Midea Serial Number Lookup
Midea has its own serial number format, not shared with another brand. Enter the serial from the data plate below to get the manufacture date with a character-by-character explanation, the unit's age, its refrigerant era, and the warranty picture.
Starting the decoder. The serial formats, the refrigerant timeline and the warranty terms further down this page are already loaded, so you can read yours off them now.
7 of the 41 decode rules rest on a single secondary reference. Where two agree, that is weaker evidence than it looks: secondary references copy one another, and agreement between two is not a manufacturer document being read. These rules rest on secondary references rather than on a document from the company that built the unit. Where two or more cover the same format we cross-check them against each other. A date stamped or printed on the data plate always outranks a serial decode.
Midea Serial Number Formats
| Format | Era | Example | Confidence |
|---|---|---|---|
| Leading V, then the 2-digit year in the first digit pair (or the second pair on some models)A single secondary reference, not a manufacturer document. Single source. | ~2010s to present | V193157328 = 2019 | low |
Some older or conflicting Midea formats are recognized but deliberately not decoded; the decoder explains why when it sees one instead of guessing.
Worked Example: Midea V193157328
Expected decode: 2019. Character by character:
19 = year 2019 (first digit pair after V)
Single-sourced rule; verify against the data plate.
Midea Refrigerant Timeline
| Manufacture year | Typical refrigerant | Notes |
|---|---|---|
| through 2024 | R-410A | Midea-built US residential systems ran R-410A through 2024. |
| 2025 and later | R-32 or R-454B (varies by product) | Midea supplies both R-32 and R-454B products; no single brand-wide choice is verified. Its US customer MrCool chose R-454B. Check the specific product's spec sheet. |
The refrigerant printed on the nameplate is authoritative; this timeline tells you what is typical for the age, not what is in a specific unit.
Midea Warranty Terms
Midea warranty lookup
No page of Midea'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 Midea 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.
What this tool holds on Midea's warranty
Midea America's central split system certificate (Rev 12.2024) gives residential units 5 years on parts and 7 on the compressor, and 12 years on both if registered within 60 days of installation, on the models it lists; commercial use gets 1 year on parts. Midea window units carry shorter terms (its MAW08 window unit prints a one-year limited warranty), so the certificate for the model governs.
The result does not work out a dated term for Midea: no Midea certificate is registered for that here. Only the maker's records show whether a unit was registered.

Frequently Asked Questions
How old is my Midea unit?
Decode the serial number from the data plate. The dominant Midea format (~2010s to present) is: Leading V, then the 2-digit year in the first digit pair (or the second pair on some models). Example: V193157328 decodes to 2019. Subtract the decoded year from the current year for the age.
How reliable is the Midea serial decode?
The main Midea rule carries low confidence, so treat the result as an estimate to check against the data plate. Single-sourced rule; verify against the data plate.
Has the Midea serial decode been checked against serials somebody else dated?
No serial with a date published outside this tool has produced a reading through the Midea V-prefix 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.
Read the date off the data plate and treat this reading as an estimate.
What refrigerant does a Midea unit use?
By manufacture year: through 2024: R-410A; 2025 and later: R-32 or R-454B (varies by product). 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.
How do I look up my Midea warranty?
No page of Midea'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 Midea 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.
Is my Midea unit still under warranty?
Midea America's central split system certificate (Rev 12.2024) gives residential units 5 years on parts and 7 on the compressor, and 12 years on both if registered within 60 days of installation, on the models it lists; commercial use gets 1 year on parts. Midea window units carry shorter terms (its MAW08 window unit prints a one-year limited warranty), so the certificate for the model governs. The result does not work out a dated term for Midea: no Midea certificate is registered for that here. Only the maker's records show whether a unit was registered.
Why do some Midea serial numbers refuse to decode?
This is Midea's US factory code (54 followed by twenty characters, the shape Midea America's own product registration checks). Which characters carry the manufacture date is not given in any Midea document this tool holds, so it does not decode it. Check the data plate or the installation paperwork. Midea 22-digit serials have two conflicting published readings that disagree on both the year and the month position. One traces to a Midea representative, the other to a secondary reference. This tool will not guess between them; check the data plate or the installation paperwork.
How old is my Midea furnace?
No maker document held here dates Midea furnaces, so the tool does not call a date a Midea furnace's age; it reads the serial by the same rule it uses for Midea's other equipment.
