Room load
Insulation, glazing, orientation, air leakage and room layout affect heating and cooling demand. Floor area alone is not a complete sizing method.

Residential split-system range
Comfort depends on the room and the installation.
Daikin’s residential range includes Alira X and other split-system families. Alira X combines reverse-cycle heating and cooling with built-in Wi-Fi control, but capacity and energy-label ratings vary by model. Room sizing and unit location determine whether a particular model is suitable.
Seasonal performance
Read the heating and cooling energy label for the appropriate climate zone and exact model. One star rating does not describe a whole brand.
Airflow and placement
Indoor airflow, outdoor clearances, condensate drainage and sound influence how comfortably the system works in your home.

Warranty and support
Check the coverage for your model.
Warranty terms depend on the exact model, installation and use. We include the applicable Australian warranty documents with the quote.
The equipment
Check which components are covered, the warranty term and any registration, usage or servicing conditions.
The installation
Your quote should identify the installation work, commissioning, handover and support contacts.
The documents
Keep model and serial numbers, the invoice and the applicable Australian warranty. Manufacturer warranties sit alongside Australian Consumer Law rights.
Planning the system
Assess heating and cooling separately.
Running costs depend on room demand, outdoor conditions, setpoints and tariffs. Compare the exact indoor and outdoor unit combination.
Right-sized output
Check minimum and maximum operation as well as nominal capacity for the room’s needs.
Climate-zone label
Compare heating and cooling performance for your location using the selected model’s label.
Operating pattern
Consider occupancy, zoning and the hours each room needs conditioning.
