Seems now for certain that there is a problem with pre install. The aircon installers tell me now that there appears to a small hair line crack in the pre installed piping and this is causing a loss of gas once the air con units are switched off. With reduced gas the air con systems shut down to protect the units
I am now seeking advise on how I will proceed and resolve the problem.
I believe that the builders work is insured ( as in the UK for 10 yrs). So that is my first source of getting the problem fixed. Aircon installers tell me it is possible to locate the faulty pipe and simple for a builder to replace the section of the pre installed piping.This will fix my problem.
Has anyone had a similar problem and how has Polaris World supported them in getting the builders to fix the pre installed piping?
I have as nicw suggested, contacted Resortalia by e mail, but heard nothing yet.
