Ice machine re-gassing with proper leak detection first: we find and fix the leak, then weigh in a fresh charge rather than topping up. In Midrand this is corporate & commercial work on sealed refrigeration system systems, attended within about 70 minutes of dispatch.On Sub-Zero equipment specifically — built-in refrigeration columns, wine storage and integrated units — the faults we see most in Midrand are control board and sensor faults and condenser fouling behind grille.Every visit starts with a full diagnostic and a written quote before any part is fitted.Mixed residential and industrial access. Ice Machine Repairs bookings in Midrand are logged against Block 15 so we can allow for power availability on site.

Refrigerant data
| Gas | Classification | Suction pressure | Discharge pressure | Typical use |
|---|---|---|---|---|
| R134a | HFC (A1) | 80-140 kPa at -5 degrees C evaporating | 900-1 200 kPa at 45 degrees C ambient | Wine cellars, display cabinets, medium-temperature commercial refrigeration and some heat pumps. |
| R404A | HFC blend (near-azeotropic) | 40-60 kPa (approx. 2-4 bar) | 1500-1900 kPa | Older commercial ice machines, cube makers, ice bins and blast chillers |
| R448A | HFO/HFC blend (low GWP) | 50-75 kPa | 1600-2000 kPa | Modern commercial ice machines, cube and flake units, coldroom retrofits |
| R290 (propane) | Natural hydrocarbon (A3 flammable) | 30-50 kPa | 1000-1400 kPa | Undercounter and self-contained ice makers, nugget machines, back-bar units |
Common questions
Can a built-in Sub-Zero be repaired without removing the joinery in Midrand?
In most cases yes. The units are designed to be serviced from the front through the grille and toe panel; full de-racking is only needed for sealed system work.
Can you just top up the gas in my ice machine?
No: a machine low on refrigerant has a leak, and topping up hides it. We leak-trace electronically and under nitrogen, repair the joint, fit a new drier, pull a deep vacuum and weigh in the exact plated charge.
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.
