Heat Pump Icing Up in Glenvista Ext
Ice forms on the evaporator coil and does not clear between cycles. This page covers how we diagnose and repair it on heat pumps in Glenvista Ext.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Glenvista Ext is an extension of Alberton 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.
