This installation package includes standard single storey back to back installation, which comes with a licensed installer, compliance certificates, up to 2.5 metres of pipework connecting the indoor head unit and outdoor compressor unit, up to 20 metres of internal roof cable run, PVC ducting to conceal pipe work and electrical connections, and a weatherproof safety isolation switch mounted near the outdoor unit. In some cases, additional charges may apply depending on the layout, location and structure of your house. Your installer will go over the reasons for any additional charges before proceeding. When you arrange your installation through us, your contract will be with Zwecks, a licensed contractor, and not with Kogan Australia Pty Ltd. Zwecks will guarantee the services of a licensed installer who specialises in air conditioner installations. This is to ensure that your investment is in good hands. Please make sure you have the relevant approvals from landlord, building owners or strata before the installation as your installer may request this information.
