Local Context
Why this happens in Franschhoek
Boutique hotels, restaurants and estate homes with heated pools. Hot dry summers and genuinely cold winter mornings inland — the widest ambient range we service.
We see heat pump not switching on 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.
