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 Dainfern this is luxury gated estates 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 Dainfern are condenser fouling behind grille and evaporator fan failure in freezer section.Every visit starts with a full diagnostic and a written quote before any part is fitted.Estate access requires resident pre-authorisation and vehicle inspection. Ice Machine Repairs bookings in Dainfern are logged against Block 13 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 Dainfern?
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.
