Common questions

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.

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.

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.
