Manufacturers encode a lot of information into the model number of the HVAC equipment they produce. The model number can be found on the manufacturer’s sticker on the side of the RTU. If the sticker is faded by years of sun exposure, it can often be found somewhere within a panel too. This blog will help provide older York RTU Model Number DCE Decoding. Additionally, this blog also speaks to older York Model DCG, DHE, and DHG RTUs. And by the way, equipment serial numbers also provide useful information.

York manufactures a variety of packaged HVAC units for light commercial applications. A RTU is also known as a packaged unit. For more information about York RTUs, or any of their residential HVAC systems, refer to their company website. York RTU information is available here on the York website.

The older York RTU described in this blog is shown in the photo below. This unit was manufactured in 1992.

The Manufacturer Sticker

The manufacturer sticker for an older York RTU model number D2CE048A46C is shown below. Also shown on the sticker is the serial number of NBAM109317. The manufacturer sticker is usually found on the outside of one of the panels on the RTU. It should be noted that this particular older York RTU is unusual. This unit uses electric heating elements instead of a traditional natural gas fired burner assembly. The majority of RTUs that we install and work on have gas burner assemblies for heating.

Decoding the Older York RTU Model Number DCE

York Model DCG and DHG RTUs are packaged units with both a gas heating furnace and a cooling unit. Gas furnace efficiencies are rated in AFUE. Gas furnaces have a number of auxiliary equipment items not used in electric heating units. For example, a gas valve, burners, a heat exchanger, an inducer, burners, and a flame ignition and sensing system.

York Model DCE and DHE RTUs are packaged units with both an electric furnace and a cooling unit. This blog describes how air conditioners dehumidify.

The model number for this particular York RTU example is shown below.

D2CE048A46C

D – the first digit refers to the product category, which is a packaged air cooled air conditioner and here, packaged means this is a rooftop unit

2 – the second digit refers to the equipment generation

  •             2 = second generation equipment
  •             3 = third generation equipment
  •             5 = fifth generation equipment
  •             6 = sixth generation equipment
  •             8 = eighth generation equipment
  •             9 = ninth generation equipment

 

CE – the third and fourth digits are a product identifier with the following meaning

CE = Cooling unit, where this unit can be fitted with electric heating elements

CG = Cooling unit with an integral gas furnace for heating

 

Unit Tonnage

048 – the fifth, sixth, and seventh digits refer to the nominal tonnage of cooling capacity

036 = 3 ton unit

048 = 4 ton unit

060 = 5 ton unit

072 = 6 ton unit

 

A – the eighth digit describes the factory installed heating components

A = Cooling only installed at the factory (Field installation of electric heating elements is an option)

N = Natural gas furnace is installed from the factory

 

46 – the ninth and tenth digits refer to the voltage code for the unit

25 = 208/230-3-60

46 = 460-3-60

58 = 575-3-60

 

C – the last digit is a product identifier that has a variety of meanings

 

Note that gas fired furnace models have an extra three digit designator in the ninth, tenth, and eleventh positions between the factory installed heat digit and the voltage code digits. This three digit code refers to the nominal gas heating output capacity of the gas furnace.

  • 040 = 40,000 BTU/hr
  • 060 = 60,000 BTU/hr
  • 079 = 79,000 BTU/hr
  • 099 = 99,000 BTU/hr

Older Unit Serial Numbers

The serial number on this rooftop unit NBAM109317 has month and year of manufacture embedded in the number. The coding for these units is not intuitive however. The 2ndand 3rddigits of the serial number, or B&A in this case indicate the month and year. The month code of B refers to February. The year code of A refers to either 1971 or 1992. In this case, this unit was built in the 1990s based on personal experience with these units.

Older York RTU Model DCE, DCG, DHE, and DHG Serial Number Decoding Image

Serial numbers of all manufacturers imbed date of manufacture and other useful information in a variety of ways. Of course, even among a single manufacturer, the serial number format may vary. A handy website that breaks down serial number information is the Building Intelligence Center at http://www.building-center.org. Click on the HVAC Index option.

Then go to the appropriate HVAC directory or Water Heater directory depending on the appliance type.

And select (click) the letter the brand in question begins with.

Then the selection will take you to that specific page where one or more examples of serial number styles will be listed on the information slide images.

The York serial number image above was obtained from the Building Intelligence Center website as an example.

If it is just the year of manufacture that you are interested in, refer to the manufacturers sticker.

The last line of data on the lower right corner of the sticker shows Rev A MFD0292. This indicates the unit was manufactured February 1992.
