Multi-split AC — one outdoor unit, your whole home under control.

A multi-split AC system is an air conditioning system where one outdoor unit serves two or more indoor units. Each indoor unit has its own remote control and can be independently set to cooling or heating mode.

This allows you to air condition an entire apartment or house with one system — without needing multiple outdoor units on the facade.

The price of a multi-split AC with installation in Croatia varies by configuration and brand:

Dual (1+2): from €1,500 including all materials and labour
Trial (1+3): from €2,100
Quadri (1+4): from €2,900
Penta (1+5): from €3,600

Our packages start from €1,036 (unit only), with installation from €500 for dual to €1,100 for penta. Premium brands (Daikin, Mitsubishi) go up to €4,500–5,000 installed.

Mono-split has one outdoor and one indoor unit — it air conditions one room.

Multi-split has one outdoor and 2 to 5 indoor units — it air conditions multiple rooms.

Multi-split saves facade space, looks cleaner and requires fewer wall penetrations, but has a higher initial cost. If the outdoor unit fails, all indoor units stop working — a risk that does not exist with mono-split.

The most common configurations are: dual (1+2), trial (1+3), quadri (1+4) and penta (1+5). Some manufacturers support up to 8 indoor units, but for residential use 5 is a realistic maximum.

If you need to connect more than 5 units (commercial building, hotel, large house), it is better to consider a VRV system.

Basic rule: 1 kW of AC capacity ≈ 10 m² of space. For a 20 m² room a 2.5 kW indoor unit is sufficient; for a 30–40 m² living room you need 3.5–4.2 kW; for 50 m² you need 5 kW.

The outdoor unit capacity must cover the sum of all indoor unit capacities (with a small reserve since they rarely all run at full power simultaneously).

For a precise calculation we provide a free thermal load and cooling load analysis — taking into account orientation, glazing, insulation and the climate conditions at your location.

Modern multi-split systems with inverter technology and R32 refrigerant are classified as A+++, meaning very low power consumption.

When only one indoor unit is running, consumption is about 20–30% higher than an equivalent mono-split AC. However, when 2 or more units run simultaneously, multi-split saves electricity because one inverter compressor serves all indoor units.

Standard installation includes: one wall penetration (brick up to 50 cm, concrete up to 30 cm), up to 3 m of pre-insulated copper pipes per unit, PVC trunking, outdoor unit brackets, condensate drain pipe, electrical connection, all consumables, system evacuation (vacuum), commissioning and user training.

Prices: dual €500, trial €700, quadri €900, penta €1,100.

Yes — we operate across all of Croatia. Delivery is free for all of continental Croatia (islands by arrangement).

Our office is in Zagreb (Ulica Zlatarova Zlata 16), and we regularly install in Split, Rijeka, Osijek, Zadar, Slavonski Brod, Karlovac, Sisak, Varaždin, Pula, Šibenik and other cities.

Yes — for an average apartment or well-insulated house, an inverter AC with SCOP 4–5 is currently the most cost-effective way to heat. From 1 kWh of electricity you get 3–5 kWh of heat (the rest comes free from outdoor air).

At the HEP blue tariff, one hour of AC running at 3.5 kW costs approximately €0.12–0.15 — cheaper than gas, heating oil and pellets. The investment in a dual or trial multi-split heating system pays back within 3–5 heating seasons.

Important: for heating as the primary function, choose models with outdoor unit heaters and an operating range of at least –15 °C.

These are ACs where the manufacturer has built small electric heaters at 3 points into the outdoor unit: the base plate (prevents ice in the bottom), the compressor crankcase (keeps oil fluid) and the heat exchanger (faster defrost).

Result: the AC reliably heats even when outside temperatures drop to –15 °C to –25 °C, without loss of efficiency. Without these heaters an AC at –10 °C uses 2× more electricity and is prone to freezing damage.

Recommendation: if you are heating continental Croatia (Zagreb, Slavonia, Lika, Gorski kotar) — you must have an AC with outdoor unit heaters. For the coast (Dalmatia, Istria, Kvarner) and mild winters, a standard model is sufficient.

Budget models (from ~€700): Maxon, Airwell, Hyundai, Korel. SCOP 3.8–4.1. Reliable heating to about –7 to –15 °C. Ideal for the coast or as a supplement to existing heating.

Mid-range (~€1,000): LG, Haier, Midea, Fuji. SCOP 4.2–4.6. Heating to –15 °C, most have base plate and crankcase heaters. Best price-to-savings ratio for year-round heating.

Premium (~€1,500+): Daikin Perfera, Mitsubishi Zubadan, Panasonic Heatcharge, Samsung WindFree. SCOP 4.8–5.1, heating to –25 °C with full capacity at –15 °C. The right choice when the AC is the main heat source for the home.

We work with over 15 brands, from premium to budget:

Premium: Daikin, Mitsubishi Electric, Toshiba, Samsung, LG, Panasonic, Bosch.
Mid-range: Haier, Hisense, Gree, Midea, Korel, Feroterm/Terma Air.
Budget: Maxon, Azuri.

All systems we offer use eco-friendly R32 refrigerant and inverter technology.

Product warranty: 2–5 years depending on manufacturer. Daikin offers free extension to 5 years through their Stand-By-Me portal.

Installation warranty: 24 months in writing.

All servicing and refrigerant top-ups are carried out by our F-gas certified technicians.

Yes — this is one of the key advantages of multi-split. You can connect to the same outdoor unit:

• Wall-mounted units (most common for residential)
• Cassette units into a suspended ceiling (offices, living rooms)
• Floor-standing units (where there is no wall space)
• Ducted units (concealed distribution)

Each must be compatible with the chosen outdoor unit — we help you design a consistent and functional system.

R32 is an eco-friendly refrigerant that became the industry standard in 2026. Three key advantages:

• Lower environmental impact — GWP (Global Warming Potential) three times lower than the old R410A
• Higher efficiency — better heat transfer coefficient
• Smaller charge — the system uses about 20% less refrigerant for the same output

All our multi-split systems use R32.

For heating as the primary heat source in continental Croatia we recommend:

Daikin Perfera (FTXM/3MXM series) — SCOP up to 5.1, reliable heating to –25 °C, the industry reference. daikinkli.me

Mitsubishi Electric Zubadan — patented Zubadan technology, full capacity at –15 °C, operating range to –25 °C. mitsubishi.com.hr

Vaillant VAF 8 — German quality, SCOP up to 4.8, 5-year warranty, excellent option for cold climates. vaillant.com.hr

Panasonic Heatcharge (CU-Z series) — SCOP up to 5.0, VZ Heatcharge indoor series. panasonickli.me

For milder coastal winters, LG, Bosch or Vivax with SCOP 4.2–4.5 are also sufficient.

Daikin Multi+ (2/3/4/5MXM series):

• Price: €1,737 (Dual 4 kW) to €4,250 (Penta 9 kW)
• Warranty: 5 years through Stand-By-Me registration
• Special: Bluevolution R32, heating to –25 °C with Perfera indoor units, SCOP up to 5.1
• Indoor options: Sensira, Comfora, Perfera, Emura, Stylish (each a separate line with its own specs)

LG Multi Split (MU2R/MU3R/MU4R/MU5R series):

• Price: €1,413 (Dual 4.1 kW) to €1,795 (Penta 8.8 kW) — significantly more affordable
• Warranty: 2 years standard
• Special: excellent for combined heating and cooling, SCOP 4.3–4.6
• Indoor options: Artcool Mirror, Standard Plus, cassette

Conclusion: LG is 30–50% cheaper with solid performance. Daikin is worth it for demanding heating in cold weather — the difference is noticeable below –10 °C.

A 60 m² apartment typically requires a Dual or Trial configuration — one living room and 1–2 bedrooms:

Budget option — Bosch CL5000M 41 Dual (4.1 kW): €920 (outdoor) + indoor units + installation ~€500 = total ~€1,700–2,000

Mid-range — Vivax COFM-28 AERI Dual (5.3 kW): €920 + installation = ~€1,800

Premium — Daikin 3MXM52A9 Trial (5.2 kW): €2,275 + indoor units + installation €700 = ~€3,500–4,000

For cooling only a 60 m² apartment on the Dalmatian coast, a Dual (2+1) is sufficient — for continental Croatia and heating as the primary source we recommend Trial (3+1) to cover each room with its own unit.

Yes — for continental Croatia (Zagreb, Slavonia, Lika, Gorski kotar) where temperatures fall to –15 °C and below, we offer specialist models:

Daikin Multi+ with Perfera indoor units — standard heating to –25 °C without capacity reduction. Base plate, crankcase and heat exchanger heaters built in. daikinkli.me

Mitsubishi Electric Zubadan — unique Zubadan compressor that heats at full capacity at –15 °C, operating range to –25 °C. mitsubishi.com.hr

Vaillant VAF 8 — designed for cold climates, heating to –20 °C. vaillant.com.hr

At temperatures below –10 °C standard models without outdoor unit heaters are not adequate — they use 2× more electricity and are prone to freezing failures.
