Common questions

Is a heat pump geyser worth repairing or should I replace it?

If the tank and compressor are sound, repairs are far cheaper than replacement. Where the compressor has failed on a unit older than eight years, we quote both options side by side.

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.
