Common questions
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.
Can you work after trading hours?
Yes. Retail, restaurant and office work is routinely scheduled at night or early morning under a permit-to-work so trading is not interrupted.
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.
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.
