Pressure testing, leak detection, vacuum and accurate weighed re-gas of R410a, R32 and legacy R22 systems. In Strathavon this is sandton prime work on all split types systems, attended within about 45 minutes of dispatch.On Dunham-Bush equipment specifically — industrial chillers, fan coils and commercial hvac plant — the faults we see most in Strathavon are oil return problems on long pipe runs and compressor contactor failure.Every visit starts with a full diagnostic and a written quote before any part is fitted.Mixed sectional title; body corporate approval for plant changes. Aircon Repairs & Servicing bookings in Strathavon are logged against Block 4 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
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.
How fast can you get to me?
Emergency callouts are dispatched to the next available technician, with the arrival window confirmed by SMS when the vehicle leaves.
Do you top up gas without finding the leak?
No. A weighed charge into a leaking system is money out the window, so the leak is found and repaired first, then the system is evacuated and charged to the plated weight.
