Ductless Air Conditioners

Whether you are sweating through an unexpected British heatwave or trying to maintain a comfortable working environment in a London office, finding the right air conditioner is more important than ever. The UK climate is changing, and summers are becoming increasingly hot and unpredictable. As a result, demand for quality Air Conditioning Units, ductless mini split air conditioners, and professional air conditioning service has never been higher.

At ACL London, we have been helping homeowners, landlords, and businesses across the capital find, install, and maintain the perfect AC unit for their needs. Whether you are searching for ac repair near me, looking to invest in a new air conditioner, or simply exploring your options for mini split ac systems, this comprehensive guide covers everything you need to know — from ac unit cost to choosing the best brands and understanding air conditioner installation processes in the UK.

This guide is designed to walk you through every aspect of residential and commercial air conditioning in the UK, with all costs quoted in £ sterling. Let us begin.

Chapter 1: What Is an Air Conditioner? A UK Guide

An air conditioner — commonly referred to as an AC, aircon, or air con unit — is a system designed to regulate the temperature, humidity, and overall air quality of an indoor space. In the UK, air conditioning units are used in homes, offices, retail spaces, schools, and industrial environments. The primary function of an AC unit is to remove heat from an indoor space and expel it outside, leaving the interior cool and comfortable.

Modern home air conditioner systems do far more than just cool a room. Many of today’s systems double as heating and air conditioning units, providing year-round climate control. A reverse cycle air conditioner, for example, can both cool in summer and heat in winter — making it an incredibly versatile and cost-effective solution for UK properties.

The basic components of a standard air conditioning unit include:

A compressor — pressurises the refrigerant (also known as ac freon) to enable heat exchange
A condenser coil (located in the outdoor ac unit) — releases heat outside
An evaporator coil (located in the indoor ac unit) — absorbs heat from inside
An air conditioning fan — circulates air across the coils
An ac duct system (in ducted systems) — distributes conditioned air throughout the property
A thermostat or control panel — regulates temperature and settings

Understanding how your hvac air conditioner system works is the first step to making an informed purchase or repair decision. If you ever notice your ac not cooling properly, or your ac unit not cooling as expected, it is likely one of these core components needs attention from a qualified ac repairman or ac specialist.

At ACL London, our team of certified engineers provides expert air conditioner repair, ac servicing, and full Ac Unit Installation services across London and the surrounding areas. If you are looking for an ac company near me, look no further.

Chapter 2: Types of Air Conditioning Units Available in the UK

The UK market offers a wide variety of air conditioning units to suit different property types, budgets, and requirements. Understanding the differences between each type will help you choose the most appropriate system. Below, we explore all the major types of AC systems available in Britain today.

2.1 Split System Air Conditioners

The split air conditioner — also referred to as a split system air conditioner, split ac unit, or split unit air conditioner — is by far the most popular type of air conditioning system installed in UK homes and offices. It consists of two main components: an indoor ac unit mounted on the wall and an outdoor air conditioner unit fixed to the exterior of the building.

A split ac system is quiet, efficient, and aesthetically pleasing. The Wall Mounted Air Conditioner sits neatly on the wall without the need for any ductwork, making aircon installation relatively straightforward compared to ducted alternatives. These are also known as wall air conditioning units or wall mounted ac units.

The split ac unit cost in the UK typically ranges from approximately £500 to £2,500 for the unit alone, with split ac installation cost adding a further £300 to £800 depending on the complexity of the job. ACL London offers competitive pricing on all split air conditioner installation projects across the capital.

Popular split ac models in the UK include systems from Mitsubishi, Daikin, Fujitsu, Toshiba, LG, Samsung, and Panasonic — all of which are available through ACL London.

2.2 Ducted Air Conditioning Systems

Ducted air conditioning — sometimes called a ducted aircon or central air conditioning system (though in the UK we refer to it more commonly as a whole-house or full-building system) — distributes conditioned air throughout a property via a network of concealed ducts. This type of system is ideal for larger homes, commercial buildings, and new-build properties in London where discreet installation is a priority.

The ducted air conditioning cost in the UK is considerably higher than a standard split system, typically ranging from £3,000 to £10,000+ depending on the size of the property and complexity of the ductwork. Ducted air conditioning price also varies based on the brand chosen — systems from Daikin, Mitsubishi, and Fujitsu tend to command a premium due to their superior reliability and efficiency.

Ducted reverse cycle air conditioning is a particularly popular choice for properties that require both heating and cooling throughout the year, as these systems can operate efficiently in both modes. The ac duct repair and maintenance of these systems is best left to qualified professionals, such as the team at ACL London.

Daikin ducted air conditioning systems are amongst the most sought-after in the UK, renowned for their reliability, energy efficiency, and whisper-quiet operation. If you are considering a ducted installation, searching for air conditioning contractors near me or ac contractors near me is a good starting point — and ACL London serves the entire Greater London area.

2.3 Wall Mounted Air Conditioners

A wall mounted ac unit or wall air conditioner is one of the most common types of air conditioning unit found in UK homes and offices. These units are permanently installed into or onto the wall of a room, providing dedicated cooling or heating for that specific space.

A wall ac unit can be a single split system or part of a larger multi split air conditioner setup. They are an excellent choice as a bedroom air conditioner, air conditioning unit for bedroom, or air con unit for bedroom, as they are typically very quiet and can be controlled via remote or smartphone app.

A wall ac unit differs from a through the wall air conditioner, which is inserted directly through a hole in an exterior wall rather than being surface-mounted. A through the wall air conditioner with heat option is also available, making it a practical air conditioner heater combo for year-round use.

A heater air conditioner combo wall unit is an especially popular choice in London properties where space is at a premium and a single, discreet unit is preferable to separate heating and cooling appliances. A wall air conditioner and heater combined unit from brands like Mitsubishi or Daikin typically costs between £800 and £2,000 including installation.

2.4 Portable & Personal Air Conditioners

Not everyone can commit to a permanent installation. For those looking for a more flexible solution, a portable air conditioner — also known as a stand up air conditioner, stand up ac unit, vertical air conditioner, or stand up ac — offers a convenient and relatively affordable way to cool a single room without the need for professional installation.

Portable units are available from a wide range of manufacturers. The Dyson air conditioner range, including the distinctive Dyson aircon and dyson air con models, are popular premium options in the UK, known for their sleek design and multi-functionality. The Dyson air conditioning unit often combines cooling, heating, and air purification in a single device. Dyson aircon products are widely sold through major UK retailers.

Other popular portable options include the De’Longhi air conditioner (or pinguino air conditioner as their Pinguino range is known), the Meaco air conditioner, the Honeywell air conditioner, and the Black and Decker air conditioner. For budget-conscious shoppers, the Argos air conditioner range and various Amazon air conditioner listings offer affordable entry-level options.

A personal air conditioner or personal ac unit — sometimes called a mini ac cooler, mini ac, or tiny air conditioner — is a compact, desktop-sized device designed to cool a very small area immediately around the user. These are not true air conditioners but rather evaporative air conditioning devices or fans that cool like air conditioners. A neck air conditioner is a wearable variant designed for personal use on the go. While useful as a personal ac solution, these are not a substitute for a full air conditioning unit.

A windowless air conditioner or ventless air conditioner is another type of portable unit that does not require a window for venting. These are useful in rooms without accessible windows. The best windowless air conditioner options in the UK include models from De’Longhi, Honeywell, and Meaco. Similarly, a windowless ac unit is a popular search for renters or flat-dwellers in London who cannot make permanent alterations to their property.

A compact air conditioner, cube air conditioner, or small air conditioner is ideal for a single room air conditioner application, providing targeted cooling without the expense of a full system. These are often marketed as the best small air conditioner, best small room air conditioner, or small room air conditioner solutions, and prices start from as little as £100 to £400.

For outdoor or off-grid use, a camping air conditioner, camping ac, 12 v air conditioner, or 12 v ac unit provides a battery or vehicle-powered cooling solution. The Ecoflow air conditioner and Dometic air conditioner (or Dometic ac) are two of the most popular brands for this application, widely used in campervans, motorhomes, and outdoor events across the UK.

2.5 Multi-Split Air Conditioning Systems

A multi split air conditioner system connects multiple indoor wall mounted ac units to a single outdoor ac unit. This makes it ideal for larger homes or offices where several rooms need to be independently controlled from one external compressor. The multi split approach reduces the number of outside ac units on the building’s exterior, keeping the appearance clean and tidy.

Multi-split systems are available from all major brands including Mitsubishi, Daikin, Fujitsu, Toshiba, LG, and Samsung, and are commonly installed by ACL London in residential and light commercial properties throughout the capital. The ac system cost for a multi-split setup typically ranges from £2,000 to £8,000+ depending on the number of indoor units and brand selected.

Chapter 3: Ductless Mini Split Air Conditioners — A Complete UK Guide

One of the most exciting developments in modern UK air conditioning is the rise of the ductless mini split air conditioner — also referred to as a mini split ac, ductless ac, split ductless ac, ductless wall air conditioner, or simply a ductless mini split ac. These systems have become the go-to choice for homeowners and businesses across London and the UK who want efficient, flexible, and high-performance climate control without the disruption and cost of installing ductwork.

3.1 How Does a Ductless Mini Split Work?

A ductless air conditioner operates similarly to a standard split system but is designed to be even more compact and versatile. A mini split ac unit consists of one or more indoor ac units — typically wall-mounted — connected via refrigerant lines to an outdoor air conditioner unit. Because no ac duct system is required, ductless air conditioner installation is significantly less invasive and less expensive than ducted alternatives.

A mini split air conditioner installation typically involves mounting the indoor unit on the wall, running refrigerant pipework through a small hole in the wall to the outside ac unit, and connecting the electrical supply. A professional mini split ac installation from ACL London can usually be completed within a single day for a standard single-room setup.

The mini split ac system is available in both cooling-only and mini split ac and heat (reverse cycle) configurations. A mini split ac heat system can provide both cooling in summer and heating in winter, making it a truly year-round solution for UK properties. This type of split unit ac and heat system is often referred to as a heat pump in UK energy efficiency circles.

3.2 Benefits of Ductless Mini Split Air Conditioners

No ductwork required — ideal for older UK properties, period buildings, and flats where installing ducted aircon would be impractical or cost-prohibitive
Energy efficiency — inverter air conditioner technology used in most ductless ac units means they adjust their output to match the room’s requirements, reducing energy waste
Quiet operation — a quiet air conditioner is essential in bedrooms and offices; mini split systems are among the quietest available
Flexible installation — a mini ac unit can be installed in virtually any room, including lofts, extensions, and conservatories
Zone control — each mini split ac unit can be independently controlled, allowing different rooms to be set at different temperatures
Year-round comfort — with mini split ac and heat capability, one system replaces both your air conditioner and supplementary heating
Affordable ac running costs compared to traditional electric heating

3.3 Ductless Mini Split Cost in the UK

One of the most common questions we receive at ACL London is: “What is the ductless air conditioner cost?” The answer depends on a number of factors, including the brand, capacity (measured in BTUs or kW), number of indoor units, and the complexity of the installation.

Here is a general breakdown of ductless ac cost in the UK:

Entry-level ductless mini split (e.g., Midea ac, budget ac brands): £400 – £900 for the unit
Mid-range ductless mini split (e.g., LG air conditioner, Samsung air conditioner, Panasonic air conditioner): £800 – £1,800 for the unit
Premium ductless mini split (e.g., Mitsubishi ductless air conditioner, Daikin air conditioners, Fujitsu air conditioning, Toshiba): £1,200 – £3,500 for the unit
Mini split ac installation cost: typically £300 – £800 per indoor unit
Total mini split ac cost (unit + installation): £700 – £4,500 depending on specification

The mitsubishi ductless air conditioner cost is typically at the higher end of the scale, reflecting the brand’s exceptional build quality and long-term reliability. However, when you factor in lower running costs and the brand’s proven inverter aircon technology, the investment often pays for itself over time.

For those looking for mini split ac for sale or ac units for sale in the UK, ACL London offers competitive aircon prices across a wide range of brands and specifications. We also regularly run aircon specials and air conditioner deals throughout the year, so it is always worth checking with us for the latest ac price low price offers.
