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.
Can you work after trading hours?
Yes. Retail, restaurant and office work is routinely scheduled at night or early morning under a permit-to-work so trading is not interrupted.
There is water on the floor under my ice machine, can you find the leak?
We trace it wet rather than guessing: inlet valve weep, split distribution tube, blocked machine drain or a backed-up bin drain all present the same way. The water side is pressure-tested before we recommission.
How urgent is a slow harvest cycle?
Treat it as urgent. A stalling harvest leaves the plate frozen solid, output collapses and the compressor runs against high head pressure, which is how a cheap solenoid fault turns into a compressor replacement.
