Cooling in summer 2026
Buy and install air conditioning — or plan it with your prefabricated house
Split, multi-split or portable air conditioner? We explain which system suits your home, what purchase and installation cost, and arrange free quotes.
Air conditioners compared: split, multi-split, portable & hose-free
From portable hose units to whole-house multi-split systems, your choice determines cooling capacity, noise and electricity costs.
Split air conditioner
A quiet indoor wall unit and an outdoor unit provide efficient, reliable permanent cooling. Installation requires a certified refrigeration contractor.
Multi-split air conditioner
One outdoor unit connects to two or more indoor units — ideal for cooling several rooms or a larger home.
Portable air conditioner
Portable monoblock units work without installation and vent through a window hose. They are practical for rented homes, but louder and less efficient than split units.
Air conditioner without an exhaust hose
These are usually water-based evaporative coolers that barely lower room temperature. Genuine cooling requires a split unit or a heat pump with cooling.
Air conditioning for apartments, houses, lofts & bedrooms
Air conditioning for an apartment
A fixed split unit in a rented apartment requires the landlord’s consent. Without it, a portable unit with a window seal is the practical solution.
Air conditioning in a house & loft
Lofts and south-facing rooms heat up most. Multi-split systems or individual units cool them selectively; a contractor plans pipes, drainage and the outdoor-unit location.
Air conditioning in the bedroom
Quiet operation, draught-free airflow, a timer or night mode and correctly sized capacity are crucial for restful sleep.
New build & prefabricated house
Cooling is cheapest when planned from the outset: a heat pump with active or passive cooling, optionally supplemented by a split unit. Pipes and openings can be prepared at the factory.
Air conditioning: installation costs at a glance
These are typical market guide prices as of 2026. The actual price depends on capacity, brand, pipe routes and region; the contractor’s quote is binding.
| Solution | Guide price incl. installation | Note |
|---|---|---|
| Portable air conditioner (monoblock) | approx. €200–800 | No installation, but higher electricity use and noise. |
| Split air conditioner, 1 room | approx. €1,500–3,500 | Unit and professional installation, depending on capacity, brand and pipe route. |
| Multi-split (2–4 rooms) | approx. €3,500–9,000 | One outdoor unit and several indoor units; effort varies by property. |
| Heat-pump cooling in a new build | often a small surcharge | An option from many prefabricated-house providers. |
Non-binding guide values; regional prices and installation effort can vary. Running electricity costs depend on use and efficiency.

Which air-conditioning system interests you?
Heat pump or air conditioning? Heating & cooling in one system
A split air conditioner is technically an air-to-air heat pump and can also heat. Many modern heat pumps cool through underfloor heating. Comparing both options is particularly worthwhile in a new build.
Air conditioning as heating
Split units heat efficiently in transitional seasons and provide flexible room-by-room support in well-insulated houses.
Heat pump with cooling
Gentle surface cooling without draughts or extra indoor units, often available as an option for the heat pump already installed in a new prefabricated house.
Combination in a new build
Many families combine a whole-house heat pump with a split unit in the loft. Factory planning avoids expensive retrofitting.

Planning a new build? Include cooling from the outset
Factory-planned cooling is cheapest: a heat pump with cooling, prepared pipes or a planned split system. We connect you with suitable providers free of charge.

- Compare providers for heat-pump cooling or split systems
- More than 35 prefabricated-house providers compared
- 100% free & no obligation
Note: no provider includes split air conditioning universally as standard. Heat pumps are standard and cooling is offered individually, which is why comparison pays.

Daikin, Mitsubishi, Panasonic & others: what matters in a brand
Established manufacturers such as Daikin, Mitsubishi Electric, Panasonic, LG, Samsung, Bosch and Midea offer efficient, quiet split units with good parts availability. Correct sizing, efficiency, indoor-unit noise and professional installation matter more than the brand name; compare several quotes.
