Model number vs. serial number
The model number identifies the ICP product family and configuration. The serial number distinguishes the individual unit and is the value SerialAtlas uses for a manufacture-date estimate.
Record both lines from the same rating plate. Do not use an ICP model number as if it were a serial number, and do not infer a model specification from a serial code unless the exact manufacturer pattern documents it.
| Label field | What it is for | How SerialAtlas uses it |
|---|---|---|
| Serial number | Identifies one physical unit | Date-code input and rule explanation |
| Model number | Identifies product family and configuration | Optional context; not the date-code input |
| Full rating plate | Connects brand, model, serial, and safety fields | Primary record to verify before relying on a result |
How the ICP serial date example is read
The documented-style example E142320733 uses the common ICP plant/year/week layout: E is the plant character, 14 is the two-digit year, and 23 is the production week.
That pattern is a rule-family example, not a promise that every ICP-family or imported product uses the same positions. If the full label does not fit, leave the result unconfirmed and use the official support path.
Warranty and registration limits
A manufacture-date estimate is not an ICP warranty lookup result. Coverage can depend on the exact model, registration, ownership, installation, terms, and the manufacturer record.
SerialAtlas does not promise coverage, publish a universal warranty duration, or replace ICP registration and support records. Use the full model and serial with ICP or an authorized professional before making a claim.
ICP lookup questions
How do I read an ICP serial number? Start with the brand and full rating plate, then compare the serial to the documented rule shown above. Keep alternatives visible when the two-digit year could describe more than one era.
Can an ICP model number tell me the unit age? Not by itself. Use the serial number for the date estimate and the model number for product-line context.

Model number vs. serial number guide Where to find an HVAC serial numberUse the official ICP registration route for an existing record
ICP provides separate paths for a new registration and for managing an existing registration. Its registration search asks for the last name plus a confirmation number or serial number. Enter those details only on the official ICP site; SerialAtlas does not retrieve your registration.
A registration search is different from decoding a manufacture week. Keep the full model and serial from the rating plate, and do not treat a decoded age as proof of coverage.

How to read a International Comfort Products serial number
A plant letter is followed by a two-digit year and two-digit production week (LYYWW). SerialAtlas removes spacing and punctuation, then applies only the documented rule families mapped to International Comfort Products. The lookup remains in the browser.
Equipment covered
- air conditioners
- heat pumps
- furnaces
- air handlers
- packaged systems
Commercial, imported, very old, specialty, and private-label equipment can use a different code. Confirm the full rating plate before accepting a result.
Where to find the rating plate
- Outdoor condenser or heat-pump cabinet, usually near the service valves
- Inside the furnace or air-handler access panel
- On the packaged-unit rating plate
- Near the electrical disconnect or wiring diagram
Why more than one date can appear
Two-digit years and repeating letter cycles can point to more than one era. SerialAtlas ranks the plausible dates but keeps materially different alternatives visible. Label design, refrigerant, installation records, and product literature can resolve the era.

A manufacture date is not an installation date, warranty decision, recall match, condition assessment, or replacement recommendation. Confirm high-stakes decisions with the manufacturer or a qualified professional.
