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.
Is a heat pump geyser worth repairing or should I replace it?
If the tank and compressor are sound, repairs are far cheaper than replacement. Where the compressor has failed on a unit older than eight years, we quote both options side by side.
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.
