Board-level diagnostics for inverter heat pumps showing intermittent faults or poor COP. In Lonehill this is luxury gated estates work on inverter heat pump systems, attended within about 65 minutes of dispatch.We work across every major brand installed in Lonehill, and diagnostics start from the plated design data rather than a guess.Compressor swaps are done with a full system flush, new drier and an oil-charge check so the replacement is not killed by the original contamination.Most complexes are boomed with visitor biometrics. Heat Pump Services bookings in Lonehill are logged against Block 12 so we can allow for power availability on site.

Common questions

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.

Do you charge a callout fee?

A standard callout and diagnostic fee applies and is quoted upfront. It is credited against the repair when you accept the quote.

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.
