Mitsubishi Electric Dual Split Wall Air Conditioners

Which Mitsubishi Electric dual split wall air conditioner is right for your rooms?

A Mitsubishi Electric dual split wall system conditions two rooms from a single outdoor unit: two indoor units cool in summer and heat in winter with a heat pump, with one motor on the balcony and less clutter. The most requested combinations are 9+9, 9+12 and 12+12 BTU, with more than 200 configurations and prices from around 1119 euros. The Smart HR 9+12 series, with the MXZ-2HA40VF motor, is the most chosen. Browse the full Mitsubishi Electric range or, for a single room, the monosplit wall air conditioners.

Two rooms calling for cool air at the same time

The kids' bedroom and the living room that heat up together in July, the study and the master bedroom you want to keep cool without filling the balcony with motors. Fitting two separate monosplit units means two outdoor units and a double install: with a dual split you cover two rooms from one motor, less clutter outside and a tidier system.

The most popular Mitsubishi Electric series

The Smart HR series with the MXZ-2HA40VF motor (9+12 and 9+9) is the best seller, made for people who want Japanese reliability across two rooms. The MSZ-HR 12+12 combination with the MXZ-2HA50VF motor serves two larger rooms, while the MSZ-AY range with the MXZ-2F motor (9+12 and 12+12) steps up comfort and quietness. All use R-32 refrigerant and run as a heat pump.

Which combinations to choose per room

On a dual split, the key is matching each indoor unit's size to its room, keeping in mind they share a single outdoor motor.

• 9+9 BTU: two bedrooms or studies up to about 25 sqm each, ideal for the sleeping area;
• 9+12 BTU: one bedroom plus a living room up to about 35 sqm, the most chosen combination;
• 12+12 BTU: two medium, bright rooms up to about 35 sqm each;
• 12+18 BTU: one bedroom plus a large, very sunny open space.

How much does it cost to run?

This is the question that stops almost everyone. Inverter technology modulates the power instead of switching on and off, so it uses far less than an old unit; with R-32 refrigerant and an energy class up to A+++, the bill stays under control even with two rooms running all afternoon. On Mitsubishi Electric you pay a little more upfront, but the build quality means fewer faults and a longer service life.

It heats in winter too

Because it is a heat pump, the same units warm both rooms in the mid-seasons within minutes, often for less than two electric heaters running. For hot water instead, see the heat-pump water heaters.

Mitsubishi Electric and the connected home

With the Wi-Fi module you turn each room on from your phone before you get home and find them already cool, or control them independently by voice. Find all compatible models among the smart air conditioners for Alexa and Google Home.

Mitsubishi Electric versus other brands

Mitsubishi Electric is the premium choice for anyone who puts quiet operation and longevity first: for the same combination you pay a little more than brands like Hisense or LG, but you get quieter units built to last for years. It sits on a par with Daikin; to compare, also look at Samsung and Haier.

Incentives, warranty and support

Buying a high-efficiency heat-pump system may qualify for energy-renovation incentives depending on the schemes in force: keep your invoice and paperwork and check the current conditions. Every system ships with the official manufacturer warranty, delivery across the country and our help choosing sizes and kits. For three rooms, look at a trial split wall system or the whole range of wall air conditioners as multisplit, and check the deals on all air conditioners.
