Heat Pump Icing Up in Winchester Hills
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 Winchester Hills.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Winchester Hills sits within the Alberton belt, with larger stands, long hot water runs and frequent pool heating. Static pressure and dead-leg length are checked as part of any hot water complaint here. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.
