Common questions

Do you stock Alliance parts in Dunkeld West?

Yes. Alliance is locally supported, so boards, sensors, capacitors and fan motors are available quickly, which keeps repair times short.

How often should an aircon need re-gassing?

A correctly installed system should never need gas. If it does, there is a leak, so we pressure test and repair the leak before charging rather than topping up annually.

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.
