What does air conditioning installation cost in Belgium in 2026?
Last updated: April 2026
Air conditioning has become an indispensable appliance in Belgian homes. With more than 300,000 new installations in 2025 — an absolute record — demand for air conditioners is greater than ever. Modern split-unit air conditioners are not only suitable for cooling in summer, but are increasingly used as efficient heating in spring and autumn. This cost guide provides a clear overview of typical 2026 prices, the main cost components, and the choices that make the biggest difference.
Price indications range between €1,500 and €4,500 per installation, based on current 2026 market data. The price depends on the type of system (single-split or multi-split), the power in kW, the chosen brand, and the complexity of the installation. A certified refrigeration installer is legally required for working with refrigerants. Brands such as Daikin, Mitsubishi Electric, and Fujitsu are known for reliability and high COP values.

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.
