Common questions
My Midea unit heats but will not cool. What is wrong in Mall of Africa Precinct?
That points to the four-way reversing valve sticking or its solenoid coil failing. It can often be freed and the coil replaced without opening the sealed system.
Is a heat pump geyser worth repairing or should I replace it?
If the tank and compressor are sound, repairs are far cheaper than replacement. Where the compressor has failed on a unit older than eight years, we quote both options side by side.
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.
