Heat pump servicing

No legal inspection as for a boiler, but the manufacturer's warranty almost always asks for it. Refrigerant circuit, outdoor unit, filters, pressures and settings checked every year.

What the law says

The warranty

Most manufacturers require proven servicing to extend the warranty beyond the 2 legal years; Atlantic asks for a service at least every 2 years.

The refrigerant

The legal leak check only covers large charges (from 7.4 kg of R32). We check the circuit's tightness at every service and keep the logbook.

The efficiency

A neglected heat pump can use up to a quarter more: clogged filters, blocked outdoor unit, drifted settings.

2 years

of legal warranty, without proof of servicing

Without proof of servicing, the warranty often stops there. Vaillant grants its 3 extra years only to a serviced appliance, Viessmann asks for a maintenance contract.

The usual service life of a heat pump: servicing helps reach it.

Frequently asked questions

Both parts: the boiler at the legal pace of its fuel, the heat pump every year. One visit covers both.

Yes, between two services, if the manufacturer allows it. Checking the circuit, pressures and settings stays a technician's job.

Usually the occupant. In Brussels, the tenant arranges the inspection unless the lease names the owner or the property manager. In Flanders, the user is responsible and gives the owner a copy of the certificates.

That is no longer a service: see our page Urgent repair.
