Domestic hot water heat pump repairs, element and controller replacement, and efficiency restoration. In Bryanston this is sandton prime work on domestic heat pump geyser systems, attended within about 50 minutes of dispatch.We work across every major brand installed in Bryanston, 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.Several sectional-title clusters require HOA sign-off for outdoor unit placement and noise limits. Heat Pump Services bookings in Bryanston are logged against Block 9 so we can allow for power availability on site.

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 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 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.
