit (year) in the first position of the serial number, e.g. 9xxxxxx = 1969. Reader Question: where is the SEER rating on my Carrier Condenser unit?(Jan 30, 2014) Kevin said: Is it supposed to be on the data tag somewhere? Reply:Good question, Kevin, thanks. No we do not generally see the SEER rating encoded nor explicit on an HVAC equipment data tag. Rather it is in the product literature. I THINK that a reason for this is that the net SEER rating for a given air conditioner or heat pump depends on how a combination of components operates together while certain individual components might be used in more than one set-up. Example: Carrier's Infinity Split System air conditioners are rated by the company at SEER 16.5 (Model 24ANB6) to 21 (Model 24ANB1) BUT for some manufacturers there is a clue to SEER right in the model number. The Infinity Model 24ANB1 is designated with MODEL NAME INFINITY21 while the Infinity Model 24ANB6, rated at a seer of 16.5 is designated with MODEL NAME INFINITY16. You can for this series only roughly approximate SEER by noting the model name. For example within the Infinity product line by Carrier, two Infinity Models designated INFINITY17 are rated at SEER 18. Adding honesty to SEER ratings, companies typically state in the product literature 'Up to SEER nn' recognizing that the actual energy efficiency in practice and in specific installations will vary. In advertising law, 'up to' claims, to be legally defensible, sport a number that must be met by at least ten percent of actual cases. In our article on SEER (search InspectApedia for the title Air Conditioning SEER Energy Efficiency Ratings Explained - HVAC Dictionary I will add this Q&A and if I can find more details I will elaborate there on where & how to find the SEER of your equipment - thanks again. Daniel OH - and if you give me the model number I'll dig up that specific seer.

Reader Question: age & data tag decoding for Command Aire equipmentI am looking to replace a 30+ year old cooling/heating wall convector from a New York high-rise apartment unit. Attached is the current unit in operation, and there a total of four (4) located in separate spaces within the unit. [Click to enlarge any image] Can you please tell me if you know what kind of a unit this is from the poor quality photo (Command-Air(?)), and if there are modern replacements I can look into that possibly can be controlled from a wall plate control next to a light switch (for example). - D.C. 8/21/2014 Fight alone, with your squad, and in hover tanks and mechanized walkers as you engage in a heroic mission into the heart of the Strogg war machine. In the game, you are Matthew Kane, an elite member of Rhino Squad and Earth’s valiant invasion force. Reply:I'm not what I'm looking at in your photo. But some basic information about wall convector units used for heating and/or cooling is at Typically in a high rise apartment the energy source for heating and cooling will be piped from a common building source. You'll want to know what your building supplies before thinking about replacing the equipment. Reader Follow-up:The photo was a poor shot of the model label sent by the contractor currently remodeling the apartment. The units are enclosed within a built-in wooden lacquer cabinet, similar to the attached photos show. I was trying to make out the unit name, and I believe it is an early 80’s Command-Aire model, about 62” wide by 12” deep. I’ve also attached a stand-alone model, with the controls on top beneath the grill. I’m not sure about the building supply details yet, since I have not received information from the contractor, but I’m just trying to find a comparably model to replace this unit(s). I believe the overall size and top diffuser gives me a head start to look into a Trane Type AK model, just to start comparing. Reply:Command Aire brand was later bought by Trane - so when you know what type and model you've got installed that'd be a place to start looking for a compatible replacement. When you have a clear image of the unit's data tag you'll see brand, model, serial number that will decode into just what is installed. There's little point in looking for equipment and prices before you know what kind of equipment works with your building's infrastructure. Coleman HVAC Data Tags

DEFFedders Air Conditioner or Heat Pump Age DecoderMonth and year are encoded as alphabetic letters in the last two positions of the serial number, beginning with A = September and A = 1966 GReader Question: age of a GE air condenser unitCould you help us determine the age of a General Electric central air condenser. Model TA36H1F01 S/N 205100925 This unit appears to be extremely old, but would appreciate any help you can give me. - John 6/1/12 Reply:John, Carson Dunlop's Technical Reference Guide has several pages of GE equipment data decoding information, including the observation that beginning in 1944 GE coded the age in the last three digits of the serial number, with the year in the third from last position. But the GE serial number codes on air conditioners & heat pumps used letters (N-Z = months Jan-Dec) and Year A-Y = 1944-1964, then repeated). Your serial number does not conform to the known codes for General Electric air conditioners. GE used letters not digits for month and year as I explained above. Is it possible you are mis-reading a letter 'Z' as a numeric '2' or a P or R as a '9' and an 'S' as a '5' ? Examples of troubles reading old fuzzy or partly obscured serial numbers or model numbers on HVAC equipment are in our article just above. So if your 2 and 5 are really SS the unit could be as old as May 1959 or perhaps more likely, as recent as 1980. Send us a sharp focused photo of the entire label if you can and I'll comment further.

Watch out for Confusing or Mis-Reading Letters & Numerals on Old HVAC Equipment Data TabsEspecially when equipment is old or has been located outside where its data tag can become obscured, faded, or damaged, it is easy to confuse as certain numeric digits some alphabetic characters, and vice versa. Our table below gives some confusion examples to watch for. So if information about model numbers or serial numbers for a given manufacturer specifies that that company use a mix of alphabetic and numeric characters (E.G. General Electric), and you see only numeric, look again to see if you're making a mistake.

The quickest way for most people to tell is if the thermostat has an 'emergency heat' setting. Most 'all electric' homes (no gas or propane service) are heat pumps, although some just use heat strips for heat.
