Heat Pump Icing Up in Benoni
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 Benoni.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Light industry, schools and hostels with large-volume storage geysers and boiler-fed hot water. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.
