Try this topic which is on page two of this section. Rheem age please.


Prestons states that the RUUD by model # is between 1988-1995. Are you sure the serial # is correct?

contacted Armstrong at 1-800-448-5872


This is a 5 ton 10SEER unit manufactured in Jan 1999.

I have asked them for information about their serial number and model number configurations.

I'll pass it on if they send it.

Thanks,

Rick

Reads, 84=Jan, 99=1999.

What is the SN for the RUUD? Sounds original.

Never mind I see it now.

F0588 3754.... that is May 88.


Correct.

Don’t remember where i “borrowed” this from, but it is a decent guide for referral…



HVAC AGE CODES IN SERIAL # INFO
Rheem & Rudd: in the middle of the serial number will be a letter "F" the following four numbers are the week and year.

Carrier, Bryant, Payne, Day & Night: Recently (last 20 years or so) the first four numbers in the serial number represent the week and year. Previously, it was a complex series of letters and single digits. Call 905 672-0860 if you get stuck.

Lennox: Either the first two or second two digits are the year, it varies by era, but most of them actually have a separate sticker somewhere that has the year printed on it. Newer ones are first two equals manufacturing plant #, 2nd two are year and letter in fifth slot is month (A thru M minus I). So 5898G 07568 would be Plant # 58, Year of MFR would be 98 and month would be July.

Amana: BLACKHORSE. B=1971 or 1981. (Of course, now that they've been bought by Goodman, who knows what'll happen.)

Goodman: First two digits of the serial number are the year. Second two are the month.
Btu rating is model number..ie; GMP075-3 (75,000 bonnet input)
Compressor is same :serial # 9709088872 (yr1997 wk 09) Tonnage is model # CK361C The first two numbers after the CK (letters) divided by 12 is tons. ie: 36 div by 12= 3 tons.
