Servicing, maintenance and repair of air-to-water and air-to-air heat pumps in Liège (4000) and across the whole Meuse conurbation, from Outremeuse to the slopes of Cointe. Recommended annual visit, refrigerant circuit leak check, performance verification (COP) and all-brand after-sales support — a Liège-based team that keeps your manufacturer warranty intact.
We service heat pumps in Liège with a team of technicians who know the Meuse-valley building stock — from the townhouses of Outremeuse and Le Laveu to the villas on the slopes of Cointe and Sainte-Walburge. A well-maintained heat pump keeps its efficiency, uses less energy and lasts longer : the annual visit is the best way to protect both your investment and your bill.
The visit is scheduled at your home, with no hidden call-out fees ; the same team handles the maintenance visit, the refrigerant circuit leak check and the repair if a fault occurs, on every brand — whether or not we installed the unit.
What a maintenance visit checksBeyond the centre, we also service heat pumps in Outremeuse, Cointe, Sainte-Walburge and Le Laveu, as well as towards Seraing, Herstal and Visé. Need a new installation rather than maintenance ? See our heat pump in Liège page.
Servicing a heat pump does not qualify for a grant, unlike installation (Walloon Habitation grant, reduced VAT). But a serviced heat pump costs less to run and stays under warranty : here is what our follow-up covers.
One visit a year keeps efficiency up, spots wear before it becomes a breakdown and is part of the good practice recommended by manufacturers. Full check, cleaning and adjustments included.
Most manufacturers make their warranty conditional on regular servicing by a professional. We carry out compliant, documented maintenance so your warranty stays valid.
Our maintenance contract schedules the annual visit, covers the leak check and gives you priority access to repairs — all brands, whether we installed the unit or not.
Considering a new installation instead ? The full breakdown of amounts, grants and conditions is on our heat pump pricing & grants page. For maintenance, we draw up a clear quote based on the type and brand of your unit.

Yes, for installations whose refrigerant charge exceeds certain thresholds, a periodic leak check of the refrigerant circuit is a legal requirement, to be carried out by a qualified technician. We check your Liège heat pump’s charge, perform the required test and record it in the job report.
The price depends on the type of heat pump (air-to-water or air-to-air), the number of units and whether a leak check is required. We provide a clear quote with no surprises before any work. Note: maintenance is not subsidised, unlike installing a heat pump, which qualifies for the Walloon Habitation grant and 6% VAT.
The maintenance contract automatically schedules your annual visit, covers the refrigerant circuit leak check and gives you priority access to repairs. It also secures your manufacturer warranty, which is often conditional on regular servicing by a professional.
