Common questions

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.

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.

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.
