Common questions
Do you stock Alliance parts in Sandton CBD?
Yes. Alliance is locally supported, so boards, sensors, capacitors and fan motors are available quickly, which keeps repair times short.
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.
How fast can you get to me?
Emergency callouts are dispatched to the next available technician, with the arrival window confirmed by SMS when the vehicle leaves.
Do you top up gas without finding the leak?
No. A weighed charge into a leaking system is money out the window, so the leak is found and repaired first, then the system is evacuated and charged to the plated weight.
