Common questions

How quickly can a coldroom be back at temperature?

Once the fault is cleared, a well-insulated coldroom pulls back down within two to four hours. We advise on stock protection during that window.

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.
