Common questions
Is a heat pump geyser worth repairing or should I replace it?
If the tank and compressor are sound, repairs are far cheaper than replacement. Where the compressor has failed on a unit older than eight years, we quote both options side by side.
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.
