What is a multisplit system?

A multisplit system connects several indoor units to a single outdoor unit, also called the compressor. Instead of installing a separate air conditioner for each room, you build one system that serves two, three, four or five spaces. It is the perfect solution when you want to cool the whole house while leaving just one outdoor unit outside, reducing clutter on the balcony and the visual impact on the façade.

How to build a multisplit, step by step

Building a system is simple if you follow a precise order. In our catalogue you will find 578 products between outdoor units and indoor units, all ready to ship.

  • Count the rooms to be cooled: each room will have its own indoor unit.
  • Choose the BTU of each indoor unit based on the square metres of the room, from 5000 BTU for small spaces up to 24000 BTU for the largest areas.
  • Add up the required capacities and choose an outdoor unit able to power them all.
  • Check the number of connections on the outdoor unit: a dual handles 2 units, a trial 3, a quadri 4, a penta up to 5.

If instead you only need to cool a single room, consider a wall-mounted monosplit air conditioner.

From 2 to 5 indoor units: dual, trial, quadri and penta

The most common configurations start at two units and go up to five. Choose the one that suits your home:

  • Wall-mounted dual split, one outdoor unit and 2 indoor units, ideal for the bedroom and living room.
  • Wall-mounted trial split, one outdoor unit and 3 indoor units, perfect for a medium-sized apartment.
  • Wall-mounted quadri split, one outdoor unit and 4 indoor units, designed for the whole house.
  • Penta split, one outdoor unit and 5 indoor units, for villas and homes with many rooms.

How to choose the outdoor unit

The outdoor unit is the heart of the system and must be sized on the sum of the indoor units. The available capacity ranges from 5000 up to 60000 BTU, so you cover both small apartments and larger floor areas. Good sizing leaves a small margin, because rarely do all the units work at full capacity at the same time. If you want to see all the available outdoor units, check the outdoor units section.

The indoor unit combinations

The strength of the multisplit is the freedom to combine units of different sizes. You can pair a 9000 BTU unit for the bedroom, a 12000 BTU unit for the living room and a 7000 BTU unit for the study, all connected to the same outdoor unit. The most requested sizes in our catalogue are 9000 BTU with 106 models and 12000 BTU with 111 models, followed by 18000 BTU for large rooms. You can also choose different types, such as wall units and cassette units recessed into the ceiling.

The advantages of the multisplit

A multisplit system brings concrete benefits compared with many separate air conditioners:

  • A single outdoor unit, so less clutter and a tidier façade.
  • Independent management of each room, with different temperatures in each space.
  • Inverter heat pump technology to cool in summer and heat in winter.
  • Option to add smartphone control with the smart models compatible with Alexa and Google Home.

The best brands for your multisplit

Build the system with the most reliable manufacturers, with official warranty and available spare parts: Daikin with 88 models, Mitsubishi Electric with 83 models, Haier, Hisense, Midea, Samsung, Fujitsu and Panasonic. Prices start at around 79 euros for individual units and reach the most high-performing complete solutions. You will find plenty of promotions in the offers section.

Frequently asked questions

How many indoor units can I connect to a single outdoor unit?
It depends on the number of connections on the outdoor unit: a dual handles 2, a trial 3, a quadri 4 and a penta up to 5. Choose the outdoor unit based on the number of rooms you want to cool.
How do I choose the capacity of the outdoor unit?
Add up the BTU of all the indoor units you want to connect and choose an outdoor unit able to power them, leaving a small margin because rarely do they all work together at full capacity. The available capacities range from 5000 to 60000 BTU.
Can I combine indoor units with different capacities?
Yes, that is precisely the advantage of the multisplit. You can pair a 9000 BTU unit for the bedroom, a 12000 BTU unit for the living room and a 7000 BTU unit for the study, all connected to the same outdoor unit.
What is the difference between dual, trial and quadri split?
Only the number of indoor units connected to the outdoor unit changes: the dual has 2, the trial 3 and the quadri 4. The operating logic stays the same, with a single outdoor unit serving all the rooms.
Is a multisplit better than many separate monosplit units?
The multisplit is worthwhile when you want to cool several rooms while leaving just one outdoor unit outside, with less clutter and a tidier façade. Separate monosplit units remain handy when the spaces are very far apart from one another.
Can I combine wall and cassette units in the same system?
Yes, many outdoor units allow you to connect different types of indoor units, such as wall units and cassette units recessed into the ceiling. It is best to check the compatibility of the chosen outdoor unit before building the system.
