Real Project: Office AC in Kirchberg
Commercial Installation
Kirchberg Business District
A law firm in Kirchberg needed climate control for 6 offices and a conference room. We designed a multi-split system where each room has its own temperature control — so everyone's comfortable. We scheduled the install over a weekend so it didn't disrupt their work.
The system uses energy-efficient inverter units with WiFi control. Compared to their old portable units, energy costs dropped by an estimated 30%. We also set them up with an annual maintenance plan to keep everything running smoothly.

Air conditioning in Luxembourg — emergency repair and planned installation
AC & heat-pump emergencies
- AC stopped during a heatwave — office, server room or shop overheating
- Heat pump no longer heating in winter, house dropping below 15 °C
- Water leaking from the indoor unit onto the floor or ceiling
- AC making loud noise, ice forming on the outdoor unit
- Strong refrigerant smell or repeated tripping of the AC breaker
Planned AC & heat-pump work
- New split, multi-split or ducted installation (Daikin, Mitsubishi, LG, Toshiba)
- Air-air heat pump for an apartment or single-family house
- Annual maintenance and mandatory leak check for R32 systems
- Replacing an old R22/R410A system with a modern R32 unit
- Commercial HVAC for restaurants, server rooms, retail and offices
Diagnosis from the first call
What's the brand? Indoor unit dripping or outdoor unit silent? Error code on the remote? Three questions tell us if it's a clogged condensate line, a low gas charge or a faulty inverter board. The technician arrives with the right gauges, the right R32 cylinder and — when possible — the right spare board.
Fully-equipped HVAC van
On board: R32 cylinders, manifold gauge set, vacuum pump, electronic leak detector, nitrogen for pressure testing, brazing kit, common spare boards for Daikin / Mitsubishi / LG, condensate pumps and a full set of insulation and copper line-sets. Certified handling of refrigerants according to EU F-Gas regulation.
Why Luxembourg chooses us for AC and heat pumps
Six guarantees behind every installation, maintenance visit or emergency AC call.
Quote agreed before the gauges go on
Installation price, repair price, maintenance price — confirmed in writing before any work begins. No "refrigerant top-up" mystery line on the final invoice.
F-Gas certificate & paperwork for insurance
Every R32 intervention is logged. You receive the F-Gas leak-check certificate required by EU law and accepted by your insurer in case of water damage from the AC.
Luxembourg-registered HVAC company
Registered at the Chambre des Métiers, Luxembourg VAT, F-Gas certified technicians. Eligible installations can also help you with Klimabonus paperwork.
Installation & repair guarantee
Manufacturer warranty on the equipment plus our own workmanship guarantee on the brazing, vacuum and electrical wiring. Both written on the invoice.
WhatsApp a photo or error code
Send the model sticker, the error code on the remote or a photo of the dripping unit. We often identify the part before the van leaves the depot.
A real HVAC technician on the line
When you call, you speak to someone who installs and repairs AC every day — not a generalist guessing what "E5" might mean on your Daikin remote.
