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 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.

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.
