Pressure testing, leak detection, vacuum and accurate weighed re-gas of R410a, R32 and legacy R22 systems. In Kyalami this is corporate & commercial work on all split types systems, attended within about 80 minutes of dispatch.On Midea equipment specifically — value inverter splits, cassettes and hot water heat pumps — the faults we see most in Kyalami are four-way valve sticking in heating mode and outdoor fan capacitor failure.Every visit starts with a full diagnostic and a written quote before any part is fitted.Smallholdings and estates; borehole water common. Aircon Repairs & Servicing bookings in Kyalami are logged against Block 16 so we can allow for power availability on site.

Refrigerant data
| Gas | Classification | Suction pressure | Discharge pressure | Typical use |
|---|---|---|---|---|
| R410a | HFC blend (A1) | 280-320 kPa at 7 degrees C evaporating | 2 600-3 000 kPa at 45 degrees C ambient | Most inverter splits, ducted systems, VRV/VRF and heat pumps installed since 2005. |
| R32 | HFC (A2L, mildly flammable) | 300-340 kPa at 7 degrees C evaporating | 2 700-3 100 kPa at 45 degrees C ambient | Current-generation inverter splits and heat pumps. |
| R22 | HCFC (phased out) | 480-520 kPa at 7 degrees C evaporating | 1 700-2 000 kPa at 45 degrees C ambient | Legacy splits and ducted plant installed before the phase-out. |
Common questions
My Midea unit heats but will not cool. What is wrong in Kyalami?
That points to the four-way reversing valve sticking or its solenoid coil failing. It can often be freed and the coil replaced without opening the sealed system.
How often should an aircon need re-gassing?
A correctly installed system should never need gas. If it does, there is a leak, so we pressure test and repair the leak before charging rather than topping up annually.
Do you charge a callout fee?
A standard callout and diagnostic fee applies and is quoted upfront. It is credited against the repair when you accept the quote.
