Should I just replace the current unit with a new one of the same capacity or should I use the Fujitsu Assist Tool to check the sizing?

It is always best to have a specialist check your requirements as some factors may have changed since your current unit was installed. As a helpful guide to finding what size heat pump / air conditioner you may need, you can use the Fujitsu Assist Tool, located on our website. However, the best way to find out what size unit you need for your room or home is to contact one of our Fujitsu Accredited Installers who are able to assess your space and determine the best unit to suit your needs. To locate a Fujitsu Accredited Installer, please visit the Find A Stockist page and simply enter your postcode or suburb. Alternatively, contact us on 04 568 8761 for further assistance.
