Fault diagnosis
Common MDV aircon faults we investigate

- Outdoor fan or compressor trip
- Refrigerant shortage caused by a leak
- VRF address or communication faults
How diagnosis is handled
MDV systems are checked in a logical sequence: power supply, controls, sensors, motors, airflow and refrigeration performance. This approach separates an equipment fault from an installation or maintenance problem.
For modular MDV systems, each connected outdoor module and indoor group must be assessed. We inspect communication, oil return conditions, refrigerant balance and the status of common control components.

Customer questions
Frequently asked questions
Do you repair MDV air conditioners?
Yes. Topworks provides inspection, fault finding, servicing and repair support for MDV split, commercial and VRF systems. Parts availability and repair viability are confirmed using the model and serial information.
How much does a MDV aircon service cost?
A standard wall-split major service is normally estimated at R750–R1,200. Cassette, ducted, VRF and chiller systems cost more because access, size and testing requirements differ.
Can you repair a MDV aircon that is not cooling?
Yes. The technician checks airflow, coils, fan operation, sensors, electrical controls, refrigerant pressure and signs of leakage before recommending gas or replacement parts.
Do you install new MDV systems?
Installation can be quoted after confirming capacity, pipe route, drainage, electrical supply, outdoor-unit position and equipment availability.
Do you offer commercial maintenance for MDV?
Yes. Planned maintenance can be arranged for offices, retail, hospitality, healthcare, industrial and multi-unit sites after an equipment survey.
