Loading…Multi split air conditioner
A multi split air conditioner is used to cool and heat multiple rooms separately with one outdoor unit. Each room has its own indoor unit, allowing living rooms, bedrooms, offices or workspaces to be controlled individually.
At Hewa, you will find multi split air conditioning combinations for homes, offices, retail spaces and project-based installations. When selecting the right system, check total capacity, number of indoor units, pipe lengths, height difference, BTU capacity, sound level, mounting position and the permitted combination between indoor units and outdoor unit.

Selecting a multi split air conditioner
A multi split air conditioner is suitable when several rooms need to be cooled or heated separately with one outdoor unit. Instead of installing a separate outdoor unit for each room, several indoor units are connected to one multi split outdoor unit. This keeps the outdoor installation clearer while still allowing room-by-room control.
Multi split air conditioners are often used in homes, apartments, offices, retail spaces, practice rooms and project-based installations. For installations with one room, single split air conditioning is more relevant. Also review air conditioner outdoor units when assessing separate outdoor units or technical combinations.
Important when choosing multi split air conditioners
- Check how many indoor units may be connected to the outdoor unit
- Match total capacity to room volume, heat load and simultaneous use
- Check BTU capacity and intended room application for each indoor unit
- Check maximum pipe length, total pipe length and maximum height difference
- Check permitted combinations between indoor units and outdoor unit
- Allow for condensate drainage, electrical connection, sound level and service access
- Have refrigerant work carried out by a qualified F-gas technician
Multiple indoor units on one outdoor unit
The main difference compared with a single split air conditioner is that a multi split system can operate several indoor units via one outdoor unit. Each indoor unit serves its own room, allowing different zones to be controlled separately. This is useful when, for example, a living room, bedroom and office each require their own comfort setting.
When selecting the right system, the technical combination options must be checked carefully. Not every indoor unit can be combined freely with every outdoor unit. The total capacity of the connected indoor units, the available outdoor unit capacity, pipe lengths and simultaneous heating or cooling demand determine whether the combination will operate reliably.
Frequently asked questions about multi split air conditioners
What is a multi split air conditioner?
A multi split air conditioner is an air conditioning system where several indoor units are connected to one outdoor unit. This allows multiple rooms to be cooled or heated separately.
When should I choose a multi split air conditioner?
A multi split air conditioner is suitable when several rooms need individual control and you do not want to install a separate outdoor unit for each room.
How many indoor units can I connect?
This depends on the outdoor unit type, total capacity, permitted combinations and technical specifications of the system. Always check the documentation of the outdoor unit.
What is the difference compared with single split?
A single split air conditioner has one indoor unit and one outdoor unit for one room. A multi split air conditioner has one outdoor unit to which several indoor units for multiple rooms are connected.
What should an installer check during installation?
Check total capacity, pipe lengths, height difference, refrigerant charge, condensate drainage, outdoor unit position, electrical connection, sound level, permitted combinations and technical documentation.
