How many indoor units?
VRV Aircon Systems South Africa run many indoor units from one outdoor plant, varying refrigerant flow to each so every zone gets what it needs and no more. They are what larger offices and multi-tenant buildings use once individual splits stop making sense.

Get the Best QuoteHow VRV and VRF Work
- One outdoor plant. A modular condenser, often on the roof.
- Many indoor units. Cassettes, ducted units and wall units on one system.
- Variable flow. Refrigerant sent to each zone in proportion to demand.
- Heat recovery. Some systems move heat from a cooling zone to a heating one.
- Zoning by default. Every indoor unit is its own zone, controlled separately.
- The name. VRV is one manufacturer's term for what others call VRF.
When It Is the Right Answer
- Many separate spaces. Roughly eight or more indoor units.
- Limited outdoor space. One plant area instead of a wall of condensers.
- Multi-tenant buildings. Consumption can be metered and billed per tenant.
- Mixed loads. A sunny side cooling while a shaded side heats.
- Long building life. The capital cost is recovered over years, not seasons.
- Not a house. For most homes a multi-split is the right scale.
What to Settle Before Committing
- Design responsibility. Who sizes it, and who carries it if it is wrong.
- Controls. Central control, per-zone control, or a building management link.
- Metering. Essential if tenants pay for their own consumption.
- Maintenance. Specialist, and priced accordingly; get it quoted up front.
- Commissioning. A long process on a large system and worth watching.
- Refrigerant volume. Large charges bring their own safety requirements.

Get the Best QuoteWhat Affects the Price
- Number of indoor units. The main driver of both plant and pipework.
- Total capacity. From the load calculation, zone by zone.
- Heat recovery or heat pump. Recovery costs more and saves more in mixed buildings.
- Pipe routes. Riser availability and run lengths in an existing building.
- Controls and metering. A substantial line in a multi-tenant building.
- Crane and access. Plant on a roof has to get there.
What to Include in Your Request
- The building. Floors, floor area and how it is divided.
- Number of spaces. And which need independent control.
- Occupancy and hours. Per floor or per tenant if they differ.
- Existing plant. What is there now and whether it is being replaced.
- Riser and roof access. Whether there are routes for pipework and plant.
- Metering needs. Whether tenants are billed separately.
Before the HVAC Company Quotes
- Get the load calculation. On a system this size it is not optional.
- Ask who carries the design. Supplier, contractor or a consulting engineer.
- Price the maintenance first. It runs for the life of the system.
- Ask about spares and support. Local stock and factory backing for that brand.
- Ask about commissioning. Who signs it off, and against what.
- Compare against alternatives. Ducted or multiple splits, priced the same way.
VRV Aircon Systems FAQs
What is the difference between VRV and VRF?
Nothing technical. VRV is Daikin's trademark for the technology and VRF is the generic term everyone else uses, so a VRV system and a VRF system are the same kind of thing: one outdoor plant varying refrigerant flow to many indoor units. Quotes will use either word and sometimes both.
Is VRF worth it for a small office?
Usually not below about eight indoor units. Below that the capital cost is hard to justify against individual splits or a ducted system, and the maintenance is more specialised. Above it, the savings in outdoor space, the zoning, the metering and the running efficiency start to make the case on their own.
Can VRF heat and cool at the same time?
A heat recovery system can, which is the main reason to choose one over a straightforward heat pump VRF. In a building where one side is in sun while the other is in shade, it moves heat from the zones that want rid of it to the zones that want it, and that is where the efficiency gains come from.
How is a VRF system maintained?
On a planned contract, by a company accredited for that brand. The indoor units need routine filter and coil work like any other, and the outdoor plant and controls need specialist attention. Get maintenance quoted before you commit to the system, because it is a long-term cost and it varies a great deal between providers.
Can tenants be billed for what they use?
Yes, with a metering system that apportions consumption per indoor unit or per tenant area. It is a standard requirement in multi-tenant buildings and it is far cheaper to install with the system than to add afterwards, so it belongs in the brief from the start.
VRV and VRF systems are among the types providers listed on Aircon Hub quote for, alongside ducted, cassette and rooftop plant.
