VRV and VRF systems cool many rooms from one set of outdoor units, with each zone controlled separately. Winsteam designs, installs and replaces VRV / VRF systems for offices, shops, clinics, homes and hotel back-of-house areas across Singapore — from sizing the system to commissioning it.
New systems and replacements, designed around how the building is actually used.
Cooling load for each zone, outdoor unit capacity, indoor unit selection and refrigerant pipe layout, sized for how the space is actually used rather than a rule of thumb.
Supply and installation of outdoor units, indoor units (cassette, ducted, wall-mounted), refrigerant piping, condensate drainage, power and controls.
Replacing VRV / VRF systems that are past their service life, unreliable or running on phased-out R22 refrigerant, with current high-efficiency systems.
Replacing outdoor condensing units, with a check on whether existing indoor units and piping can remain.
Pressure testing and assessment of existing refrigerant pipes to decide whether they can be reused, saving ceiling works, or must be renewed.
Individual and central controllers, scheduling, vacuum and pressure testing, refrigerant charging, and commissioning of every indoor unit before handover.
Floors with many rooms and varied hours.
Shops and outlets needing zone control.
Consultation rooms with separate comfort needs.
Multiple bedrooms on one system.
Offices, staff areas and support rooms.
Classrooms and admin blocks.
| VRV / VRF | Chilled Water | Split Units | |
|---|---|---|---|
| Best for | Many zones, small to mid-size buildings | Large buildings, high continuous loads | A few independent rooms |
| Zone control | Individual per room | Per AHU / FCU zone | Per unit |
| Plant space | Compact outdoor units | Chiller plant, pumps, cooling towers | One outdoor unit per system |
| Part-load efficiency | High — inverter matches demand | High at large scale with good controls | Good for inverter models |
| Upfront cost | Moderate | Highest | Lowest |
Not sure which suits your building? Winsteam also designs and installs chilled water ACMV systems — we recommend what fits, not what is easiest to sell.
We inspect the existing units, piping routes, power supply and outdoor unit location, and note how each area is used and when.
Cooling loads, system capacity, indoor unit types and pipe layout, with a clear scope and whether existing piping can be reused.
Outdoor and indoor units, piping, drainage and controls installed in phases where the premises stays occupied, with works planned around your operating hours.
Pressure and vacuum tests, refrigerant charging, system start-up and testing of every zone, then handover with as-built drawings and warranty documents.
VRV / VRF systems are quoted from the site, not a catalogue. Sending these with your enquiry lets us come to the survey prepared — and quote faster.
Whether this is a new installation or a replacement, which areas need cooling, and what triggered the enquiry — breakdowns, high power bills, renovation, R22 phase-out.
Type of premises, the rooms or zones to be cooled, approximate floor area, and where the outdoor units are or can go.
For replacements: the nameplate of the outdoor units (model and HP), the number and type of indoor units, and roughly how old the system is.
Phone photos of the outdoor units, their nameplates, the indoor units and the space they serve.
Operating hours, whether areas must stay in use during works, and whether the premises is owned or leased (landlord or MCST approval may be needed).
When you need it working — and whether there is an inspection, audit or complaint driving the date.
Tell us the problem and send a few photos. We’ll arrange a site survey at no obligation and tell you plainly what will work.
