Heat Pump Making Noise in Randburg
Rattling, grinding, screeching or loud humming during operation. This page covers how we diagnose and repair it on heat pumps in Randburg.
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.
Large stock of 1970s–1990s homes with ageing 150–200 L geysers, plus a spread of small commercial and light industrial units along Malibongwe. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.
