Installed prices by range
Panasonic Z
Premium ★ Most popularLiving areas and family homes that want app control, air purification and even airflow as standard. Matt's personal recommendation: built-in Wi-Fi and nanoe™ X air purification as standard, at a sharper price than the equivalent Daikin.
Panasonic RZ
PremiumAnyone who wants premium-brand reliability at the best price and doesn't need app control or air purification built in.
Bedrooms and living areas where noise matters and you want a premium badge without the flagship price.
Daikin Alira X
PremiumOwners who want Daikin's best wall split: the lowest running costs, app control and air purification built in, without paying for add-ons.
Daikin Large-Capacity
PremiumLarge open-plan living/kitchen zones, big rumpus rooms, and homes where ducted isn't practical.
Our value pick: honest performance at the sharpest all-in price we install — from $1,490 supply and installed. Full sizes, prices and specs live on the Athena page.
