Qualified Tradesmen
First of all, you need to ensure that the AC service is registered and has the necessary licenses available for providing AC maintenance services regarding carrier air conditioning. If the AC specialist is listed as a qualified tradesman then you can rest assured that it has the proper accreditation for working as an AC maintenance services provider in Australia.
BSA License
AC specialists having a BSA license are far more trustworthy than those that don’t have it. The simple reason for that is that such services are aware of the regulations imposed by the Building Services Authority. Such AC services can ensure that you follow the regulations and are not in violation of them when your AC is being installed.
Public Liability Insurance
It is always a good idea to look for service providers that have public liability insurance. The reason for this is that it ensures that you won’t have to pay anything if any accident happens during the installation or maintenance of the AC unit.In such cases, the AC service will provide insurance coverage for any damages.
ARC License
ARC or Australian Refrigeration Council provides licenses to people who have proven their ability to handle refrigerants. So, make sure that the AC service you are hiring has technicians with ARC licenses in their possession.
