Common questions
Do you stock Alliance parts in Kyalami Estates?
Yes. Alliance is locally supported, so boards, sensors, capacitors and fan motors are available quickly, which keeps repair times short.
Do you work inside gated estates?
Regularly. Technician details, ID numbers and vehicle registration are submitted to the HOA or gatehouse before the appointment so access is cleared in advance.
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.
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.
