For a smaller residence ranging from 10-25 m2, such as a studio apartment with just one room, a Single-Zone system is sufficient.
We always recommend investing in a quality machine from a premium brand, preferably a model with a slightly higher output than strictly necessary. This ensures that, when properly maintained, you have a system that will last for many years to come. You also get a unit that can effortlessly provide a comfortable indoor climate regardless of the season or extreme temperature changes.
