Common questions
My Midea unit heats but will not cool. What is wrong in Kyalami Business Park?
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.
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.
What does an annual service contract include?
Scheduled visits, priority response between visits, a written condition report per unit and fixed labour rates for the contract year.
Is a compressor replacement guaranteed?
Yes. Replacements are done with a system flush and new drier, and both part and workmanship are warranted, provided the original cause of failure is corrected.
