Mitsubishi Electric
Mitsubishi Electric is a Japanese manufacturer of electrical and electronic equipment, including air conditioning and heat pumps. Its UK M Series wall-mounted range is published with product information sheets on the company's UK site, and those sheets are the source of the figures shown here.
Premium
Principal bedrooms, main living rooms and consulting rooms where air quality and quiet both matter.
Available sizes
2.5 · 3.5 · 5.0 · 6.1 kW

Specifications come from manufacturer documentation. Where a row is ACE Climate’s own view rather than a published figure, it says so. We do not rank these against each other — which one suits you depends on the room, the building and the budget, and that comes out of a survey.
| Specification | Mitsubishi Electric M Series MSZ-LN (Premium) MSZ-LN25VG3 | Mitsubishi Electric M Series MSZ-LN (Premium) MSZ-LN35VG3 | Mitsubishi Electric M Series MSZ-LN (Premium) MSZ-LN50VG3 | Mitsubishi Electric M Series MSZ-LN (Premium) MSZ-LN60VG3 |
|---|---|---|---|---|
| Cooling capacityThe range of cooling capacities this model is available in — the cooling delivered, not the electricity used. Which one suits a room depends on a heat-load assessment of that room, not on floor area alone. | 2.5 kW | 3.5 kW | 5.0 kW | 6.1 kW |
| Heating capacityPresent when the system can heat as well as cool. In heating mode it works as a heat pump, moving heat in from the outside air rather than creating all of it. | 3.2 kW | 4.0 kW | 6.0 kW | 6.8 kW |
| Series | M Series MSZ-LN (Premium) | M Series MSZ-LN (Premium) | M Series MSZ-LN (Premium) | M Series MSZ-LN (Premium) |
| System typeHow the system is put together. A single split serves one room from one outdoor unit. A multi-split serves several indoor units from one outdoor unit. VRF — variable refrigerant flow — is the larger commercial version, where one outdoor unit serves many indoor units that can run independently of each other. | Single split | Single split | Single split | Single split |
| Indoor unit style | Wall-mounted | Wall-mounted | Wall-mounted | Wall-mounted |
| Efficiency, cooling (SEER)How efficiently each system cools across a typical season, as published by the manufacturer. A higher number normally means the same cooling for less electricity, which makes this the fairest single row for comparing two systems of similar capacity. It is not a prediction of a bill — that also depends on the building and how the system is used. | 10.5 | 9.5 | 8.5 | 7.5 |
| Efficiency, heating (SCOP)The same idea as the row above, but for heating across a typical season: higher generally means more heat for each unit of electricity used. Present only where the system can heat. | 5.2 | 5.1 | 4.6 | 4.6 |
| Energy labelAs printed by the manufacturer. The scale differs by capacity band, so two labels are only comparable within the same band. | A+++ / A+++ | A+++ / A+++ | A+++ / A++ | A++ / A++ |
| Sound leveldB(A) is a measurement of sound, and the scale is not a straight line — a difference of a few dB(A) is more noticeable than the numbers suggest. Manufacturers quote under their own test conditions, so treat these as a guide to relative quietness rather than as directly comparable numbers. | 19 dB(A) in Silent (SLo) mode, up to 45 dB(A) at full speed. At its ordinary low fan speed it is 23 dB(A). Measured as the manufacturer publishes it: SLo ("Silent"), the lowest of the five published fan speeds. Cooling SLo-Lo-Mi-Hi-SHi 19-23-29-36-42; heating 19-24-29-38-45. Lowest published across both modes recorded. Highest of the five published fan speeds (SHi), cooling. Lo, the ordinary low fan speed — one step above Silent. Cooling 19-23-29-36-42; heating 19-24-29-38-45. | 19 dB(A) in Silent (SLo) mode, up to 45 dB(A) at full speed. At its ordinary low fan speed it is 24 dB(A). Measured as the manufacturer publishes it: SLo ("Silent"), the lowest of the five published fan speeds. Cooling SLo-Lo-Mi-Hi-SHi 19-24-29-36-43; heating 19-24-29-38-45. Lowest published across both modes recorded. Highest of the five published fan speeds (SHi), cooling. Lo, the ordinary low fan speed — one step above Silent. Cooling 19-24-29-36-43; heating 19-24-29-38-45. | 25 dB(A) in Silent (SLo) mode, up to 47 dB(A) at full speed. At its ordinary low fan speed it is 29 dB(A). Measured as the manufacturer publishes it: SLo ("Silent"), the lowest of the five published fan speeds. Cooling SLo-Lo-Mi-Hi-SHi 27-31-35-39-46; heating 25-29-34-41-47. Lowest published across both modes recorded. Highest of the five published fan speeds (SHi), cooling. Lo, the ordinary low fan speed — one step above Silent. Cooling 27-31-35-39-46; heating 25-29-34-41-47. | 29 dB(A) in Silent (SLo) mode, up to 49 dB(A) at full speed. At its ordinary low fan speed it is 37 dB(A). Measured as the manufacturer publishes it: SLo ("Silent"), the lowest of the five published fan speeds. Cooling SLo-Lo-Mi-Hi-SHi 29-37-41-45-49; heating 29-37-41-45-49. Lowest published across both modes recorded. Highest of the five published fan speeds (SHi), cooling. Lo, the ordinary low fan speed — one step above Silent. Cooling 29-37-41-45-49; heating 29-37-41-45-49. |
| Indoor sound pressureSound pressure is how loud the indoor unit is at a stated distance — the figure closest to what you would actually hear. This is the quietest each manufacturer quotes, measured under its own conditions; see the row above. | 19 dB(A) | 19 dB(A) | 25 dB(A) | 29 dB(A) |
| Smart / Wi-Fi control | Yes | Yes | Yes | Yes |
| Smart control platformWhat a unit can be controlled BY — an app, a voice assistant, a building management system. Separate from Wi-Fi, which is only how it connects. | Yes | Yes | Yes | Yes |
