Common questions
Yes. The Swiss tenants' association confirms it: mobile air conditioning units are allowed without the landlord's consent as long as no structural changes are made. Our units are built exactly for this: no drilling, no facade mounting, and they move out with you.
Indoors, far quieter than any monobloc, because the heat exchanger works outside. In silent mode the indoor units measure 38 to 39 dB(A), about as loud as rustling leaves. At full power it is around 49 to 51 dB(A). The outdoor unit reaches 56 to 61 dB(A): for night use, avoid placing it right outside your neighbour's bedroom window.
Much less than most people think. Thanks to the inverter and split principle (SEER 5.6 to 6.1), the units draw 300 to 600 watts on average while cooling. At 30 centimes per kWh, an hour of cooling costs about 10 to 20 centimes, a full night about 1 to 1.50 francs. A typical monobloc uses more than double for the same effect. In heating mode, 1 kWh of electricity delivers about 4 kWh of heat.
