A true split: the compressor lives outside — no drilling, no building work, no permission needed
You've bought a portable air conditioner before. It was loud, you had to empty the tank, and hot air came straight back in through the badly sealed window. It's in the cellar now. The DuoSplit™ is not a portable air conditioner. It's a genuine two-block split system: the compressor lives outside, not in your bedroom. Everything else follows from that.
Because the noise, the heat and the water all stay outside — and you don't need anyone's permission to install it.
Maintenance: clean the indoor unit's filter in lukewarm water every two to three weeks during peak season. That's all the appliance asks of you.
There is nothing to refuse: no drilling, no permanent fixings, no changes to the outside of the building. The outdoor unit sits on a window ledge, a balcony or a terrace, and the connecting line runs through the sealing kit supplied. It comes down as quickly as it goes up — you can take the whole thing away in minutes before a check-out inspection. That is precisely why the DuoSplit™ exists: to get a proper split system when you are not allowed to have one fitted.
Yes. The sealing kit supplied fits the most common window types, tilt-and-turn and sliding included. The connecting line is only 6 cm wide: it passes through the opening without forcing and without damaging the seal. On a double-casement window, add the foam strip to the second leaf to close off the airflow completely.
On a ledge, a balcony or a terrace: it measures 43.8 × 50 × 26 cm and weighs under 6 kg, so you can position it on your own. The security cable and protection plate are included in the box — you strap it to the railing in two minutes and it can neither slip nor be lifted off. If you are away for a few days, it comes back in as easily as it went out.
39 dB is the level of a quiet room at night, well below a whispered conversation. The reason is simple: the compressor — the noisy part of any air conditioner — is outside. All that is left in the bedroom is the sound of air moving over the indoor unit. That is the whole difference with a portable monobloc, which puts the motor at the foot of your bed.
Around €0.50 a day for 10 hours of use, measured at 1.37 kWh over 6 hours. The DuoSplit™ is rated SEER 20, A++ for cooling, and uses R32 refrigerant. The exact figure depends on your insulation, the floor area you are cooling and your electricity tariff — but the order of magnitude is that of a powerful fan, not a heater.
Orders are picked within 1 to 2 working days, then dispatched. Both units, the insulated connecting line and the complete window sealing kit travel in a single parcel. A tracking link is emailed to you as soon as it ships.
30 days to change your mind. The unit must come back complete and in its original packaging — keep the box while you put it through its paces. Get in touch before sending anything back and we’ll talk you through it.
Fiabelo warranty: if you find a manufacturing fault on arrival, contact us within 30 days — exchange or refund depending on the case. The refrigerant circuit is sealed at the factory and needs no re-gassing and no engineer.
As seen in
A monobloc puts the compressor in your bedroom, draws in your indoor air to blow it outside, and creates negative pressure that pulls hot air back in through seals and doors. The DuoSplit™ is a true two-unit split: 12,000 BTU, 3.5 kW, up to 45 m² — and the noise, the heat and the water stay outside.
The sealing kit is included, it plugs into a normal socket, and nothing is permanently fixed to the building. Renting, in a managed block, tilt-and-turn or sliding window: fitting takes a few minutes and removing it takes just as long. The outdoor unit measures 43.8 × 50 × 26 cm and weighs under 6 kg — you can put it on a ledge, a balcony or a terrace on your own.
With the compressor outside, all that is left in the room is the sound of air: 39 dB in Silent mode, the level of a quiet room at night. There is no tank to empty either — condensate runs out through the line to the outdoor unit. And in the shoulder seasons the reversible heat pump warms the room, so the unit doesn’t sit in a cupboard for eleven months of the year.
