Heat Pump Making Noise in Northwold Ext
Rattling, grinding, screeching or loud humming during operation. This page covers how we diagnose and repair it on heat pumps in Northwold 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.
Northwold Ext is an extension of Randburg with a mix of original and renovated housing, so geyser positions, pressure control and pipework standards vary stand to stand. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.
