Should I just replace the current machine 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 an air conditioning specialist check your requirements as some factors may have changed since your current unit was installed. As a helpful guide to finding what size 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 air conditioner you need for your room or home is to contact one of our Fujitsu Authorised Partners who are able to assess your space and determine the best unit to suit your needs. To locate a Fujitsu Authorised Partner, please visit the Find A Stockist page and simply enter your postcode or suburb. Alternatively, contact us on 1300 882 201 for further assistance.
