Air conditioning & air-to-air heat pump simulator for Luxembourg: power, price and running cost

The Renov.lu air-conditioning simulator estimates the cooling capacity needed (kW), the installation budget (install included), the energy cost and the feasibility of your air conditioning or air-to-air heat pump project in Luxembourg. Note: air conditioning (air-to-air heat pump) is not eligible for the Klimabonus — but installation can qualify for the 3% housing VAT.

How much cooling power per m²?

Allow roughly 60 to 100 W of cooling per m² depending on insulation, exposure and ceiling height. Benchmarks for average insulation in Luxembourg:

Multisplit€4,300 – 12,0002 to 5 rooms — the most common
Ducted€11,000 – 28,000Whole house, discreet finish

Consumption and energy cost

Modern units have a SEER of 6 to 8: they deliver 6 to 8 kWh of cooling per kWh of electricity. With electricity at ~€0.26/kWh (Luxembourg 2026) and mild summers, expect typically €20 to €40/month in summer for a well-sized home.

Grants: air conditioning / an air-to-air heat pump is not eligible for the Klimabonus (reserved for air-to-water and geothermal heat pumps on a central heating circuit). The only benefit is the 3% housing VAT on installation when renovating a home older than 2 years.

Permits and obligations

The installation must be carried out by an F-Gas certified engineer and inspected by the Chamber of Trades (Grand-Ducal regulation of 13/08/2025, request within one month of commissioning). In co-ownership, the façade outdoor unit needs the building manager's approval. Boundary noise: ≤ 55 dB by day / 45 dB at night.

How to use the simulator

  1. Describe the home: area to cool, insulation, exposure, ceiling height.
  2. Specify the project: cooling only or + backup heating, number of rooms, unit type.
  3. Get your estimate: cooling capacity, budget (install included), energy cost, feasibility and a free PDF report.

How much does air conditioning cost in Luxembourg in 2026?

€2,300 to €4,000 for a monosplit (1 room), €4,300 to €12,000 for a multisplit (2-5 rooms) and €11,000 to €28,000 for a whole-house ducted system — installation included. On average, budget €2,300 to €2,600 per split.

What air-conditioning power should I choose?

About 60 to 100 W of cooling per m² depending on insulation and exposure. The simulator computes the peak capacity in kW from your home.

Does air conditioning consume a lot of electricity?

No: with a SEER of 6 to 8 and short Luxembourg summers, the energy cost is moderate, around €20 to €40/month in summer.

Is air conditioning eligible for the Klimabonus?

No. The Klimabonus is reserved for air-to-water and geothermal heat pumps. Air conditioning (air-to-air) only qualifies for the 3% housing VAT.

Do I need a permit to install air conditioning?

Yes: an F-Gas certified installer is mandatory, the system must be inspected by the Chamber of Trades, co-ownership requires the building manager's approval, and noise limits apply (55 dB day / 45 dB night).

Air conditioning (air-to-air) or an air-to-water heat pump?

Air-to-air cools (and heats as a backup) with no State grant. To heat the whole home and replace a boiler, choose an air-to-water heat pump, eligible for the Klimabonus (€6,000 to €12,000).
