Common questions
Is an LG linear compressor worth repairing in Wierda Valley?
On refrigerators still within their ten-year sealed system warranty, yes. Outside it, we quote the compressor and drier replacement against the value of the unit so you can decide on the numbers rather than a guess.
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.
