Heat Pump Icing Up in Hurlingham Estate
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 Hurlingham Estate.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Hurlingham Estate is an estate development adjoining Sandton, with standardised heat pump and geyser installations fitted at build and now reaching first major service intervals. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.
