FAQs

Benefits

  • Energy-efficient operation

  • Heating and cooling in one system

  • Quiet performance

  • Easy installation

  • Individual room control

Considerations

  • Best for single rooms or zones

  • Indoor unit is visible

  • Requires professional installation

  • Regular filter cleaning is recommended

  • Correct sizing is important for efficiency and comfort

The right size depends on room size, ceiling height, insulation, window size and how much sun the room gets.

As a rule of thumb:

  • Bedrooms: 2.5–3.5 kW.

  • Living areas: 5.0–7.0 kW.

  • Large open-plan spaces: 8.0 kW+.

An installer can confirm with a heat load calculation.

Yes. Modern split systems are among the most energy efficient ways to heat and cool a home.

Look for:

  • High star ratings (Cooling and Heating).

  • Inverter technology Zoning by room (only heat/cool where needed).

Yes. Reverse-cycle split systems both heat and cool and are very efficient, even in colder climates.

They use electricity to move heat rather than create it, making them cheaper to run than many traditional heaters.
