HVAC Serial Number Lookup
Midea Serial Number Lookup
Midea is part of the Midea. 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.
Decode schemes compiled from manufacturer literature and inspector references, cross-checked across two sources wherever possible (Midea sources: howtolookatahouse only (single source)). Single-sourced rules are labeled low confidence instead of being presented as fact. 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) | ~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.

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. Units past 15 years are replacement candidates, and past 20 a major repair rarely pays off.
Why can a Midea serial number decode to more than one date?
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.
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.
Is my Midea unit still under warranty?
No authoritative US-wide Midea residential HVAC warranty page exists. Check the terms your distributor published for your specific series. Decode the manufacture date above, then confirm coverage by running the full serial through the manufacturer's own warranty lookup. Terms shown are the current policy; older units often carried different terms.
Why do some Midea serial numbers refuse to decode?
Midea 22-digit serials have two conflicting documented readings (a Midea rep quoted on the InterNACHI forum vs building-center's MrCool notes) that disagree on both year and month positions. This tool will not guess between them; check the data plate or the installation paperwork.
