This is an estimate based on average 2026 prices. Actual costs may vary. Always request multiple quotes for an exact price.
Cost factors
The total cost usually consists of:
- Indoor and outdoor unit: 45-60% of the total
- Installation and refrigerant piping: 25-35% of the total
- Electrical connection and wiring: 10-15% of the total
- Wall penetrations, brackets, and finishing: 5-10% of the total
These percentages can vary depending on the chosen system, power, and length of the piping.
Why do prices vary?
- Single-split vs. multi-split: A single-split cools or heats one room and is cheaper. A multi-split with multiple indoor units on one outdoor unit is more expensive but more efficient for multiple rooms.
- Capacity and room size: The required power (expressed in kW or BTU) depends on the size and insulation of the room. An incorrectly sized system is inefficient.
- Brand and EPC rating: Brands like Daikin and Mitsubishi Electric are more expensive to purchase but have higher COP values and last longer than cheaper alternatives.
- Pipe length and wall penetrations: The more meters of piping to be laid and the more walls to be drilled through, the higher the installation costs.
Subsidies & incentives
In Belgium, a standard cooling-only air conditioning system usually does not qualify for a fixed grant. Only systems that also count as an air-to-air heat pump under regional rules may be eligible.
Flanders
- Check whether your system qualifies under Mijn VerbouwPremie as an air-to-air heat pump. A regular cooling installation without the required specifications does not receive automatic support.
- The installation must be carried out by a certified refrigeration or HVAC installer.
Wallonia and Brussels
- Here too, eligibility mainly depends on whether the system is recognised as a heating solution rather than cooling only.
- In Brussels, check current support via Homegrade or the RENOLUTION portal, because scheme details can change.
What usually matters more
- For homes older than 10 years, installation by a contractor can often qualify for 6% VAT.
- Electrical upgrades, condensate drainage, and pipe length often affect the total price more than any grant.
Local considerations in Luik
Above average (+8%)Wide price spread due to older housing stock, elevation differences, and varying accessibility by neighborhood.
Housing characteristics in Luik
Liege combines dense urban heritage with hillside districts and a large share of older housing. That leads to many projects around energy upgrades, roof work, and replacement of technical systems, often with extra attention to accessibility and transport.
- many older masonry townhouses and apartment buildings
- slopes and stepped streets make logistics harder
- renovations often focus on roofs, windows, and heating
- mix of older housing and upgraded neighborhoods
- good accessibility but clear urban pressure
- steady demand for energy and renovation work
- a certified refrigeration or HVAC installer is legally required for refrigerant work
- pipe length and number of wall penetrations also determine the installation price
