Common questions
Why is my Daikin unit flashing its indicator light in Carlswald?
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.
