Waterfall Ridge · Priority
Heat Pump Icing Up in Waterfall Ridge
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 Waterfall Ridge.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Waterfall Ridge sits within the Midrand 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.

FAQs
Frequently asked questions
What causes heat pump icing up?
The usual causes are defrost sensor or board failure, low refrigerant charge, restricted airflow from a dirty coil, fan motor running slow or intermittently. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Observe a full defrost cycle; Check defrost sensor resistance; Airflow and coil condition inspection; Charge verification. The readings are recorded so the repair decision is based on data.
Can I keep using the system in the meantime?
Usually yes, for a short period, but efficiency and component life are both being lost while the fault persists.
Do you attend this fault in Waterfall Ridge?
Yes. Midrand and Centurion sit between the Johannesburg and Pretoria routes, so attendance windows are usually the shortest of any area. Waterfall Ridge visits carry heat pump and geyser spares together, since both are commonly installed on the same property.
