Local Context
Why this happens in Plumstead
Suburban family homes where replacement of failed geysers is common. Cooler, wetter winters on the mountain side with damp mornings affecting defrost cycles.
We see heat pump compressor fault across domestic geyser retrofits, integrated hot water systems, pool plant and commercial installations. The diagnosis is the same discipline every time: prove the fault with readings before replacing anything.
