| R32 | HFC (A2L, mildly flammable) | 300-340 kPa at 7 degrees C evaporating | 2 700-3 100 kPa at 45 degrees C ambient | Current-generation inverter splits and heat pumps. |
Common questions
Why is my Daikin unit flashing its indicator light in Paulshof?
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.
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.
What does an annual service contract include?
Scheduled visits, priority response between visits, a written condition report per unit and fixed labour rates for the contract year.
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.
