Mitsubishi Electric MSZ-AP

The MSZ-AP is the large-room end of Mitsubishi Electric's Elegance range, the brand's dependable everyday wall-mounted split rather than the designer MSZ-LN flagship. In the current UK line-up it covers only the 6.0 and 7.1 kW sizes; the 2.0 to 5.0 kW sizes most homes fit are now badged MSZ-AY. It is the one we would point towards for a big living room or open-plan space when solid build, quiet running and long-term reliability matter more than colour finishes and top-tier gadgets. Build quality is genuinely excellent, it runs from 30 dB(A) on its lowest fan speed, and its inverter performance is efficient for a unit this size, SEER 7.4 in cooling and SCOP 4.6 in heating on the 6.0 kW with an A++ energy label. SEER measures seasonal cooling efficiency; higher is better. It runs on R32, the lower-impact refrigerant now standard on quality splits.

What you give up against the flagship is features and a little polish. There is no Plasma Quad air purification, no 3D i-See occupancy sensor and no choice of colours, all of which are reserved for the pricier MSZ-LN, and the LN runs quieter still. Wi-Fi is now built in as standard on the current VGK2 generation, so the MELCloud Home app works out of the box; only older VGK stock needed an optional adapter. Like any fixed split it is supplied and fitted by an F-Gas certified engineer rather than bought off a shelf, so you work from a quote. At around 4.4 out of 5 it is a sensible premium choice: not the last word in features, but among the most reliable large-room splits you can have fitted.

The MSZ-AP is a wall-mounted R32 split system: an MSZ-AP indoor unit paired with an MUZ-AP outdoor condenser, or an indoor unit running on a Mitsubishi multi-split outdoor unit that serves several rooms. R32 is the lower-impact refrigerant now standard on quality splits, and any work on the sealed circuit has to be done by an F-Gas certified engineer, so this is a fitted product, not a plug-in one. In UK showrooms and installer quotes you will usually see it badged as the Elegance range, the plain white volume model that sits below the designer MSZ-LN. If you are still choosing a type, our guide to wall-mounted air conditioners covers sizing, noise, and fitted prices across the category.

Think of it as Mitsubishi Electric's dependable workhorse. It does not carry the flagship's headline features, there is no Plasma Quad purification, no 3D i-See occupancy sensor and no choice of colours, but it inherits the build quality and quiet running the brand is known for. It is efficient for a large-room unit, holding an A++ cooling label on both sizes, with seasonal figures of SEER 7.4 and SCOP 4.6 on the 6.0 kW (7.2 and 4.4 on the 7.1 kW), meaning it returns roughly four and a half units of heat for every unit of electricity. Its lowest fan speed is 30 dB(A), quiet for a unit shifting this much air, though the smaller MSZ-AY sizes go down to 18 dB(A) if you are cooling a bedroom.

In the current UK range it comes in two sizes, 6.0 kW (MSZ-AP60) and 7.1 kW (MSZ-AP71), for a large living room, kitchen-diner or open-plan space; the 2.0 to 5.0 kW sizes that used to carry the AP badge are now the MSZ-AY, which has the same Elegance styling with built-in Wi-Fi and a quieter 18 dB(A) minimum. It suits anyone who wants Mitsubishi Electric reliability and quiet at a sensible price in a big room and does not need the designer finishes or advanced air-quality kit. If those extras matter, step up to the MSZ-LN; if they do not, the MSZ-AP is the value pick for a large room.

The MSZ-AP is priced supplied and fitted, so there is no single shelf price. As a guide, Costco UK's installed Elegance 6.0 kW package was £2,399.99 for members in October 2026, and a 6.0 or 7.1 kW single-room install from a local installer on a straightforward pipe run typically lands around £2,400 to £3,200, with more for longer runs, high-level work or a multi-split setup. Unit-only prices for the current AP60 and AP71 are hard to find; the £755 to £900 2.5 kW listings still around online are previous-generation stock of a size now sold as the MSZ-AY. Always work from two or three live quotes for your own home before you budget.

Running costs are low for the comfort on offer. At the October 2026 Ofgem price cap unit rate of 26.32p per kWh, the 6.0 kW unit draws a nominal 1.59 kW at rated cooling output, so about 42p an hour working hard, dropping well below that once the room is at temperature and the inverter modulates down. In heating the SCOP of 4.6 means it returns more than four and a half units of heat for every unit of electricity, far cheaper than a plug-in heater giving the same warmth. As a reverse-cycle air-to-air heat pump the MSZ-AP may qualify for the £2,500 Boiler Upgrade Scheme grant in England and Wales from 28 April 2026, but only if it replaces an existing fossil fuel or electric heating system (gas, oil, LPG, storage or panel heaters) and is fitted by an MCS-certified installer; comfort cooling added alongside a gas boiler does not qualify, and it is separate from the larger £7,500 air-to-water grant. Prices correct as of October 2026; electricity rates updated for the October to December 2026 price cap. The energy price cap changes quarterly, so check current rates before budgeting.
