Common questions
Why is my Daikin unit flashing its indicator light in Rosebank Mall Precinct?
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.
Can you work after trading hours?
Yes. Retail, restaurant and office work is routinely scheduled at night or early morning under a permit-to-work so trading is not interrupted.
Is a compressor replacement guaranteed?
Yes. Replacements are done with a system flush and new drier, and both part and workmanship are warranted, provided the original cause of failure is corrected.
How fast can you get to me?
Emergency callouts are dispatched to the next available technician, with the arrival window confirmed by SMS when the vehicle leaves.
