Common questions
How quickly can a coldroom be back at temperature?
Once the fault is cleared, a well-insulated coldroom pulls back down within two to four hours. We advise on stock protection during that window.
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.
My ice machine runs but makes no ice, is it worth repairing?
Usually yes. The four common causes (water inlet valve, water pump, scaled evaporator and a stalled harvest cycle) are all repairable at a fraction of replacement cost. We quote in writing after the diagnostic and tell you honestly when a machine is past economic repair.
Why is my ice cloudy or melting too fast?
Cloudy, soft ice means the freeze cycle is being cut short or the water is carrying too many dissolved solids. We test hardness and TDS on site, fit the right filtration, descale the plate and re-time the cycle so cubes freeze clear and hard.
