Pipe length
Up to four metres is usually included. Every extra metre of copper costs material and labour, and beyond about 15 metres extra refrigerant is needed.

What moves the price up or down
Access
An outdoor unit on the third floor or a flat roof means scaffolding, a lift platform or a crane.
Routing method
Surface trunking is cheapest; chased-in pipework or shaft routing means more work and making good.
Electrics
A new protected circuit runs to €150–500 depending on the distance to the board.
Unit class
Between entry level and premium at the same capacity, expect €700–1,500 more – for a quieter, leaner, longer-lasting unit.
VAT
For work on an owner-occupied home, a reduced rate can be applied for in Luxembourg. We check the conditions with you before the order.
Ongoing costs
Example for a 2.5 kW unit in a bedroom over a typical Luxembourg summer.
| Item | Assumption | Cost per year |
|---|---|---|
| Electricity, cooling | 350 hours, 0.6 kW | €55–90 |
| Electricity, shoulder-season heating | 600 kWh heat, SCOP 4.5 | €30–45 |
| Maintenance | once a year | €140–180 |
| Filters and small parts | as needed | €0–40 |
Electricity prices move – redo the sum with your own tariff: kWh used multiplied by your price per kWh.
Is the more expensive unit worth it?
For summer cooling alone, a premium unit hardly pays for itself through electricity savings – the extra cost is justified by quietness, control quality and service life, not efficiency on its own.
As soon as you heat with it, the picture changes. A SCOP of 5.1 instead of 4.0 saves roughly 160 kilowatt-hours a year at a heat demand of 3,000 kWh, which adds up over fifteen years. If you plan to heat, do not save on the unit.
