Discreet reversible air conditioning, efficient all year

Yes. Reversible AC is an air-to-air heat pump: it heats efficiently for most of the winter when correctly sized for the room and insulation. Output drops in very cold weather, which we factor in during the survey. It does not produce domestic hot water.

Reversible AC heats and cools the air room by room, without producing hot water. An air-to-water heat pump feeds radiators or underfloor heating and can produce hot water, but does not always cool. Grants differ too: only air-to-water can get MaPrimeRénov'. Our guide compares both in detail.

It depends on how many rooms you want to treat, their size and the layout. In practice it is often one unit per living room or bedroom, connected to one or more outdoor units (multi-split), or a ducted system that distributes air through vents. The survey sets the exact number.

Single-split suits one room: one indoor unit linked to one outdoor unit. Multi-split connects several indoor units to a single outdoor unit, handy for several rooms with only one unit outside. The choice depends on the number of rooms, pipe distances and available space.

Yes, it is recommended. You clean the indoor unit filters regularly; once a year a professional checks circuit tightness, coils, condensate drainage and performance. A leak check is mandatory above a certain refrigerant quantity. Cofany offers annual servicing.

Sometimes. A prior declaration may be required depending on the commune and how visible the unit is, and the building's co-owners often need to agree in flats. The unit must also respect neighbourhood noise rules. We explain the steps during the visit.

Not much, with a recent, well-installed unit. The indoor unit is quiet in normal use; most noise comes from the outdoor unit. We place it away from bedrooms and neighbours and use anti-vibration mounts. The sound level of the proposed models is shown in the quote.
