Audits of installations

Information for suppliers and installers about audits aimed at improving safety and quality standards and protecting workers and customers in this program.

Solar Victoria's audits are making sure reverse-cycle air conditioners installed through the Home Heating and Cooling Upgrades (HHCU) Program are safe. Audits drive continuous improvement and mean that installation problems are dealt with promptly.

Approved suppliersExternal Link or installers who were found to be doing the wrong thing, resulting in non-compliant and unsafe installations, may have been excluded from our program.

Purpose of an audit

The purpose of these audits was to identify issues that need improvement and to ensure the safety and quality of systems and installations.

Auditors would look at the quality of the work, whether there were issues that needed to be followed up with the approved supplier, and ensured installations comply with the latest standards.

Audits provided a valuable picture of the standard of work being delivered under the Home Heating and Cooling Upgrades Program, with feedback provided to the heating, ventilation, air conditioning and refrigeration (HVAC-R) industry for further action or improvement.

Steps in the audit process

The audit process involves the following steps.

Audit committee

Some issues will be considered by an audit safety committee. The committee includes members from

This group will consider any action already taken by individual agencies and determine whether the matter needs to be referred to Solar Victoria for further action.

Others notified of unsafe installations

If a reverse cycle air-conditioner installations is found to be unsafe, or has major non-compliance issues that require rectification, we will inform Energy Safe VictoriaExternal Link and the Victorian Building AuthorityExternal Link .

Other checks on reverse-cycle air conditioners

In addition to the Home Heating and Cooling audits, a Licensed Electrical Inspector (LEI) will carry out an electrical inspection where a switchboard upgrade was done, and a Certificate of Electrical Safety (COES)External Link issued prior to the system being connected to the distribution network.
