Common questions
My Midea unit heats but will not cool. What is wrong in Sandton CBD?
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.
Why is my pool heat pump tripping on flow error?
Nine times out of ten it is a partially blocked filter, a closed valve or a failing flow switch. Water flow through the exchanger is checked before any refrigerant work is considered.
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.
