Heat pump and solar panel maintenance
Annual servicing and quick help with breakdowns, also for systems from another installer.

A well-maintained system uses less energy, lasts longer and breaks down less often. On top of that, many manufacturers require annual servicing to keep your warranty valid. We service heat pumps and solar systems in the Leuven region, even if you didn’t buy them from us.
Servicing your heat pump
During a service visit we check, among other things:
- how the controls work and are set, so the heat pump doesn’t use more energy than necessary;
- the outdoor unit: evaporator, fan and condensate drain;
- pressure and water quality in the system, filters and circulation pumps;
- the refrigerant circuit for leaks, where necessary or mandatory;
- the error log of the past year.
After the service you get a short report with any points of attention and tips to heat even more efficiently.
Checking your solar panels
Solar panels need little maintenance, but a periodic check is worthwhile. We inspect the inverter and cabling, compare the yield with the expected yield, and track down faulty panels or shading issues. Has your yield suddenly dropped? We’ll come and take a targeted look.
Breakdown?
Customers with a maintenance contract get priority for breakdowns. We’re usually on site the same or the next working day. Call us directly for an urgent breakdown; for a regular service visit you can use the form.

Frequently asked questions
How often should a heat pump be serviced?
We recommend annual servicing. Many manufacturers also require it as a warranty condition. For heat pumps with a larger refrigerant charge, a periodic leak check is also mandatory.
How much does a service visit cost?
A standard service of an air-to-water heat pump costs between 150 and 250 euros, depending on the type of unit. With a maintenance contract, we schedule it automatically every year.
Do you also service units bought elsewhere?
Yes, for most common brands of heat pumps and inverters. Mention the brand and model in your request and we'll confirm in advance whether we can help.
