Split air conditioning: what it is, how it works, and why it could be perfect for your home
Are you thinking of improving climate control in your home? Discover what a split air conditioner is, how it works, and whether or not it is the ideal option for your home.
If you're considering improving climate control in your home, you've probably come across the term split air conditioning. But what exactly is it? How does it work? Does it suit what you're looking for in your home? In this article, we're going to clear up everything you need to know about this system, from the basics to its most innovative applications. All with a practical, clear approach, allowing you to make informed decisions about comfort in your home.
What is split air conditioning?
Imagine a quiet, efficient, and elegant climate-control system that you barely notice but which completely transforms the atmosphere in your home; in other words, split air conditioning. The term 'split' precisely describes what it does: it splits the system into two main units.
An indoor unit, which is installed inside the home and is responsible for cooling (or heating) the air you breathe.
An outdoor unit, which is located on the outside of the building and performs the more intense technical work: compressing the refrigerant gas and expelling the heat.
Both are connected by discreet pipes that allow the system to operate in a closed loop. The result? The ideal temperature throughout your home, optimised energy use, and improvements to your décor when choosing the right model.
This type of system has become a firm favourite for climate control in homes and offices. Why? Thanks to its efficiency, low noise level, and versatility. But let's not get ahead of ourselves... read on and we'll tell you everything you need to know to make an informed decision.
How does a split air conditioner work?
The operation of a split air conditioner may seem complex, but it's easy to understand if we break it down step by step.
Indoor air intake: the indoor unit draws in the warm ambient air.
Heat transfer: the refrigerant gas circulating through the internal circuit absorbs this heat and carries it to the outdoor unit.
Heat expulsion to the outside: in the outdoor unit, the compressor compresses the gas and releases it as heat into the outdoor environment.
Continuous cycle: the gas, now colder, returns to the indoor unit to repeat the cycle, cooling and directing the air back into the room.
When the system operates as a heat pump in winter, this process is reversed: heat is captured from the outdoor air (yes, even when it's cold) and transferred into the home.
This thermal exchange process is highly efficient and maintains a comfortable year-round temperature with moderate energy use, particularly when using an inverter system.
Types of split air conditioning
While we often refer to "split air conditioners", there are actually various types within this category, each tailored to different home needs and styles.
1. 1x1 split system
This is the most common system in homes: an indoor unit and an outdoor unit. It is designed for climate control in a single room, making it ideal for providing comfort in specific areas like the bedroom or living room.
2. Multisplit system
Multisplit systems allow several indoor units (two, three, four or more) to be connected to a single outdoor unit. It is a very practical solution for climate control in several rooms without having to install a compressor for each one. Moreover, each indoor unit can be controlled independently to customise the climate in each room.
Why choose a Daikin split system?
Now that you know what a split air conditioner is and the different types available, the most important question is: why choose Daikin?
The short answer would be for its efficiency, reliability, and technology. But let's delve a little deeper.
1. Inverter technology: pure energy efficiency
Most Daikin systems use Inverter technology, allowing the compressor to modulate its power to maintain a stable temperature and reduce energy consumption, rather than constantly switching on and off. This results in lower electricity bills and increased durability for your equipment.

2. Absolute silence (or almost)
Daikin's split systems are designed to offer a very low sound level in both the indoor and outdoor units. Some models reach barely 19 dB(A), which is quieter than a library.
3. Discreet, elegant design
Aesthetics also matter, and Daikin split systems have evolved a lot in this regard. Models such as the Stylish or the Emura combine minimalist lines, modern colours, and high-quality materials that easily integrate into any home décor.
4. Smart control from your mobile device
With the Daikin Onecta app, you can control your split system from your smartphone: switch it on, switch it off, programme schedules, adjust the temperature, or check energy consumption. Everything at your fingertips.
5. Air quality: much more than cooling or heating
Daikin goes beyond climate control. Many of its models incorporate advanced purification filters, such as the Flash Streamer filter, which eliminates pollutant particles, viruses, bacteria and odours from the air. Ideal if you live with allergy sufferers, small children, or simply want to breathe better at home.
What maintenance does a split air conditioner require?
One of the strengths of the split system is its straightforward maintenance. Even so, it is worth bearing in mind some basic tasks to prolong its lifespan and ensure optimal performance:
Clean the filters: every two to three weeks, particularly during peak usage months. A clean filter improves air quality and reduces consumption.
Annual technical check-up: it is recommended to check the condition of the refrigerant gas, the pressure, and compressor performance.
Check the outdoor unit: it is important to keep it free of obstacles, leaves, or dirt that might interfere with heat exchange.
For Daikin systems, official technical services ensure maintenance with warranties and original parts, protecting your investment.
Plus, by registering your split air conditioner with Stand By Me (Daikin's after-sales service) upon purchase, you can receive priority attention, an extended warranty, and additional benefits.
Is it a suitable system for every home?
The answer is yes, with some caveats. Split systems adapt very well to flats, detached houses, offices, or even small shops. However, some factors need to be considered:
Climate control requirements: if you only need to cool one room, a 1x1 systems is sufficient. If you are looking for climate control for the whole property, a multisplit or ducted system might be more suitable.
Space for the outdoor unit: an accessible place (terrace, patio, outside wall) is needed to install the compressor.
Type of property: in buildings with strict community regulations, permission may need to be requested to install the outdoor unit.
In any case, it is always advisable to consult a professional installer to study your case and advise you on the best solution.
In short…
Now that you understand what a split air conditioner is, how it works, the different types available, and the benefits of Daikin models, you're sure to have a much clearer idea of how to choose your next air conditioner.
Comfort, energy efficiency, design, quietness, and better air quality: Daikin split systems have it all to make your home a place where you always want to be, whatever the weather outside.
