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 often should an aircon need re-gassing?
A correctly installed system should never need gas. If it does, there is a leak, so we pressure test and repair the leak before charging rather than topping up annually.
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.
