Air conditioning system sizing

The right capacity depends on the room, not just its floor area

In cooling mode, an air conditioner extracts heat from the indoor air and releases it outside. It also removes some moisture while the compressor is running. In heating mode, the cycle reverses and the system operates as an air-to-air heat pump.

An undersized unit runs for long periods without reaching the setpoint. An oversized unit short-cycles, can create draughts and may dehumidify less consistently. We therefore calculate the requirement for each zone before selecting the units.

Direct answer: Ecoclima does not size air conditioning using an automatic W/m² ratio. We account for orientation, glazing, insulation, top-floor exposure, occupancy, appliances, the zones to be treated and the technical route.
Building envelope
Insulation, roof, glazing, solar shading and air leakage.
Heat gains
Orientation, sunlight, occupants, lighting, IT equipment and other appliances.
Zones
Rooms actually in use, doors, schedules and independent temperature settings.
Positioning
Indoor airflow, outdoor unit, line lengths, height differences and accessibility.
Acoustics
Sound power, sound pressure, vibration, reflective façades and neighbouring properties.

The Ecoclima air conditioning assessment

We validate the technical routes before selecting the equipment

The unit visible inside the room is only one part of the project. A reliable installation also depends on the outdoor location, line routing, condensate drainage, electrical work, noise and maintenance access.

What we examine on site

  • The rooms to be cooled or heated and their heat loads.
  • Indoor-unit positions that distribute air without disturbing occupants.
  • Outdoor locations compatible with access, noise constraints and maintenance.
  • The route for refrigerant pipes, cables and trunking.
  • Gravity condensate drainage or the need for an accessible pump.
  • The electrical panel, protection devices and any required procedures.

What our proposal contains

  • The configuration, selected capacities and exact equipment references.
  • Available seasonal performance, acoustic data and refrigerant.
  • The number of units, planned line lengths and condensate solution.
  • Included refrigerant, electrical and finishing work.
  • Clearly separated options, warranties and maintenance conditions.
  • The price, technical assumptions and installation process.

Single-split, multi-split, ducted or VRF

We select the configuration that genuinely suits the zones to be treated

The best system is not the one with the most units. It must provide the right control, integrate into the building and keep refrigerant and condensate routes manageable.

Single-split

One indoor unit connected to one outdoor unit. This solution is suitable when one room is the priority, such as a living room, an attic bedroom or an office.

  • Dedicated control for one zone.
  • Straightforward installation and maintenance.
  • One outdoor unit per system.

Multi-split

Several indoor units are connected to one outdoor unit. Each room keeps its own setpoint within the capacity and operating limits of the outdoor unit.

  • Two or more independently controlled zones.
  • Fewer visible outdoor units.
  • More detailed assessment of line lengths and simultaneous demand.

Ducted system or cassette

The indoor unit is integrated into a suspended ceiling or service void. Air is delivered through grilles or a cassette, with maintenance access planned from the design stage.

  • Discreet interior integration.
  • Airflow, acoustic and architectural assessment.
  • Suitable for planned renovations and new-build projects.

VRF / VRV

A variable refrigerant flow architecture serves numerous zones. It is designed for large homes, offices and commercial premises that require a centralised design.

  • Multiple units with zone-by-zone control.
  • Central monitoring options depending on the product range.
  • Dedicated sizing and commissioning.
Often overlooked: air conditioning does not renew indoor air. Depending on the equipment, it circulates, filters, cools or heats the room air, but suitable ventilation is still required to bring in fresh air.

Air conditioning in Luxembourg · 2026 information

For our 2026 projects, regulation forms part of the technical decision

We do not present a grant, VAT rate or refrigerant as an automatic sales argument. Our quotation distinguishes confirmed rules, checks specific to the building and decisions that remain with the authorities or co-ownership.

  • Refrigerants: R32 is not banned in 2026. EU rules nevertheless provide for a gradual transition towards lower-impact refrigerants.
  • New equipment: for air-to-air split systems up to 12 kW, placing new systems using fluorinated gas with a GWP of 150 or more on the market is prohibited from 1 January 2029, except where required to meet safety requirements.
  • Klimabonus 2026: standard reversible air-to-air conditioning is not included among the heat pumps eligible under Luxembourg’s national 2026 scheme.
  • VAT: the official “TVA Logement” scheme excludes air conditioning from the super-reduced 3% rate. Our 2026 ranges therefore use the normal 17% rate.

What the F-gas timetable actually means: it concerns placing new equipment on the market. It does not require an existing R32 system to be removed in 2029. In 2026, Ecoclima compares refrigerant, efficiency, acoustics, parts availability and long-term serviceability before proposing a product.

Our technical checks

  • Refrigerant compatibility and the manufacturer’s installation conditions.
  • Access to the refrigerant circuit restricted to qualified personnel.
  • Acoustic positioning and vibration control.
  • Comparison of outdoor sound power and indoor sound pressure.
  • Condensate drainage without nuisance discharge or standing water.

Building-related approvals

  • Municipal rules and any required permit where the façade or exterior is affected.
  • Approval from the co-ownership or building manager before work on common areas.
  • Additional constraints for a protected building or special area.
  • Any municipal grant checked before it is deducted from the budget.
  • Final decision by the competent authority on applicable procedures and benefits.

Information verified on 9 August 2026. Official sources: Regulation (EU) 2024/573, Annex IV, installations eligible for Klimabonus 2026, work excluded from the reduced housing VAT scheme and municipal building permits. The rules are checked again for every project.

Equipment and commissioning

We design the complete installation, not just the indoor unit

Comfort depends on the system as a whole: heat exchangers, compressor, fans, controls, lines, condensate drainage, electrical supply, positioning and settings. Our quotation identifies the proposed products and the work required for them to operate correctly.

We compare available capacity under the expected conditions, SEER and SCOP where applicable, modulation ranges, acoustics, filters, connectivity, refrigerant and access to after-sales support.

Indoor unit
Wall-mounted, floor console, cassette or ducted, with airflow suited to the room.
Outdoor unit
Capacity, modulation, refrigerant, acoustics, clearances and maintenance access.
Refrigerant circuit
Insulated pipes, connections, tightness checks, evacuation and commissioning.
Condensate
Gravity drainage wherever possible, or an accessible pump where required.
Electrical supply and controls
Protection devices, wiring, remote control, scheduling and available connected functions.
We do not choose a brand before understanding the project. Strong technical specifications cannot compensate for poor positioning, short cycling, uncomfortable airflow or unreliable condensate drainage.

Frequently asked questions

Ecoclima answers your questions about air conditioning in Luxembourg

How does reversible air conditioning work?

In cooling mode, it extracts heat from the indoor air and releases it outside through a refrigerant circuit. In heating mode, the cycle reverses and the system operates as an air-to-air heat pump. It treats the room air but does not bring in fresh air.

What is the difference between single-split, multi-split, ducted and VRF?

A single-split serves one zone with one indoor and one outdoor unit. A multi-split connects several indoor units to one outdoor unit. A ducted system distributes air through ducts from a concealed unit. VRF or VRV serves multiple zones in large residential or commercial projects.

How much does air conditioning cost in Luxembourg in 2026?

Ecoclima’s 2026 guide ranges are €2,500 to €4,200 for one room, €4,500 to €7,000 for two rooms and €6,800 to €12,000 for three to four rooms. They include quality equipment, a standard installation and normal VAT. The final price depends on line routes, condensate drainage, access and electrical work.

Does air conditioning use a lot of electricity?

Consumption depends on the heat load, setpoint, insulation, weather, operating hours and seasonal efficiency. Correct sizing, effective solar shading and a reasonable setpoint reduce consumption. Ecoclima does not provide universal euro estimates without usage data.

Can reversible air conditioning heat a property in winter?

Yes. It can efficiently heat one or more zones, particularly in milder weather. Before treating it as the main heating system, Ecoclima checks insulation, heat distribution between rooms, available capacity in cold weather and whether another system is required. It does not produce domestic hot water.

Does air conditioning renew indoor air?

Not in a conventional split installation. The indoor unit recirculates and treats air already present in the room. Depending on the model, filters may capture certain particles, but they do not replace airing or a ventilation system that supplies fresh air.

Does air conditioning dehumidify a room?

Yes. Water condenses on the heat exchanger when the system cools humid air, and it must be drained correctly. The effect depends on operation, sizing and indoor conditions; air conditioning is not always a substitute for a dedicated dehumidifier.

How can air conditioning noise be reduced?

Choosing the model is not enough. Ecoclima compares outdoor sound power and stated indoor sound pressure, then considers distance, reflective surfaces, vibration, the support, bedrooms and neighbouring properties. Night mode cannot correct poor positioning.

Do I need permission to install air conditioning in Luxembourg?

It depends on the municipality, building and location. An outdoor unit or visible wall penetration may affect the façade and be subject to municipal rules. In a co-owned building, approval may be required before altering a common area. Ecoclima identifies the issue during the assessment, but confirmation remains with the municipality, building manager or competent authority.

Is reversible air conditioning eligible for Klimabonus in 2026?

Standard reversible air-to-air conditioning is not included in the national list of heat pumps eligible for Klimabonus 2026. Any municipal grant must be checked separately. Ecoclima does not deduct a grant from the quotation until its applicability has been confirmed.

Does the 3% VAT rate apply to air conditioning in Luxembourg?

No, not under the “TVA Logement” tax scheme. The official Guichet.lu page explicitly lists air conditioning among work excluded from the super-reduced rate. Ecoclima’s 2026 estimates therefore use the normal 17% rate.

Is R32 refrigerant banned in 2026?

No. R32 is not banned in 2026. For air-to-air split systems up to 12 kW, EU rules prohibit placing new equipment using fluorinated gases with a GWP of 150 or more on the market from 1 January 2029, except where required to meet safety requirements. This timetable does not require an existing installation to be removed in 2029.

How often should air conditioning be serviced?

Filters should be checked and cleaned according to use and the manufacturer’s instructions. Professional maintenance frequency depends on the model, intensity of use, environment and refrigerant charge; there is no identical annual obligation for every small residential split. Ecoclima services and troubleshoots the systems it has installed.

How long does air conditioning installation take?

A straightforward single-split can generally be installed in one day, while a multi-split, ducted system or commercial project takes longer. The schedule depends on line lengths, wall penetrations, electrical work, condensate drainage, finishes, access and approvals.

Can air conditioning be powered by solar panels?

Yes. Cooling demand often partly coincides with daytime solar generation. This does not make air conditioning free: weather, setpoint, shading, occupancy and photovoltaic capacity remain decisive. Ecoclima can coordinate both systems without overstating self-consumption.

Does Ecoclima work throughout Luxembourg?

Yes. Ecoclima is based in Munsbach and operates throughout the Grand Duchy, including Luxembourg City, Esch-sur-Alzette, Differdange, Dudelange and all other municipalities. The site visit confirms access, unit positions, service routes and any address-specific procedures.
