Is VRF worth it for a small building?

Usually not. Below roughly six to eight zones, multi-split or separate splits are normally the better value.

Can you maintain an existing VRF system?

Yes, including planned maintenance, controller faults and leak investigation on installed systems.

VRF & VRV Air Conditioning in Melrose

What vrf & vrv air conditioning actually involves

VRF systems vary compressor output and refrigerant flow to match actual demand, so a building running at 30% occupancy does not pay for 100% cooling. They also allow many indoor unit types on one outdoor bank. The trade-off is that commissioning, pipe sizing and leak detection must be done to specification — these are not systems to improvise on.

Because Melrose sits within our core Johannesburg footprint, routine visits here do not carry long-distance travel charges. We confirm parking, access control and after-hours arrangements before attending.
