ICP HVAC Age by Serial Number
Enter the serial number from your ICP 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 an ICP serial number
We can decode serial numbers from ICP furnaces, ACs and heat pumps built 1990–2013 and 2015–2026. We can't decode units built in 2014 yet.
2000–2013 format
ICP builds Heil, Tempstar, Comfortmaker, Arcoaire, KeepRite, Day & Night and Airquest units, and their serials come in two layouts. Serials that start with a letter: the letter is followed by the two-digit year and then the week of the year, so L004112345 was made in week 41 of 2000. The last five digits are a sequence number. We can't yet date letter-first serials from 2014 or later.
1990–1999 format Corroborated
Inter-City Products units from the 1990s (sold as Heil, Tempstar, Comfortmaker, Arcoaire, KeepRite and others) use the same layout: a letter, then the two-digit year and the week of the year, then five digits. For example, R920500318 was made in week 5 of 1992.
ICP documents this layout for its 2000s units, and independent references, including 1990s data plates with a printed build date, agree that 1990s Inter-City Products units use it too. Treat the date as likely rather than certain.
2015–2026 format
Serials that start with four digits: the first two digits are the week and the next two are the year, so 0118E00001 was made in week 1 of 2018. The fifth character is a letter for the factory, followed by a five-digit sequence number.

Is my ICP furnace, AC or heat pump still under warranty?
- Furnaces: 10-year parts warranty if registered within 90 days of installation; 5 years if not. Heat exchanger coverage is 20 years, or lifetime on some models if registered. Top models (97% and two-stage lines) also carry a No Hassle Replacement warranty of 5 or 10 years for the original owner.
- Air conditioners: 10-year parts warranty, compressor and coil included, if registered within 90 days of installation; 5 years if not. Later owners get 5 years. Variable-speed and two-stage models add a 10-year No Hassle Replacement warranty, mid-tier models 5 years.
- Heat pumps: 10-year parts warranty, compressor and coil included, if registered within 90 days of installation; 5 years if not. Later owners get 5 years. Top heat pump models add a No Hassle Replacement warranty.
Register within 90 days of installation to get 10-year parts coverage; without registration it is 5 years. One ICP registration site covers Heil, Tempstar, Comfortmaker, Arcoaire, KeepRite, Day & Night and Airquest. Registration is not required in California, Quebec and other places that don't allow it as a condition.
ICP furnace, AC or heat pump recalls
- Upflow Horizontal Oil Furnaces Recalled by The Ducane Company (oil furnaces made by Ducane; Inter-City Products (Arcoaire, Comfortmaker) brands) (1996)
- CPSC, International Comfort Products LLC Announce Recall to Repair "Packaged Gas Electric" Heating and Cooling Units, or "Gas-Packs" (packaged gas-electric units) (2005)
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.
