Ruud HVAC Age by Serial Number
Enter the serial number from your Ruud furnace, AC or heat pump's data plate to get its manufacture date, remaining life, warranty and recall status, and a repair-or-replace recommendation.
How to read a Ruud serial number
We can decode serial numbers from Ruud furnaces, ACs and heat pumps built 1992–2026.
2009–2026 format
Ruud furnaces, air handlers, air conditioners and heat pumps made since 2009 have a serial that starts with a factory letter, then two digits for the week and two for the year, then five more digits. For example, W291013412 was made in week 29 of 2010.
1992–2008 format
Older Ruud furnaces and air handlers (1992 to 2008) have a letter M in the middle of the serial. The two digits after the M are the week and the next two are the year, so OR177M280700097 was made in week 28 of 2007.
1992–2026 format Corroborated
Many older Ruud air conditioners, heat pumps and furnaces have a factory letter (F, N, G or W) in the middle of the serial. The two digits after the letter are the week and the next two are the year, so 7259F270614277 was made in week 27 of 2006.
Rheem documents this layout for its own units, and a dated Ruud plate and independent references agree Ruud units use it too. Treat the date as likely rather than certain.
2009–2026 format Corroborated
Ruud units made after 2008 with a letter M in the middle of the serial are read the same way: the two digits after the M are the week and the next two are the year.

Is my Ruud furnace, AC or heat pump still under warranty?
- Air conditioners: Most Ruud air conditioners (e.g. RA13, RA14, RA15 series): 10-year parts and compressor warranty if registered within 90 days, 5 years if not. UA16AZ, UA18AZ and UA19AY get 10 years either way, plus a conditional 10-year unit replacement.
- Heat pumps: Most Ruud heat pumps (e.g. RP14, RP15, RD16 series): 10-year parts and compressor warranty if registered within 90 days, 5 years if not. UP16AZ, UP18AZ and UP19AY get 10 years either way, plus a conditional 10-year unit replacement.
- Furnaces: 10-year parts warranty if registered within 90 days, 5 years if not (10 years either way on the U98MV, U97MV and R962V). Most current Ruud gas furnaces have a limited lifetime heat exchanger warranty for the original owner; the R801 series has 20 years.
Ruud furnaces, air conditioners and heat pumps: register within 90 days of installation to get the longer 'conditional' coverage (usually 10 years on parts); unregistered, many models get 5 years. If you can't show the installation date, coverage starts 90 days after the manufacture date in the serial number.
Ruud furnace, AC or heat pump recalls
Recalls come from the U.S. Consumer Product Safety Commission. Decode your unit above to check whether its model and serial fall inside a recall.
Should you repair or replace it?
Once you decode your unit, we compare its age against its typical life, a typical major repair against the cost of replacing it, and, with your model and state, what a new unit would save on energy. A common rule of thumb: if a repair costs more than about 30–50% of a replacement and the unit is past mid-life, replacing usually wins.
