White wall-mounted air conditioning unit we fitted high on a wall in a London room

Daikin vs Mitsubishi Air Conditioning

Daikin vs
Mitsubishi Electric

We fit both, so we have no reason to talk you into either. Both make excellent wall units, and the differences that matter are narrower than the brochures suggest. They are about the room, not the brand.

Daikin and Mitsubishi Electric are equally good choices for a London home. Both flagship wall units reach 19 dB(A) on their lowest fan speed, and a single room costs 2,400 to 3,200 pounds fitted with either, because the unit is the smaller half of an installed price.

Choose Daikin for heating efficiency and a slim unit over a door. Choose Mitsubishi Electric for the value of the MSZ-AP and the larger multi-split outdoor range.

What Daikin is genuinely better at

Heating. The Perfera's A+++ rating and SCOP of up to 5.1 matter from October to April, when a well-chosen air conditioner is the cheapest heat in the house per kilowatt and most people never switch it on because they think of it as a cooling machine.

A slim unit where depth matters. The Stylish is 189mm deep, which counts above a door or on a wall people walk close to, and it comes in four finishes including wood.

Mixing ranges on one system. A Stylish in the living room and a Sensira in the spare room can share one MXM outdoor unit, so the money goes where somebody will notice it.

Two of our own Daikin quotations from 2026, with no customer detail: three rooms on Daikin Stylish at £8,391 and five rooms on Daikin Perfera at £11,332, both fitted and including VAT. More on the Daikin page.

What Mitsubishi Electric is genuinely better at

Value without a visible compromise. The MSZ-AP uses the same compressor technology and the same controls as the range above it, and in most rooms nobody can tell it from the flagship. It is the unit we fit most often of any brand.

Whole houses from one outdoor position. The MXZ multi-split outdoor units run up to eight indoor units, against five on Daikin's MXM. On a London terrace with exactly one sensible place for an outdoor unit, that can decide it.

Scheduling that people actually use. MELCloud lets a system start at low output an hour before you need it, which costs less to run than asking it to pull a hot room down in ten minutes. More on the Mitsubishi Electric page.

Why the installation matters more than the badge

Across both brands the indoor unit is a minority of the installed price. The rest is the pipe run, the core drilling, the electrical work, the outdoor position and the commissioning, and none of that changes with the name on the front.

It is also what decides how long the system lasts. A weighed refrigerant charge, a real pressure test and a proper vacuum do more for year ten than the choice between two manufacturers who are both among the best in the world.

And the noise a neighbour hears comes from the outdoor unit, where a domestic Daikin and a domestic Mitsubishi sit in the same 46 to 52 dB(A) band at one metre. Position and anti-vibration mounts do more than the badge. See the noise page.

Other things people weigh up

Split vs portable air conditioning

A portable unit costs 300 pounds and a fitted split costs 2,400.

Compare

Single split vs multi-split

If you want more than one room cooled, this is the decision that shapes the whole installation: several small outdoor units, or one bigger one serving all of them.

Compare

Air conditioning vs air source heat pump

These are the same technology wearing two names, and the confusion costs people real money.

Compare

Ceiling cassette air conditioning

A cassette sits flush in the ceiling and sends the air out across the room from above, so nothing goes on the wall.

Compare

Ducted air conditioning hidden from view

With a ducted system the indoor unit sits out of sight in a ceiling void, a loft or a cupboard, and the air reaches the room through ducts and grilles.

Compare

What happens on a survey

An hour, nothing to sign, and a written fixed price afterwards. The fastest way to settle any of this properly.

Questions people ask

Which is quieter, Daikin or Mitsubishi Electric?

Indoors, neither: the Daikin Perfera and Stylish and the Mitsubishi MSZ-LN all reach 19 dB(A) on their lowest fan speed, which is below a quiet bedroom at night.

Outdoors, they sit in the same band too. The position of the outdoor unit decides more than the brand.

Which is more reliable?

Both are among the most reliable makes there are, with deep UK spare parts networks. The faults we are called out to are far more often about how a system was installed than about which of these two brands it is.

Whichever you choose, the manufacturer warranty is registered in your name.

Is Mitsubishi Electric the same as Mitsubishi Heavy Industries?

No. They are separate companies that both make air conditioning, and their ranges are not interchangeable. This page is about Mitsubishi Electric, the MSZ and MXZ ranges. We install Mitsubishi Heavy Industries equipment as well.

Which would you fit in a bedroom?

For a light sleeper, either flagship: the Daikin Perfera or the Mitsubishi MSZ-LN. For everybody else the Mitsubishi MSZ-AP or a Daikin Sensira does the same job for less.

The bedroom page covers the sizing, which matters more than the brand.
