Heat pump servicing and maintenance for commercial buildings
Heat pump servicing in a commercial building covers regular inspections, checks of operation and operating parameters, the changeover between heating and cooling, leak checks of the refrigerant circuit, and fault diagnostics and repairs. It is intended for companies, building owners and facility managers with large heat pumps. We work across Slovenia.

The heat pump in both modes
In a commercial building, a heat pump often provides both heating and cooling. During an inspection we check operation in both modes, the operating parameters, the control settings and the condition of the finned air coil.

Refrigerant circuit
Leak check, refrigerant charge check and four-way valve operation.
Controls
Reviewing settings, alarms and the changeover between heating and cooling.
We recommend two inspections a year
Before the heating season
Changeover to heating, checks of operation and operating parameters, a leak check of the refrigerant circuit and a review of the controls.
Before the cooling season
Changeover to cooling, cleaning of the finned air coil and checks of operation in cooling mode.
Frequently asked questions
How often does a heat pump need servicing?
For heat pumps in commercial buildings we recommend two inspections a year, at the changeover to heating and at the changeover to cooling. We also follow the manufacturer’s instructions.
Do you also handle the changeover between heating and cooling?
Yes. The changeover between modes is part of our service, and we check that the unit works correctly in the new mode.
Does a heat pump need a refrigerant leak check?
For equipment where F-gas legislation requires it, we carry out the periodic refrigerant leak check and issue a certificate. Leak checks are mandatory for equipment containing 5 tonnes of CO₂ equivalent or more of F-gases (Regulation (EU) 2024/573).
Do you service Clivet and Daikin heat pumps?
Yes. We are an authorised service partner for Clivet and Daikin. We also service equipment from other manufacturers.
Do you also work outside Ljubljana?
Yes, we provide servicing and maintenance across the whole of Slovenia.
