Annual service to keep heat pumps efficient: coil clean, descale, sensor test and charge verification. In Waterfall Country Estate this is corporate & commercial work on all heat pumps systems, attended within about 60 minutes of dispatch.We work across every major brand installed in Waterfall Country Estate, and diagnostics start from the plated design data rather than a guess.Leaks are found before gas goes in: nitrogen pressure test, electronic sniffer and UV dye, then a triple evacuation and a weighed charge.Strict HOA: screened condensers, approved bracket types and weekday-only works. Heat Pump Services bookings in Waterfall Country Estate are logged against Block 15 so we can allow for power availability on site.

Common questions

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.

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.
