Reyds Solution
What we check and repair
- Confirm actual water and ambient temperatures against controller readings

- Take suction and discharge pressures to establish charge and compressor health
- Clean the coil and verify airflow before any refrigerant work
- Repair the leak, recharge to specification and re-test temperature rise
Local Context
Why this happens in Parklands North
Recent developments with compact plant space. Very high wind exposure and constant salt-laden air off Table Bay.
We see heat pump not heating 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.
Urgent
