Sure Comfort Serial Number Lookup

Decode the serial number from the data plate. The dominant Sure Comfort format (~1990s to present) is: Letter + 9 digits; digits 2-3 = week, digits 4-5 = year (this format encodes week + year, not a month). Example: W291013412 decodes to week 29 of 2010 (mid-July). Subtract the decoded year from the current year for the age.

Sure Comfort is part of the Rheem family, alongside Rheem, Ruud, and WeatherKing. These brands come off shared production lines with the same data plates, so this page's serial number formats apply across the family. The refrigerant timeline above is stated for the whole family, not per brand. The warranty section above is this brand's own.

Rheem family letter + week-year: Read against 1 serial where a public body's own equipment schedule prints a year beside the serial (Winter Park, Florida; the year sits under a column headed Year, which the document does not define), air handling unit: 1 matched the reading shown first. This format was also read against 4 serials on water heaters (Winter Park, Florida): 4 matched the reading shown first. They are shown for the record and not counted toward this format's check, because the equipment is not a heating or cooling unit.

Rheem family digits-first 10-character: This format was also read against 3 serials on water heaters (Winter Park, Florida): 3 matched the reading shown first. They are shown for the record and not counted toward this format's check, because the equipment is not a heating or cooling unit.

Rheem family long serial (middle factory letter): Read against 3 serials where a public body's own equipment schedule prints a year beside the serial (Winter Park, Florida; Mobile, Alabama; the year sits under a column headed Year on 2, and under a column headed Year Manuf on 1, 2 of which the document does not define), 1 of them condensing unit, across 3 equipment types: 3 matched the reading shown first.

No serial with a date published outside this tool has produced a reading through the Rheem family 9-digit (date at the end) format yet. No document from the company that built the unit is held for it, so the rule rests on the secondary references this tool records.

Across the Sure Comfort formats on this page, 5 serials with a date published outside this tool produced no reading at all (Norcross, Georgia; Winter Park, Florida). A serial this tool reads nothing from is neither an agreement nor a disagreement, so it is counted in neither.

By manufacture year: through 2009: R-22; 2010 to 2024: R-410A; 2025 and later: R-454B. The refrigerant printed on the nameplate is authoritative; the year-based mapping tells you what is typical for the age, not what is in a specific unit.

No page of Sure Comfort's own for looking up a warranty is linked here, and this page does not read any maker's records, so it cannot show whether a unit was registered. Enter the serial in the lookup on this page for the build date and the unit's age. No Sure Comfort warranty certificate is held here for a dated term, so the result dates no term, says so, and names what would answer it; a Service Brief carries what is known to whoever works on the unit.

Current policy: 10-year conditional parts warranty on eligible residential models registered within 90 days of original installation or closing at RegisterMyUnit.com (original owner, original installation location; the newer certificates also require an owner-occupied single-family home); 5-year parts unregistered on most lines. Rheem certificates up to edition 92-26150-31-30 printed a 60-day registration window instead. Rheem's registration portal says Florida installs after March 31, 2024 and Georgia installs after December 31, 2025 qualify for the longest listed parts term without registering. WeatherKing certificate 92-26150-53-13 prints 5-year parts with no registered extension. The result does not work out a dated term for Sure Comfort: no Sure Comfort certificate is registered for that here. Only the maker's records show whether a unit was registered.

Rheem's own furnace parts list prints a furnace serial that begins with the "TYPE OF GAS CONTROL USED ON UNIT" and carries the plant letter F (the "Downflow/Horizontal Furnace" list). Enter the furnace's serial above: the result gives the date and age and says which document covers it. It covers serials of this layout: a two-letter gas-control code (DG, DH, DC, DF, EH, EJ, EK or EL), five more characters, the plant letter F, then the week and the year. A Sure Comfort serial of another layout is read as usual, and the result says the date is not called a furnace's age.
