When Fort Smith production was "on line" Kalamazoo production stopped soon after. When the Division was established, about that same time the NEW Fort Smith, Arkansas plant was finished being built and production began there soon afterwards, operations transfered to the Newly built facilities right away. (The period was approximately late 1962 or early 1963 up to approximately 1973. At the time this furance was manufactured it was under the "Home Products Group" and before the creation of the Air Conditioning and Heating Division was established. It was manufactured during the time that ALL the Air Conditioning and Heating OPERATIONS were directed (not necessarily manufactured at, but in this case it was) from Kalamazoo, and this furnace hapened to be manufactured there as well. This furnace was manufactured at the Kalamazoo, Michigan Plant. He was off slightly on the month of production certification - it was September, the 9th month.Ī little history about the former Rheem entity,Īt the time this furnace was manufactured Rheem was still a California corporation, not the Delaware corporation it is today, a few controlling interest owners later. Jerry Peck had the year correct, it is 1969. The method of four digits which follow an "F" as to date for a Rheem furnace didn't begin until the Air Conditioning and Heating Division was established as a split off from the Rheem Home Products Group, and that didn't happen until late 73 or early 74. ScottSorry, but you are absolutely wrong about a Rheem Furnace made prior to 1973, and this was!
Rheem serial look up serial number#
The 2287 portion of the serial number is definitely the date code, indicating that the furnace was manufactured during the 22nd week of 1987. Some of the products we handled were manufactured by Rheem. From 1983 to 2007 I worked as a salesman / manager / warranty administrator / technical specialist for two of the largest HVAC/R wholesalers in the area. I currently work as a commercial HVAC and refrigeration estimator for a Baltimore / DC area contractor. Standing pilot gas furnaces such as the one pictured above were typically rated at 60% to 65% efficiency without a motorized vent damper and up to 70% with the motorized damper. Effective on January 1, 1992, it set the standards at a minimum value of 78 percent for most furnaces, 75 percent for gas steam boilers, 80 percent for other boilers, and 75 percent for mobile home furnaces." "Efficiency Standards History: The National Appliance Energy Conservation Act of 1987 (NAECA) established the initial minimum efficiency standards for furnaces and boilers, in terms of the annual fuel utilization efficiency (AFUE). when did most units come with electrical ignition lighters?From DOE info: But, it much change the fact that your unit is a senior citizen of the HVAC world.įor, others. I see a lot of Rheem and GE furnaces that are still running from your time-frame. Definitely not from the 80's when units like this became self-igniting with ignition devices. (Here comes the debate about replacing something which is "old" but which is "working", and this is typically brought up by people who so broadly define "working" to include units which are totally rusted out but the fan blade is turning under its own power and they can see the bubbles in the refrigerant line 'sight' chamber moving so they know the compressor is moving the refrigerant, therefore the unit is 'working'. If it does not look 40 years old (how old is the house?, does it look original to the house?), then I would go to the four separate numbers, and state in the report that the age of the unit could not be determined, but that the unit is old and is likely in need of replacement.
Rheem serial look up serial numbers#
So I went back to the way some used to identify their units: the first sequence is some of the serial numbers used to be letter for the plant it was manufactured at, another letter for the month of manufacture, and two numbers for the year of manufacture - thus my 11/1969 mentioned above. like you said, there is no letter in front of those four numbers, so. The letter indicated the plant at which the unit was manufactured and the four numbers which followed were the week and the year, but. However, my serial has no "F".Īs I recall, the newer ones had a letter followed by four numbers which were typically in front of the serial number.
but now I'm wondering if it's the date code.Įvery place I look for Rheem serial number decoder rings says that the 4 digits after the "F" in the number are the date code.
Since the "2287" is off by itself, I first thought maybe it was the sequential build number.
