VRF installation and fresh-air ventilation for a 120-room hotel.
Multi-zone air conditioning
VRF / VRV air conditioning
A VRF system gives dozens of rooms individually controlled temperatures from one outdoor unit. Its complex refrigerant piping needs correct installation and professional diagnostics.
About the service
VRF systems are an energy-efficient and flexible choice for offices, hotels and residential buildings. But their reliability depends directly on the cleanliness, tightness and correct charge of the refrigerant piping.
During installation we pressure-test the piping with nitrogen, evacuate it and charge it with the calculated amount of refrigerant. In operation we read error codes to pinpoint faults.
What we check during service
- Outdoor unit compressors and fans
- Pressure and leak search on refrigerant lines
- Indoor unit filters and drainage
- Cleaning cassette and ducted units
- Central controller check
- Reading and analysing error codes
- Electronic expansion valves
- Condensate pump operation

Questions
Water is dripping from an indoor unit — why?
Most often a blocked drain line or a faulty condensate pump. It is usually fixed in one visit.
There's an error code on the display — what should I do?
Send us the code and the unit model. We can often give initial guidance by phone and send a technician the same day if needed.
Can a new indoor unit be added to an existing VRF system?
Yes, if the outdoor unit capacity and pipe length allow. We run the calculation first.
