Air conditioning has to sit somewhere in the room, and in a carefully designed interior that matters. The good news is that manufacturers have taken appearance seriously for years. Some wall-mounted ranges are designed as much for looks as for performance, with different finishes and shapes. And if you would rather see nothing at all, ducted and cassette systems hide most of the equipment.
This guide looks at the design-led options, the hidden ones, and the details that make any installation look neater. Model details below come from the manufacturers’ own UK sites.
Daikin Emura
Daikin describes the Emura as “an icon in contemporary climate control, designed to please the eye”. It is a wall-mounted unit with a distinctive curved shape, offered in white, silver or black finishes. Like other Daikin splits, it is an air-to-air heat pump, so it can heat as well as cool.
It suits rooms where the unit will be on show, such as living rooms with modern decor, and spaces where a dark finish works better than white against the wall colour. Our Daikin page covers the wider range, and Daikin’s standard warranty on split air conditioning is 2 years.
Mitsubishi Electric Zen
Mitsubishi Electric’s MSZ-EF Zen wall-mounted range is described in its UK product information as blending streamlined design with energy efficiency, with a choice of three colours: black, silver and white. It uses R32 refrigerant and offers Wi-Fi control.
The Zen has a slimmer, flatter look than a standard wall unit, which suits clean, minimal rooms. See our Mitsubishi Electric page for more on the brand. Model codes and finishes change from time to time, so we confirm the current version on your quote.
Other brands
Most of the brands we install, including Fujitsu, Panasonic, Toshiba, LG and Samsung, offer ranges that go beyond the plain white box, such as different finishes or slimmer profiles. Ranges change from year to year, so tell us what matters (colour, depth, shape, mirror finish or matt) and we will show you current models from the manufacturers’ UK sites. Our best air conditioning units guide is a good starting point.

Hidden and low-profile systems
- Ducted: the unit sits in a ceiling void, loft or bulkhead, and only slim grilles show. It is the most discreet option, best planned during a refurbishment. See ducted air conditioning.
- Cassette: only a flat grille shows in the ceiling. Some cassettes are designed to fit standard ceiling grids. See cassette air conditioning.
- Floor console: sits low, like a modern radiator, and some can be partly recessed into the wall.

The details that make it look right
A beautiful unit can still look poor if the installation is careless. On design-led jobs we pay attention to:
- Pipe routes. Where possible, pipes run straight through the wall behind the unit, or are hidden in walls, ceilings or cupboards during building work. Where trunking is needed, it is run neatly and can often be painted.
- Symmetry and position. Centring a unit over a doorway or window, or lining it up with other features, makes a big difference.
- Condensate. If gravity drainage isn’t possible, a pump can be hidden in a void; see condensate pumps.
- Controls. A wall controller, a remote or an app: choose one that suits the room. Our smart air conditioning guide has more.
- The outside. The outdoor unit should be positioned with the same care. See where to put the outdoor unit.
Cost
Design-led units usually cost more than a standard model of the same capacity, and hidden pipework can add labour. Our single room split range is £1,200–£2,200 + VAT. Where you want a particular design-led model or a concealed pipe route, we survey and give you a fixed-price quote for that exact unit and install.
Before you fall for a finish in a brochure, ask to see it in person or in real photos. Matt, silver and black finishes look different in daylight and under warm lighting, and the right choice often depends on the wall colour behind it.
Quick answers
What is the most stylish air conditioning unit?
It depends on your room. The Daikin Emura and Mitsubishi Electric Zen are two well-known design-led wall units, offered in several finishes. Ducted systems are the most hidden.
Do design units perform as well as standard ones?
Compare the manufacturer’s published capacity, efficiency and sound figures for the exact model, rather than assuming either way.
Can I paint an air conditioning unit to match my wall?
No. Painting can affect airflow and warranty. Choose a finish the manufacturer offers instead. Trunking can often be painted.
Can the pipes be hidden?
Often, yes, especially during building work. Where they can’t, neat trunking keeps the run tidy.
