Common questions

Why is my Daikin unit flashing its indicator light in Houghton Estate?

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.

Do you top up gas without finding the leak?

No. A weighed charge into a leaking system is money out the window, so the leak is found and repaired first, then the system is evacuated and charged to the plated weight.

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.
