Built for Australian conditions
One outdoor unit does two jobs: efficient cooling through summer, efficient heating through winter.
Inverter Efficiency
Heats and cools fast, then runs smart to hold a steady temperature and keep running costs down.
HEPA Filtration
Reduces 95% of bacteria and removes 99% of dust particles for healthier indoor air.
Whisper-Quiet
Indoor sound as low as 20.5 dB(A) on minimum fan speed, with Sleep Mode for undisturbed nights.
Match capacity to room size
A general guide only. Ceiling height, insulation, sun exposure and open-plan layouts can all shift this, so call us if you’re unsure.

Supply Only: Installation Arranged Separately
Split system installation must be carried out by a licensed technician holding a current ARC refrigerant handling licence, with electrical work completed by a licensed electrician in accordance with AS/NZS 3000, AS/NZS 5141 and AS/NZS 5149. Contact us for an installation quote in your area.
Common questions
What’s the difference between cooling and heating star ratings?+
Every split system carries separate star ratings for cooling and heating, each further broken down by climate zone (hot, average, cold) under the Zoned Energy Rating Label. A higher star rating means lower running costs for that function in that climate.
Can I control the PX Series from my phone?+
Yes, every model has built-in Wi-Fi and works with the free NetHome Plus app, plus Google Home and Amazon Alexa for voice control.
What refrigerant do these units use?+
All PX Series models use R32 refrigerant, which has a lower global warming potential and higher efficiency than older refrigerants, with a smaller charge required.
Do I need a licensed technician to install my air conditioner?+
Yes. Split system air conditioners must be installed by an authorised person holding a current ARC refrigerant handling licence, with electrical work carried out by a licensed electrician.
