Pool heat pump servicing, titanium heat exchanger checks and controller fault finding. In Sandown this is sandton prime work on pool heat pump systems, attended within about 40 minutes of dispatch.On Daikin equipment specifically — inverter splits, vrv multi-storey systems and ducted plant — the faults we see most in Sandown are outdoor pcb failure after surge events and eev coil sticking on multi-splits.Every visit starts with a full diagnostic and a written quote before any part is fitted.Apartment blocks require building manager escort for roof plant. Heat Pump Services bookings in Sandown are logged against Block 4 so we can allow for power availability on site.

Common questions
Why is my Daikin unit flashing its indicator light in Sandown?
A flashing operation lamp means the board has logged a fault code. Pressing the cancel button on the remote and holding it cycles the code out; U0 points to a low charge, U4 to a communication fault between indoor and outdoor units, and A5 to a freeze or high pressure trip.
Why is my pool heat pump tripping on flow error?
Nine times out of ten it is a partially blocked filter, a closed valve or a failing flow switch. Water flow through the exchanger is checked before any refrigerant work is considered.
Do you charge a callout fee?
A standard callout and diagnostic fee applies and is quoted upfront. It is credited against the repair when you accept the quote.
