Heat Pump Making Noise in Lone Hill Ext
Rattling, grinding, screeching or loud humming during operation. This page covers how we diagnose and repair it on heat pumps in Lone Hill Ext.
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.
Lone Hill Ext is an extension of Fourways with a mix of original and renovated housing, so geyser positions, pressure control and pipework standards vary stand to stand. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.
