Heat Pump Making Noise in Lower Houghton
Rattling, grinding, screeching or loud humming during operation. This page covers how we diagnose and repair it on heat pumps in Lower Houghton.
This fault is normally treated as scheduled work because the plant remains usable, but the fault will get more expensive the longer it is left.
Lower Houghton is a high-value residential pocket of Rosebank, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.

FAQs
Frequently asked questions
What causes heat pump making noise?
The usual causes are worn fan bearings, loose fan blade or damaged shroud, compressor mounting rubbers perished, refrigerant flow noise from low charge. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Isolate fan and compressor noise separately; Inspect mounts and fasteners; Check charge and superheat; Vibration inspection of the pipework runs. The readings are recorded so the repair decision is based on data.
Can I keep using the system in the meantime?
Usually yes, for a short period, but efficiency and component life are both being lost while the fault persists.
Do you attend this fault in Lower Houghton?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Lower Houghton falls inside our core northern-suburb route, so response is normally same-day for loss-of-hot-water call-outs.
